10 BEST AIR PURIFYING INDOOR PLANTS FOR BIOPHILIC DESIGN | Architalktural

10 BEST AIR PURIFYING INDOOR PLANTS FOR BIOPHILIC DESIGN

In our increasingly urbanized world, many of us find ourselves spending more time indoors than ever. Unfortunately, our built environments often lack the visual, tactile, and air-quality elements that inherently connect us to nature—elements we instinctively long for. This is where biophilic design comes into play. By integrating natural materials, ample daylight, scenic views, and lush greenery into our interiors, we can dramatically improve our well-being, lower stress levels, and enrich our surroundings. A highly effective way to achieve this transformation is through the use of indoor plants, which not only bring beauty and texture to our spaces but also purify the air we breathe, making our home or office a healthier haven.

OBJECTIVE

In this blog, we delve into ten exceptional air-purifying plants: the snake plant, spider plant, ZZ plant, pothos, peace lily, monstera, fern, English ivy, cactus, and aloe vera. Each of these plants not only adds visual appeal to your space but also plays a crucial role in improving indoor air quality. No matter your interior design style—be it minimalist, tropical, Scandinavian, or Bohemian—these plants can transform your home into a biophilic oasis, promoting a healthier and more vibrant indoor atmosphere. Embrace nature’s beauty and enhance your living environment with these remarkable plants!

Plant Descriptions

For each plant, I’ll include: key aesthetic/biophilic design contributions, the types of air pollutants they help mitigate, and care tips that support their optimal performance.

Snake Plant

1. Snake Plant (Sansevieria / Dracaena trifasciata)

• Aesthetic & Biophilic Value: Tall, upright, sword‑like leaves give strong vertical form; great for defining corners, lining hallways, or structuring a space. Its bold, architectural profile adds contrast in texture (with smoother leaves) and color (often variegated edges or bands). Works well in minimalistic designs as a sculptural element.

• Air Purification Benefits: Known from NASA’s Clean Air Study to remove toxins such as formaldehyde, benzene, xylene, and trichloroethylene. It also continues to release oxygen at night (unlike many plants), which makes it good for bedrooms.

• Care: Very low maintenance. Tolerates low light, needs infrequent watering (soil should dry between waterings). Avoid overwatering to prevent root rot. Strong in neglect.

Spider Plant

2. Spider Plant (Chlorophytum comosum)

• Aesthetic & Biophilic Value: Its arching, variegated leaves and cascading “spiderettes” (baby offshoots) offer movement, texture, and layers. Hanging baskets and shelves are good locations; its airy structure softens rigid geometry in interiors. Very forgiving plant that gives a lush, relaxed feel.

• Air Purification Benefits: Effective at removing formaldehyde, xylene, and carbon monoxide. Recognized in many surveys/NASA studies. Good at filtering indoor pollutants from furnishings, adhesives, and synthetic materials.

• Care: Prefers bright, indirect light but tolerates moderate shade. Likes moist but well‑draining soil; allow topsoil to dry a bit between waterings. Mist occasionally to reduce dust on the leaves, which helps with air filtering.

ZZ Plant

3. ZZ Plant (Zamioculcas zamiifolia)

• Aesthetic & Biophilic Value: Glossy, dark green, waxy leaves on upright stems; low, sculptural silhouette. Offers high contrast in tone and sheen; works well as an accent piece or in low‑light parts of the house (since it tolerates shade). Its robustness embodies the “resilience” aspect of biophilic design—forms that endure and adapt.

• Air Purification Benefits: Helps remove VOCs such as benzene, toluene, and xylene. Though less is known compared to some of the classic NASA plants, multiple sources list it among effective air purifiers.

• Care: Very low maintenance. Needs bright indirect to moderate light but tolerates quite low light. Water sparingly; let soil dry between waterings (its rhizomes store water). Keep in well‑draining soil; avoid waterlogging.

Pothos

4. Pothos (Epipremnum aureum, “Golden Pothos,” etc.)

• Aesthetic & Biophilic Value: Trailing vines, heart‑shaped leaves often variegated (gold, cream, white, etc.). Excellent for adding soft curves, layering, draping, and green cascades from shelves or hanging planters. Its vines help visually connect the floor, middle, and ceiling levels in a room, supporting spatial biophilic layering.

• Air Purification Benefits: Known to absorb formaldehyde, benzene, and xylene. Very forgiving plant, often used in workplaces and homes for its air-cleaning qualities.

• Care: Thrives in bright, indirect light but tolerates lower light. Keep soil lightly moist, but do not overwater; let the top layer dry somewhat. Regular pruning of vines helps keep aesthetic shape and stimulates fuller growth.

Peace Lily

5. Peace Lily (Spathiphyllum spp.)

• Aesthetic & Biophilic Value: Elegant white spathes (flowers) contrasting against glossy deep green leaves provide focal interest and a soothing, tranquil presence. Great in low to medium light, good for corners or areas that need a calming feature. Also adds softness through its curved flower and foliage forms.

• Air Purification Benefits: Removes pollutants like benzene, formaldehyde, trichloroethylene, and ammonia. Also reputed to help reduce mold spores in air and increase indoor humidity (beneficial in dry climates).

• Care: Prefers medium to low indirect light. Soil kept moist (but not waterlogged). Droops visibly when dry (which is a visual cue). Be cautious if there are pets, as parts are toxic if ingested.

Monstera

6. Monstera (Monstera deliciosa, etc.)

• Aesthetic & Biophilic Value: Large leaves with split or perforated forms create dramatic shadows and patterns of light through foliage, which is very biophilic. Their scale can give a tropical feel, help fill vertical space, and emphasize lush, nature‑like interiors. Provides a strong “leafy” presence.

• Air Purification Benefits: While Monstera is not always one of the headline plants in older NASA lists, more recent design/houseplant sources include Monstera among those that help improve indoor air quality (removal of VOCs, etc.). Also, its large leaf surface area helps in absorbing pollutants and dust.

• Care: Thrives in bright, indirect light. Needs well‑draining soil and regular watering (keeping soil slightly moist). Likes support (a stake or moss pole) for vertical growth if desired. Avoid direct harsh sun, which can scorch. Also,  dust leaves occasionally to keep stomata open.

Fern

7. Fern (e.g., Boston Fern Nephrolepis exaltata or other indoor fern species)

• Aesthetic & Biophilic Value: Feathery, delicate foliage adds softness, texture, and richness. Ferns evoke shade, moisture, and leafy forest understory ambience. Great for humid areas like bathrooms, kitchens; can be used in planters at various heights to create layered green zones.

• Air Purification Benefits: Known to remove formaldehyde, xylene, and toluene; also naturally raises humidity via transpiration, which can help skin and respiratory comfort, and reduce dust.

• Care: Prefer bright, indirect light; keep soil evenly moist but not soggy. High humidity helps; regular misting or use of pebble trays. Sensitive to dry air and over‑drying.

English Ivy

8. English Ivy (Hedera helix)

• Aesthetic & Biophilic Value: Trailing or climbing; can cover walls, be trained over trellises; its drape softens harsh lines, adds complexity, and layers. Several cultivars feature variegated leaves, adding visual interest. They can be used in baskets or as groundcover in large planters indoors.

• Air Purification Benefits: Good at removing formaldehyde and other VOCs; also helps reduce airborne fecal particles/mold in some studies—useful for allergy relief.

• Care: Prefers medium to bright indirect light. Keep soil moderately moist; tolerates some dryness but not extended drought. Be mindful that ivy can be toxic if ingested and may require pruning to control spread.

Cactus

9. Cactus (Various succulents/cactus species)

• Aesthetic & Biophilic Value: Strong sculptural forms, variety of shapes—from columnar to round, ribbed, or spiky—which can serve as focal points or contrast in texture. Minimalist and drought‑tolerant, often in modern or desert aesthetic‑inspired interiors. Great for small spaces or for people with less time for maintenance.

• Air Purification Benefits: While cacti are not always the most prominent in VOC‑removing plant lists compared to some others, succulents in general help with absorbing CO₂, releasing oxygen, and reducing some pollutants; they also help stabilize humidity and may help trap dust or particles on their surfaces. Some sources list “succulents and cacti” among the overall category of air purifiers.

• Care: Require bright light; soil must be well‑draining; water infrequently (allow soil to dry between waterings). Overwatering is the most common cause of failure. Use containers with drainage.

Aloe Vera

10. Aloe Vera (Aloe barbadensis / related species)

• Aesthetic & Biophilic Value: Succulent form, fleshy leaves with interesting colors and textures (often a bit glossier, occasionally with pale spotting, and with architectural symmetry). Has a clean, modern yet natural feel. Also, it  is multi‑functional—gel inside has soothing properties. Good for windowsills, kitchens, bathrooms—places where its practical uses can be part of its appeal.

• Air Purification Benefits: Identified in studies/lists as helping to remove formaldehyde and benzene. It can also contribute to oxygen production, though not especially at night (unlike the snake plant). Also serves as a low‑maintenance purifier.

• Care: Needs bright, indirect to direct light; minimal watering; well‑draining succulent or cactus mix. Allow the soil to dry out substantially between watering to avoid root rot. Occasional dusting.

FINAL THOUGHTS

Introducing air-purifying plants into your interior spaces does more than enhance visual appeal—it actively promotes essential aspects of biophilic design. These elements foster a connection with nature, provide sensory richness through diverse textures, forms, and colors, soften harsh edges, and significantly improve air quality. Such plants not only elevate the aesthetics of your space with their vibrant greenery and structure but also play a crucial role in reducing harmful volatile organic compounds (VOCs), mold spores, and other indoor pollutants. Embrace the power of nature indoors for a healthier and more inviting environment!

When selecting and placing plants, consider the following to maximize both design and purification benefits:

• Distribute greenery throughout the room (not just in one corner) to increase surface area for filtering and to support visual layering.

• Match plant choices to the light, humidity, and care capacity you have—inappropriate conditions reduce both aesthetic vibrancy and purification efficacy.

• Use plants as accents or focal points: large-leaf plants like monstera, upright ones like snake plant, trailing ones like pothos or ivy, and ones with flowers like peace lily.

• Maintain them well: clean leaves (dust blocks stomata), water correctly, avoid overcrowding, and replace if plants get unhealthy.

Although one or two houseplants may not fully replace the need for ventilation or mechanical air filtration in polluted environments, integrating them with proper airflow, eliminating sources of indoor toxins (like certain paints and cleaning agents), and using a variety of plants can greatly enhance the quality of your indoor environment. Investing in plants is a simple, effective way to breathe easier and create a healthier home.

In short, by weaving in these ten plants, you can design interiors that feel alive, calming, and healthier—a hallmark of biophilic design in practice.

BOHO STYLE MEETS SUSTAINABLE ARCHITECTURE: Designing Eco-Friendly and Free-Spirited Spaces | Architalktural

 

Boho Style Living Room

BOHO STYLE MEETS SUSTAINABLE ARCHITECTURE: Designing Eco-Friendly and Free-Spirited Spaces

When envisioning boho-style architecture, many people picture vibrant textiles, eclectic furniture, aesthetic colors, and lush indoor greenery—all elements that exude a free-spirited and artistic charm. In contrast, sustainable architecture often brings to mind eco-friendly materials, energy efficiency, and a commitment to protecting our planet. At first glance, these two concepts may appear to be worlds apart: one rooted in aesthetic expression and lifestyle, the other centered on environmental ethics. However, a closer inspection reveals that boho style and sustainability are not only compatible but also beautifully interconnected, creating spaces that are both visually stunning and environmentally responsible.

OBJECTIVE

In today's environmentally conscious world, a new trend is emerging within the world of architectural design – the “sustainable bohemian design.” This approach blends the traditional bohemian spirit with a strong commitment to eco-friendly practices, ethical sourcing, and mindful consumption. If you're attracted to the charm of bohemian design but want your home to reflect your values, “sustainable bohemian interior design” provides a unique and fulfilling option. Having explored various architectural styles, I find that "Boho" or "Bohemian" style aligns closely with "sustainable architecture." This is due to the incorporation of key architectural elements that promote a sustainable lifestyle for the building's occupants.

In this blog, I will discuss the key elements of Boho design to enhance your awareness and reading enjoyment. Discover how Boho style architecture aligns with sustainable design principles. Learn how natural materials, upcycling, and a love for nature make bohemian-inspired spaces both eco-friendly and timeless.

BOHO STYLE DESIGN DEFINED IN GENERAL TERMS AND A LITTLE HISTORICAL BACKGROUND

I tried to look for the term boho or bohemian style architecture on Wikipedia.com, for our definition, but they only have it in general terms, mostly referring to fashion and lifestyle. However, according to them, the Bohemian style, often referred to as 'Boho chic,' is a fashion and lifestyle choice characterized by its unconventional and free-spirited essence. While its exact origins are debated, Bohemian style is believed to have been influenced by the nomadic lifestyle of the Romani people from the late 19th century to the early 20th century. The term 'Bohemian' itself comes from the French word 'Bohémien,' which was originally associated with the Roma community due to a historical misconception that they originated from Bohemia, a region in the Czech Republic. Throughout history, Bohemian fashion has undergone significant transformations, reflecting the cultural shifts and influences of each era. 

Today, contemporary Bohemian fashion embraces flowing fabrics, vibrant colors, and natural, woven materials, rather than knitted ones. I believe this definition also applies to architecture and interior design for furniture fabrics, and other elements. This style draws inspiration from various sources, including the counterculture movements of the 1960s and 1970s, reminiscent of the attire worn by attendees of the inaugural Woodstock music festival. The Bohemian style has gained global popularity, appealing to individuals seeking a unique and individualistic approach to fashion and lifestyle. It encourages a sense of freedom and self-expression, often attracting those who prefer to live unconventionally—sometimes in a nomadic manner—and who may choose to reside in colonies or communes, fostering a strong sense of community. 

KEY ELEMENTS OF BOHO STYLE ARCHITECTURE

1. A Love for Natural Materials

Boho design aesthetically incorporates materials such as wood, rattan, bamboo, clay, linen, and wool. These choices not only enhance warmth and texture but also align with sustainable design principles that emphasize the use of renewable, biodegradable, and locally sourced materials. By opting out of synthetic products and mass-produced finishes, both styles champion authenticity and eco-friendly living, inviting you to create a more conscious and inviting space.

Rattan furniture is made of natural material.

2. Upcycling and Reuse as a Lifestyle

Boho style stands out for its unique blend of vintage treasures, repurposed décors, and artisanal creations. This emphasis on items that are “collected over time” perfectly aligns with sustainability's circular philosophy—extending the life of materials and reducing waste. By choosing thrifted furniture, heirlooms, and repurposed pieces, you not only embrace a narrative rich in history but also play a vital role in lessening the demand for new resource extraction. Embrace boho style, and make a positive impact on our planet!

3. A Deep Connection to Nature

Boho interiors thrive on the beauty of indoor plants, earthy tones, and a harmonious layout that cultivates a soothing atmosphere. This aesthetic resonates with the principles of biophilic design in sustainable architecture, which promotes natural light, fresh airflow, and vibrant greenery to enhance the well-being of occupants. By embracing these concepts, we can create spaces that not only uplift and inspire but also reconnect individuals with the tranquility of nature, ultimately leading to healthier and more joyful living environments.

4. Supporting Local Craftsmanship

Embracing handmade textiles, artisanal furniture, and locally sourced décor is vital to achieving the essence of boho design. This not only enhances aesthetic appeal but also supports sustainable architecture by bolstering local economies and cutting down on transportation emissions. By choosing handcrafted pieces over mass-produced items, you not only enrich your space with cultural authenticity but also champion environmental responsibility, making a positive impact on our world.

5. Flexibility and Longevity

Boho style embodies the essence of adaptability, seamlessly combining layers of furniture and décor that evolve over time, telling unique personal stories instead of chasing fleeting trends. Similarly, sustainable architecture champions versatile spaces that adjust to the changing needs of their occupants, effectively reducing waste and the financial burden of constant renovations. Both celebrate longevity and flexibility, making them far superior to disposable, short-term solutions that ultimately undermine our living environments.

FINAL THOUGHTS

Boho style architecture celebrates aesthetic freedom and individuality, while sustainable architecture prioritizes ecological responsibility. However, these two styles share a powerful connection: they both promote authenticity, foster natural connections, and encourage thoughtful living. When combined, they produce spaces that are not only visually captivating but also environmentally considerate—homes that weave narratives while honoring the planet. The vibrant spirit of boho creativity harmonizes seamlessly with sustainable principles, illustrating that design and responsibility can truly thrive together. This fusion invites us to embrace a lifestyle that is both stylish and conscientious, proving that we do not have to compromise on one for the other.

FREEHAND SKETCHES AND DIGITAL METHOD IN THE DESIGN ARENA (PART 2) | Architalktural

 

FREEHAND SKETCHES AND DIGITAL METHOD IN THE DESIGN ARENA (PART 2)

This is a continuation of our 3-part mini-series, the first of which, I concluded with the following words:

“In the next episodes, we can expect AI to enter the arena. Oh well, let's just welcome it, but I believe we should not let it dominate the show. Instead, let us use our own creativity and use AI as a modern tool only that we have full control of. Use it to enhance our own ingenuity, nothing more, nothing less. So what do you think? Come, join me in this journey...”

The truth is that I have nothing against the digital method, or should I say, a design process with much precision and efficiency. Of course, we must always innovate and push forward advancements in technology, not only in architecture, but also in all fields of knowledge. My point is to utilize both manual and digital methods with a sense of balance and appropriateness. I believe that our personal creativity is a gift from the one who created us, and so, we should not let it simply slip away from our hands. In the design arena, we should not treat the digital side as an opponent, but rather consider it as a friend or teammate instead. I believe that in the field of architecture, freehand drawing and digital media should work together in harmony to meet our ultimate goal – to turn our imagination into reality.

OBJECTIVE 

Aside from my personal experiences, I occasionally used research work in Academia.com, which is supported by citations that eventually support the authenticity of this blog, which serves as a commentary on the referenced research work in return. This time, I found one that suits my objective in this blog. It's a research work submitted by Mirjana Pali, an Architecture graduate of Epoka University in Albania. So, please expect me to quote some excerpts from the research work to help us understand more deeply the objective of this blog.

A BRIEF HISTORY OF FREEHAND OR MANUAL DRAWING

In the first part of this series, I quoted from a research work mentioning the prehistoric or even neolithic era, while Pali's writings elaborate more on the Renaissance and Modern era:

“The two-dimensional drawings are traced from the ancient Egypt as the first mediums used in thinking and design process. At the time of the Renaissance, the information detected from the two-dimensional drawings wasn't sufficient and that is why Filippo Brunelleschi introduced perspective and the three-dimensional physical model. Since then, physical models have been widely used for presenting the mass, details, interior space, and structural relationships of a design, becoming a very important tool through the design process. The same methodology was also used during the nineteenth century, helping the masters in understanding better the volumes and the spaces created. It is interesting and surprising how architects like Frei Otto, Pier Luigi Nervi, Anton Gaudi proposed such complex geometries in a time when technology wasn't involved in architecture. Each of them brought an innovation in different techniques of working with physical models and templates to experiment with the free form geometries. Also, in the twentieth century architects main tools to design projects with very complicated shapes and curved forms, were the physical models of various scales.

However, the advance of technology in the areas of building, environmental control and computing, meant that architectural design processes needed to be adapted with the modern tools. (Hadjri, 2003) So, in the digital age, the designers faced a new thinking process and explored new, unconventional shapes in a more efficient and practical way.”

TRADITIONAL DESIGN MEDIUMS AND DIGITAL MEDIA

In this section, let me just give a brief commentary on the research paper done by Ms. Pali. Two major mediums were described: (1) Sketching as a medium; and (2) Modeling as a medium. Although sketching was the traditional medium used in communication between the architect and the constructors even since the Gothic era, and has been widely used for centuries, no one could prevent the use of digital sketching from entering the design world. On the other hand, modeling as a medium was not exempt from the duel. Here, the works of Antonio Gaudí were highlighted, where he uses physical and explorative tools such as hanging chain models or stacking plaster pieces. However, there were challenging factors that made the design process quite difficult. The efficiency depends on the expertise and skills of the architect, according to Ms. Pali.

ARCHITECTURE IN THE DIGITAL AGE

As per Ms. Mirjana Pali, “...the introduction of these new tools (computers) may limit the expression of the creative work. Therefore, care should be taken when using this tool in architectural design.” I absolutely agree with Ms. Pali on her point of view on this matter. I have always been pointing out that a careful sense of balance should be taken into consideration when using new and traditional tools together in the design process.

Pali mentioned about two notable architects that had opened the way to a new architecture that is born (the digital architecture): (1) Frank Gehry who used CATIA computer program, as an important design tool, to produce a smooth and well dimensioned steel structure pavilion for Barcelona; and (2) Peter Eisenman who also used computer to design the Aronoff Centre for Design and Art by generating a series of tilted building forms.

THE CHALLENGE

With regards to the computer-based design, Ms Mirjana Pali quoted that, “...it limits the creativity of the designer, who is more focused on the shape and the rules that different programs provide to him and in this way he is just producing an automatically product, that everyone could do it. So, what makes one design special from the other is the idea and the imagination behind it and not the shape or its construction. Finding a way of integrating both of these approaches would be the best and most efficient solution during the design process.”

The emergence of digital architecture has greatly influenced both the educational and working sectors, according to Ms. Pali. There has been a gap that has emerged between the actual curriculum in schools and the digital approach and which has caused some difficulties for students. She said, “One way of intervention in this process could be using combined design techniques, starting producing physical models in different scales, than following with 3-Dimensional digitalization, ending up with the 3D modeling. And in this way, we can manage better the changes happening in the modern society.” Again, this statement apparently coincided with the solution that I was trying to point out in my previous blogs concerning the “sense of balance” for both the traditional and digital design process.

For the working sector, Ms. Pali quoted some examples of programs like Rapid Prototyping, Digital Design Fabrication, CNC Machines, DIM, and BIM models are integrated in the process of creative design, in order to build a bridge between conceptual design, produced in architectural studios, and real-world construction.

Once in my career, I have encountered making a study on the use of CNC machines and how the operator should be trained in order to produce a physical model based on the samples given in physical form. However, the difficulty arose when the management decided to train the existing Machinist who used to operate the conventional machine. It has to take so much time, effort, and money to fund the training because we need to train the Machinist to be a designer first and teach him how to operate CNC. I think that’s one good example of the effect of the transition in technology.

For me, the effect of digital methods in design has a greater impact on the workforce than on schools. Students and school faculty could adjust based on the availability of equipment in carrying out the education process, but in the workforce, companies or freelancers have to meet the growing demand for digital presentations. It is because, timetable is a very critical factor in project management nowadays, and companies have to compete with rival designers who could meet the client’s requirements.

On my part, I used to be proficient in AutoCAD, but my skill gradually became stagnant as I went on and climbed the ladder for so many years with very minimal use of the software, until I turned into an intermediate user. Fortunately, Sketchup became popular and I had the chance to learn and use it as 3D modeling tool. While there are dedicated BIM software solutions like Autodesk Revit and ArchiCAD, you might be surprised to learn that SketchUp, can also be used effectively for BIM purposes.

FINAL THOUGHTS

I am finalizing this blog through an agreement with Ms. Pali's statement: “As we live in a period when digital developments are widely influencing the design process, treating the effects that cause the gap between physical and digital mediums will help in reaching the goals of this paper, in order to finalize it with a new, effective and practical design method for the architects of the digitalized age."

As we have been discussing so much about digital design and architecture, I should say that nowadays, AI technology is becoming so popular and widely used in the design industry. It is so phenomenal, and its rapid growth far exceeds all the recorded advancements in the world of digital technology. It is so imminent that even non-professionals can create something that appears professional to many, not only in architecture and interior design, but in almost every field: from song composition and music arrangement to creating artworks, graphic design, and creative writing, among many others. Now, we couldn’t hide the fact that it seems so threatening for designers like us, huh? What do you think? Let’s talk more about it on the last episode of this series. Thanks for following.

FREEHAND SKETCHES AND DIGITAL METHOD IN THE DESIGN ARENA (PART 1) | Architalktural

 

FREEHAND SKETCHES AND DIGITAL METHOD IN THE DESIGN ARENA (PART 1)

I strongly believe that the traditional freehand sketching method in design, especially in architecture, should be treated the same way as how we conserve our own cultural heritage. That would include the way we preserve our ancestral homes as part of our advocacy for sustainability and continuity. The traditional freehand sketching style deserves a place in the heart of every architect who doesn't want the style to simply slip away from our individually gifted hands. - Joey Castaneda 

 

Throughout the years, computer technology (not to mention the emergence of AI) has gradually invaded the world of design. This shift is much like the impact of modern machinery in various industries and crafts, where machine production has replaced handmade methods. Freehand sketches used to be the star of the show for centuries, a fundamental knowledge in architectural design education, even from the generation where I came from (1980’s), yet the tradition has been facing significant challenges due to the appeal of the digital revolution. It has influenced all fields, prompting educational institutions to include relevant study materials in their curriculum. As a result, architectural students are encouraged to adopt these digital tools, making it increasingly challenging to maintain proficiency in traditional sketching techniques amid the rapid and extensive development of design applications.  

 

The question is whether freehand sketches still retain their important position in light of the development of computer applications. Furthermore, can an architect design without the aid of freehand drawing these days? I’ll leave the challenge to you.  

 

OBJECTIVE 

As part of my advocacy for the conservation of cultural heritage, I wrote this blog post. Despite the advancements in technology, I believe that the old-fashioned technique of freehand sketching and rendering should be maintained. However, I believe this fight should begin with us, pioneer architects and educators. We should not let the advancement swallow the tradition and let it totally diminish from the industry. In the fight for cultural preservation, our ancestors won. They took care of it for centuries, and they earned the victory because the evidence is still intact to this date. 

 

DEFINING ASSOCIATED KEYWORDS 

The first thing to do is to identify the subject matter, starting with its keywords and their definitions. I referred to some useful vocabulary references to find the easiest non-technical definitions. 

 

FIRSTLY, what is design? Wikipedia says, "A design is the concept of or proposal for an object, process, or system. The word design refers to something that is or has been intentionally created by a thinking agent, and is sometimes used to refer to the inherent nature of something – its design." Sounds like a great definition, but way too technical for my readers. So anyway, since I love my readers, I decided to take a look at how educators define it. I went to research work done by a university faculty member of Mattaria-Helwan University in the mid-east region, Ehab Nasr (see citations). According to Nasr, "Design is a creative process which brings an idea to reality." Wow! That was so simple and direct to the point. So, I think let’s just stick to the professor's definitions. 

 

Our next keyword is "freehand sketching." - "Freehand sketches are a translation or expression of one's thought within an understandable and intelligible frame."  

 

Lastly is "digital architecture." - "The digital architecture is a new type of architectural engineering produced by digital technologies and accompanied by an emerging new approach in the forms and functions. The digital architecture uses the computer models, simulation, programming and images for creating the material architectural model."

 

 

A BRIEF HISTORY OF FREEHAND DRAWING 

According to a research work entitled Asia and Middle East Freehand Drawing and Architectural Expression by Hanif Budiman, Ibrahim Numan, Noor Cholis Idham (see citation): 

“Drawing is a fundamental form of human expression. Prehistoric drawings depicting aspects of early societies, such as hunting scenes, have been found in caves in southern Europe (Moran, 2013). Humans used drawing as a way of expressing their existence. The other earliest type of drawing was also found on the walls of caves in India, China, Australia, South America, even in Celebes in Indonesia. The drawing produced by Neolithic times were eventually stylized and simplified into symbol systems (proto-writing) and eventually into early writing systems. The development of the drawing is founded in early civilizations such as in the Indus valley and Egypt. This idea is a picture symbol or pictogram, a symbol pattern that has been arranged as a communication language with a certain pattern that implies a certain purpose.” 

 

In other words, drawing originated from the prehistoric writings of our ancestors. Therefore, drawing started as a means of communication and endures up to this time when we perform drawing, regardless of whether it is freehand or digital, in communicating with our clients as part of the planning and design process. 

 

THE ROLE OF FREEHAND SKETCHING IN THE DESIGN PROCESS 

It would be very straightforward to say that freehand sketching is still essential in the process of architectural planning and design. We cannot deny that not even the design trend, or technological advancement to the extent of the introduction of AI, could eliminate the use of the freehand sketch method. Before we can finalize the design using the digital method, it should always begin with the conceptualization and analysis stage which is best and quickly done by applying freehand sketching. For a detailed example of the process, I refer to a figure below taken from Mattaria–Helwan University research work by Ehab Nasr (see citation): 

 

THE IMPORTANCE OF FREEHAND SKETCHES 

Not only in architecture, but even in other fields of art such as traditional painting, artists always ought to begin by sketching the draft before the paintbrush touches the canvas. That’s where we can see the importance. In a discussion of this topic, a like-minded friend encouraged that if we push to keep the artistic side alive rather than letting the focus be purely on efficiency, maybe we can shift the trend. I kind of agree with this; just like the seafarers, I guess we really should shift the stirring wheel to reach our target destination.

For digital artists, it's a relief to know about the invention of drawing tablets where they could apply freehand sketching through a digital pen using the application software. This is a good example of a mixed design method. Architects performing conceptual planning could make use of this combined method that maintains the application of artistic skills and digital technology simultaneously. Therefore, finished products are both aesthetically and efficiently designed. 

 

USES OF FREEHAND SKETCHES IN DESIGN 

Based on the outline in Nasr’s research, the following are the uses of freehand sketches: 

A. Thinking tool: It is a means for generating, conceiving, putting forth and testing the ideas (visual - inspiration process development - design ideas crystallization - imagining - noticing).  

B. Communication tool: Freehand sketches are means of communication between the architect and himself, the architect, work team, the professor and architectural student. It is a means of dialogue between the architect and the project owner as an abstract language on understanding and communication between the parties of the design process.  

C. Interpretation, analysis and comparison tool: It helps in making the vision and interpretation of the design problems and its solutions and comparing between alternatives for choosing the best. 

D. Expression of innovation: The individual expression of the initial idea and it is also means of the innovating process; expression of an idea whether Interpreting, explaining, visual, recording the mental impressions.  

E. Exploration and development tool: Whereas it is used as means of exploring the design problems and finding out many solutions to it. It also helps the architect to explore and understand the design form and helps in developing the ideas for reaching the final thought.  

F. Documentation tool: It is used in coordination between the eye and hand to be a mean through which the images can be imported, documented and helps also in the historical documentation. 

 

DIGITAL APPLICATION USES IN DESIGN PROCESS 

The uses of digital application in the design process include:  

• Data Collection& Analysis.  
• Conceptual Design Preparation.  
• Idea Development.  
• Computer Aided Design& Presentation (2D& 3D).  
• Simulation.  
• Digital and Physical Building Model (Generation of architectural forms)  
• Remote Collaboration.  
• Virtual Reality. 

Putting together all the information derived from Nasr's work represents the importance of freehand sketching in the design process to the extent that it can encourage architects to prevent the gradual diminution of sketching in the workplace. Instead, it should be integrated with digital methods and treated as design components working together in a system that is aimed to create aesthetic, yet efficient work of art. 

 

FINAL THOUGHTS

I would not elaborate this topic much in this blog since I want to turn this into an interesting mini-series I have in mind. I figured out that this subject could not be discussed in one sitting only and I believe the information I have shared so far would be good enough so you may understand the overview of my objective. It is the cultural identity and the sense of originality of the architect or an artist that I want to emphasize and preserve in this endeavor. The bottom line is that we should stop arguing about which one is best. Let's discuss this with a sense of balance.

In the next episodes, we can expect AI to enter the arena. Oh well, let's just welcome it, but I believe we should not let it dominate the show. Instead, let us use our own creativity and use AI as a modern tool only that we have full control of. Use it to enhance our own ingenuity, nothing more, nothing less. So what do you think? Come, join me in this journey...
