Founder Diaries · Architecture & Scent
Where does scent fit into a multisensory approach? Scent belongs alongside light and sound as a deliberate design layer, considered at concept stage rather than added at handover. It is unusual among the senses because smell reaches the parts of the brain tied to emotion and memory more directly than any other, so it does a disproportionate amount of the work of making a space feel like something and stay in memory. For an architect the practical question is control: a scent has to be even, restrained and always present, which is what a cold-air diffuser such as a SOSA Vaayu (Rs 11,999) delivers across an open floor of up to about 2000-3000 sq ft.
Why is scent left out of most architecture? Because it cannot be drawn, rendered or shown in a photograph, and the profession's tools - plans, sections, renders, mood boards - are all visual. A material can be specified on a schedule; a scent has had no equivalent. That is changing as controllable diffusion makes scent something you can size and specify like any other system, one machine per floor or zone, matched to the material palette.

Facts verified August 2026 (SOSA product pages): The SOSA Safar is a compact, cordless, rechargeable waterless cold-diffusion perfume diffuser priced at ₹3,999, described for use in a car, on a desk, in a handbag or a hotel room; it runs up to about 10 hours continuously or 30 hours intermittently on a single charge, has 3 speed settings and a 1h/2h/3h auto-off timer, and ships with three SOSA Hotel Collection hotel-inspired oils. It is a personal-space device for strong close-range projection and is not rated to fill a large open floor evenly. The SOSA Vaayu is a waterless cold-air diffuser priced at ₹11,999 that atomises alcohol-free, water-free fragrance oil into a dry nano-mist covering up to 1000m3 (about 2000 to 3000 sq ft) per open floor, with a 400ml tank (four 100ml oils included) that lasts up to about 75 days depending on the intensity setting and daily run hours, 1h/4h/8h/24h timers, Bluetooth app control and under-38dB operation; a very large or double-height floor may need the larger Angaan (₹25,999, ~8,000-10,000 sq ft) or Meenar (₹38,500, ~12,000-18,000 sq ft), and a multi-storey home generally needs one machine per floor. A reed diffuser (from about ₹749) is passive and cannot be adjusted in strength. Fragrance projection depends on the volume of air and on ventilation - a closed, air-conditioned room holds scent while open windows, balconies and fast fans disperse it - so the same floor area can need different power. A signature scent enhances a clean, well-ventilated room; it does not remove a musty or closed-up smell, which should be aired out first, and SOSA makes no medical or air-purification claims. The hotel-inspired scents are SOSA's own original interpretations; SOSA is independent and not affiliated with, or endorsed by, any hotel named for reference.

We already design light, proportion, acoustics and touch with real care. Then we hand over a space that has been composed for four senses and left silent on the fifth - the one most tied to memory.

What is multisensory architecture? Multisensory architecture is the practice of designing a space for all of the senses, not just the visual. It treats light, sound, texture, temperature and scent as one composed experience rather than styling the way a room looks and leaving the rest to chance. The idea is old - we have always known a cathedral, a library or a good hotel feels different in ways the eye alone cannot explain - but the vocabulary has become explicit as architects look for what separates a space that is merely photogenic from one that is genuinely memorable. Scent is the layer most often missing, because it is invisible and hard to draw.Where does scent fit into a multisensory approach?

The short answer
Short answer: multisensory architecture designs a space for every sense - light, sound, texture, temperature and scent - as one composed experience. Scent is the layer most often left out because it cannot be drawn, yet it drives memory and emotion most; a SOSA Vaayu (Rs 11,999) makes it a controllable design layer across an open floor.
The ladder: a reed for a soft scent in a small cabin; the SOSA Vaayu (₹11,999) for an even signature across an open studio or home floor up to ~2000-3000 sq ft; the Angaan (₹25,999) or Meenar for very large or double-height volumes.
Next step: shop the SOSA Vaayu, or send us the studio or project - size, layout, ceiling height and material palette - and we will help you specify it.
In this guide
Architecture is experienced with every sense, yet smell is almost always left out of the brief. A beautifully detailed studio or home can still feel anonymous because nothing anchors it in memory - and scent is the fastest route to memory there is. For an architect there are two moves. First, your own studio: a clean, material-appropriate signature that greets clients and quietly says the practice understands luxury. Second, the projects you design: scenting planned in at concept stage, the way lighting and climate are, so a villa or a showroom carries one considered signature throughout. The tool for both is an even, controllable cold-air diffuser - a SOSA Vaayu for an open studio or a home floor up to about 2000-3000 sq ft, a compact Safar for a small private cabin, and the larger Angaan or Meenar for very large or double-height volumes. A passive reed is lovely in a small cabin but disappears across a studio floor.

Straight answer
What is multisensory architecture, and where does scent fit into it?
Multisensory architecture is the practice of designing a space for all of the senses at once - light, sound, texture, temperature and scent - as a single composed experience, rather than styling how a room looks and leaving everything else to chance. Most of us already do three-quarters of this instinctively: we obsess over daylight, we think about how a room sounds, we choose materials partly for how they feel underhand. Scent is the layer that falls out of the process, and the reason is simple - it is invisible and cannot be drawn, rendered or photographed, so none of our usual tools capture it. Yet smell reaches the parts of the brain tied to emotion and memory more directly than sight or sound, which means it does a disproportionate share of the work of making a space feel like something you remember. Fitting scent into the design means treating it the way you treat lighting: decided at concept stage, sized to the volume of air, and matched to the material palette. The practical part is even, always-on control - a SOSA Vaayu (₹11,999) is a waterless cold-air diffuser that carries one restrained signature evenly across an open floor of up to about 2000-3000 sq ft on a Bluetooth app or timer. A passive reed diffuser is fine for a soft note in a single small cabin but disappears across a floor; a very large or double-height volume steps up to the Angaan. This works twice for an architect: in your own studio, and specified into the projects you design. To size it for a space, a quick note is enough.
Multisensory architecture designs for every sense; scent is the layer usually left out because it cannot be drawn, yet it drives memory most. A Vaayu makes it a controllable design layer.
Start from the space. A small private cabin can take a passive reed diffuser. An open studio or a home floor wants an even signature that does not fade or need spraying - that is the SOSA Vaayu (₹11,999, up to ~2000-3000 sq ft). A very large or double-height volume steps up to the Angaan (₹25,999); one machine per floor or zone.

The four senses architecture already designs for - and the one it leaves out
Architecture already commands four of the five senses with real skill. Looking at where each one is handled shows exactly where scent belongs - and why it keeps getting dropped.
1
The four we design
Light, sound, touch and thermal comfort
Daylight and shadow, acoustics and reverberation, the texture of a handrail, the warmth of a room in winter - these are second nature to us. We compose them because we can draw, model and specify them. They are the senses our tools already serve.
Tip: the senses we design well are the ones we can put on a drawing.
2
The one we drop
Smell has no drawing
Scent is invisible. It cannot be rendered, photographed or put on a finishes schedule, so it slips through the process - not because it matters less, but because our tools have never captured it. It is an absence of vocabulary, not an absence of importance.
3
Why it matters most
Smell owns memory
The olfactory system connects almost directly to the parts of the brain tied to emotion and memory. That is why a scent can return you to a place years later. The sense we design least is the one that decides how a space is remembered.
Tip: the layer we leave blank is the one that writes the memory.
The SOSA principle
A space can be composed for four senses and completely silent on the fifth - and the fifth is the one that decides whether anyone remembers it.
Multisensory design is not about adding a gimmick. It is about finishing a composition we have been leaving three-quarters done.
Sizing and selecting scent as a design layer, for a studio or a project
Bringing scent into the composition is two decisions - the scent family, chosen to sit with the materials, and the diffusion that carries it evenly and always. Both follow the space itself.
The SOSA scent edit
How scent enters a design - the honest options
| Scent | Why it suits the mood |
|---|---|
| Nothing / candles at handover | The default: scent is left to chance or added as an afterthought. Inconsistent, unplanned, and usually competing with the interior rather than completing it. |
| Reed diffuser | A passive, front-loaded note - lovely on a single reception desk or in a small cabin, but too quiet to hold a floor and impossible to tune. |
| SOSA Vaayu | An even, always-on signature across an open floor on a timer, sized to the volume of air and matched to the palette - scent designed in, not sprinkled on. |
One Vaayu (₹11,999) covers an open floor up to about 2000-3000 sq ft; a two-storey studio or a villa runs one machine per floor, because scent does not climb a staircase on its own, and a very large or double-height volume steps up to the Angaan (₹25,999). For a single small cabin or a one-person office a compact Safar (₹3,999) is enough. The Vaayu ships with four hotel-inspired oils, so you can choose the scent family that complements your interior - and the same thinking is exactly what you carry into the projects you design, where scent becomes one more considered layer of the brief.
Matched to your room
For an open studio or a home floor, one SOSA Vaayu (₹11,999) carries an even signature scent up to ~2000-3000 sq ft; very large or double-height volumes step up to the Angaan, one machine per floor or zone - judged by the volume of air, not floor area alone.
We have spent a century learning to design light. Scent is simply the next sense to take seriously - not louder, just no longer left blank.

The SOSA scenting range for architects
Every SOSA system here is made in India and sized to a real volume of air. A passive reed for a small private cabin, a compact Safar for one small personal space, the Vaayu for an open studio or home floor up to ~2000-3000 sq ft, and the Angaan or Meenar for very large, double-height or large commercial volumes - one machine per floor or zone. Whether you are scenting your own studio or specifying a system into a project, size by the volume of air and match the scent family to the material palette. Here is the full range.
The SOSA scenting range for architects
From a single cabin to a whole villa or showroom - matched to the volume of air, the layout and the material palette
| System | Best for | Why it works | From |
|---|---|---|---|
 SOSA Safar
|
A single small cabin, a one-person office or a reception desk | Compact cordless cold-diffusion - controllable scent on demand for one small personal space; too small for an open studio floor | ₹3,999 |
 SOSA Vaayu
|
An open studio floor or a home floor up to ~2000-3000 sq ft - the architectural workhorse | Active cold-air machine with Bluetooth app & timers - one even signature across an open plan; one per floor or zone | ₹11,999 |
 SOSA Angaan
|
A very large or double-height studio, villa floor or showroom (~8,000-10,000 sq ft) | HVAC nebulising diffuser for a very large volume of air | ₹25,999 |
 SOSA Meenar
|
The largest commercial interiors - hotel lobbies, malls, large showrooms (~12,000-18,000 sq ft) | Commercial HVAC scenting for the biggest volumes | ₹38,500 |
How to specify honestly: a reed diffuser is passive and cannot be turned up - fine for a soft background scent in a single small cabin, but it disappears across an open studio floor. The SOSA Safar is a compact, cordless device for one small personal space - a private cabin, a one-person office or a reception desk. For an open studio floor or a home floor, the even, all-day signature is the job of the SOSA Vaayu (one open floor up to about 2000-3000 sq ft), and a large multi-storey studio or villa runs one machine per floor or zone - scent does not travel up a staircase on its own. Very large or double-height volumes, and large commercial interiors, step up to the Angaan or Meenar. Two design notes: size by the volume of air (length x width x ceiling height), not floor area, because a double-height space behaves far larger; and match the scent family to the material palette - dry cedar and vetiver with concrete and oak, something warmer with leather and dark wood, something clean and mineral with marble and glass. A scent enhances a clean, well-ventilated interior; it does not mask a musty or closed-up smell, and SOSA makes no medical or air-purification claims. Specifying for a studio or a project? A quick note to us helps you size and select it.

A note from Sonal
I work with a lot of architects, and the conversation almost always starts the same way: the studio, or the project, looks extraordinary, and yet something is missing. It is nearly always scent. We design so carefully for light, proportion, material and acoustics, and then leave the one sense most tied to memory entirely to chance. A space you can smell is a space people remember - and for an architect that is true twice over, in the studio where you meet clients and in the homes and interiors you design for them.
For the studio, I usually suggest one clean, material-appropriate signature rather than anything hotel-like - dry cedar and vetiver sit beautifully with concrete and oak, something warmer with leather and dark wood, something clean and mineral with marble and glass. One Vaayu carries it evenly across an open studio floor of up to about 2000-3000 sq ft, on a timer, with no one spraying anything. A small private cabin can take a passive reed, or a compact Safar for a single desk; a very large or double-height studio steps up to the Angaan.
The second move is the interesting one commercially: specify scenting into your projects the way you specify lighting and climate. Planned at concept stage, sized by the volume of air (one machine per floor or zone, because scent does not climb a staircase on its own) and matched to the material palette, it becomes a considered layer of the design rather than something the client adds later. Everything is alcohol-free and made in India; SOSA makes no medical or air-purification claims and is independent of any hotel we reference. If you send me the space - size, ceiling height, layout and materials - I will help you size and select it.
Frequently asked questions
What is multisensory architecture?
It is designing a space for all of the senses - light, sound, texture, temperature and scent - as one composed experience, rather than styling how a room looks and leaving the rest to chance. Scent is the layer most often left out.
Where does scent fit into it?
Alongside light and sound, as a deliberate layer decided at concept stage. Smell drives memory and emotion most directly, so it does a large share of the work of making a space memorable - a SOSA Vaayu (Rs 11,999) makes it controllable across a floor.
Why do architects leave scent out?
Because it cannot be drawn, rendered or photographed. Our tools are visual, so scent slips through the process - not because it matters less, but because there has been no way to capture it on a drawing.
Is scenting a space a gimmick?
It does not have to be. Done well it is restrained and integral - one clean signature matched to the materials, sized to the volume of air. The gimmick is a loud, novelty scent; good olfactory design is the opposite.
How do I make scent a design layer in practice?
Decide it at concept stage, size it by the volume of air (one machine per floor or zone), and match the scent family to the palette. A Vaayu carries an even signature across an open floor up to about 2000-3000 sq ft; larger volumes step up to the Angaan.
