Is scenting a structural or electrical decision for an architect? Mostly neither. It is a placement decision: where the machine sits relative to a supply vent and the air return, and whether it rides the existing HVAC or is wall-mounted. The electrical load is trivial - a SOSA Vaayu draws about 5W - so the point to plan for is location, not capacity.
What happens if scenting is left until after the interior is finished? The options narrow to a visible machine, a trailing cable, or a compromised position, because the ceiling void and joinery are no longer open to run a hidden power point or an HVAC connection. Planning it during services coordination avoids all three.

Facts verified 24 August 2026 against the live SOSA product pages: the SOSA Vaayu (₹11,999) is a waterless cold-air nebuliser rated to 1000m³ (about 2,000-3,000 sq ft), with a 400ml refillable tank lasting up to about 75 days depending on intensity and run hours, a Bluetooth app and onboard buttons with 1h/4h/8h/24h timers and adjustable intensity, operation under 38dB, a DC 12V/1A power draw of about 5W, dimensions of 165 x 80.5 x 215mm at 0.9kg, freestanding or wall/HVAC mounting, auto-stop, key-lock, and CE, RoHS and SGS certification. The SOSA Angaan (₹25,999) is an HVAC nebulising diffuser rated to 3,000m³ (about 8,000-10,000 sq ft) with an 800ml reservoir, metal body, programmable schedules and operation under 42dB, connecting to the building's HVAC or running standalone wall-mounted. Neither machine integrates with a smart-home protocol, a control system, sensors or voice assistants - both are scheduled standalone machines controlled from an on-site Bluetooth app. Scent enhances the ambience and perceived quality of a space; it works alongside proper ventilation and cleaning and is not a substitute for either, and SOSA makes no claim that fragrance alone influences a purchase decision. The hotel-inspired scents are SOSA's own original interpretations; SOSA is an independent brand and is not affiliated with, or endorsed by, any hotel named for reference.

Ask an architect when to plan the lighting or the AV points, and the answer is obvious: at services coordination, before anything closes up. Scenting belongs at the exact same point in the timeline, and treating it as a finishing touch is the single most common reason a luxury home ends up with a visible machine and a trailing cable.
Quick answers — read this first
When should an architect plan scenting in a luxury home? At the services coordination stage - the same point lighting, AV and HVAC positions are locked - and before the false ceiling closes or the joinery is fitted. A wall or HVAC mount and a discreet power point for a SOSA Vaayu (₹11,999) or SOSA Angaan (₹25,999) both need to be decided on paper, not worked out afterwards against a finished ceiling.Is scenting a structural or electrical decision for an architect?

The short answer
Short answer: at the services coordination stage of the project - the same point lighting, AV and HVAC are decided - because a wall or HVAC mount and a discreet power point for the SOSA Vaayu (₹11,999) or SOSA Angaan (₹25,999) both need to be locked before the false ceiling closes and the joinery is fitted.
The pick: the SOSA Vaayu (₹11,999) per zone, stepping up to the SOSA Angaan (₹25,999) when the home runs on central HVAC.
Next step: send us the services drawings and we will mark up placement with your team - open a conversation.

Straight answer
At what stage of a luxury home project should scenting actually be decided?
During services coordination - the drawing stage where lighting circuits, AV points, HVAC ducting and electrical points are all locked against the reflected ceiling plan and the joinery layout. A SOSA Vaayu (₹11,999) or SOSA Angaan (₹25,999) needs exactly the same three things decided at that stage: a wall or HVAC mount position, a discreet power point near it, and a location clear of a supply vent or return path. None of that is a demanding ask - the Vaayu draws about 5W, which is a trivial addition to any circuit already being run for lighting - but it has to be marked on the drawing before the ceiling closes and the joinery is fitted, not decided by walking the finished site. Neither machine speaks to a control system. There is no Control4, Crestron, Lutron, KNX or Matter driver, no wifi, no cloud account, and no voice-assistant skill. Vaayu is operated from its own on-site Bluetooth app with 1h/4h/8h/24h timers; Angaan runs its own programmable schedule. Both are scheduled and standalone, which is exactly what makes them simple to specify and simple for a homeowner to run once the project is handed over. Left until fit-out is complete, the same decision has three much worse answers: a visible freestanding unit, a power cable run along a skirting, or a machine placed wherever a socket happens to already exist rather than where the air actually moves. A conversation about your project at drawing stage costs nothing and avoids all three. A portion of every order supports girl-child education through Nanhi Kali.
Plan scenting at services coordination, alongside lighting and AV - a wall/HVAC mount, a discreet power point and a position clear of a supply vent all need to be on the drawing before the ceiling closes.
The SOSA Vaayu needs only three things marked on a services drawing: a wall or HVAC mount, a nearby power point, and a position clear of a supply vent. It draws about 5W, is waterless, and runs under 38dB. ₹11,999.

The design-stage shortlist
Two machines, both decided on paper before the ceiling closes
The two machines an architect specifies
Two machines, both small enough to disappear into a services drawing rather than a finished room. Both pictures link to the product page so your design team can check the specification before it goes on the drawing.
One zone, wall or HVAC mounted
SOSA Vaayu
Waterless cold-air nebuliser, 1000m³ coverage, 5W power draw, 165 x 80.5 x 215mm at 0.9kg. Under 38dB, freestanding or wall/HVAC mount. Small enough to hide in a niche or a ceiling void.
From ₹11,999
A whole villa on central HVAC
SOSA Angaan
HVAC nebulising diffuser, 3,000m³ coverage, 800ml reservoir, metal body, programmable schedules, under 42dB. Connects to the building's air handling so nothing extra is visible in the room.
From ₹25,999
The project stage scenting actually belongs in
Three questions decide the drawing, and all three have to be answered before the ceiling closes, not after.
1
Which stage the decision belongs in
Services coordination - the same drawing as lighting and AV
A luxury home's lighting circuits, AV points and HVAC ducting are all locked at services coordination, against the reflected ceiling plan and the joinery layout. Scenting needs exactly the same three inputs - a mount position, a power point, and clearance from a supply vent - so it belongs on that same drawing, reviewed by the same team, at the same meeting. Treating it as a separate, later decision is how it ends up decided against a finished ceiling instead of an open one.
Tip: put it on the services drawing, not on a snagging list.
The Vaayu needs only a mount and a power point marked - small enough that most architects have never had to think hard about where it goes, provided it is decided in time.

What has to be locked before the ceiling closes
Mount position, power point, and clearance from a supply vent
Once the false ceiling is closed and the joinery is fitted, none of these three can be changed without visible rework. The mount - wall or HVAC - decides whether a cable or duct connection needs to be run inside the void. The power point needs to sit close enough that no cable is visible. And the position needs to be clear of a supply vent's direct throw, or the fragrance never diffuses evenly into the room.
For a whole villa on central HVAC, the Angaan connects inside the plant room, so nothing needs to be decided in the visible ceiling at all.

Why leaving it late gets worse, not neutral
A retrofit has three answers, and all three are worse than planning
After handover, a scenting decision that was never made on paper resolves itself one of three ways: a visible freestanding machine, a power cable run along a skirting or under a rug, or a position chosen because a socket happens to be there rather than because the air moves through it. None of these are dramatic failures - they are just the ordinary cost of a decision made too late, which is exactly why the fix is simple: make it on time.
Tip: the fix costs nothing extra - it only costs being early.
Marking the Vaayu's mount and power point on the services drawing takes the same five minutes as marking a downlight - and avoids the retrofit entirely.
See SOSA Vaayu →
The SOSA principle
Nobody argues that lighting should be decided after the ceiling is closed. Scenting needs the same three inputs lighting does - a mount, a power point, a position - so it deserves the same timing.
The question is never whether scenting is worth planning. It is whether it gets planned at the meeting where it is still cheap to decide.
One Vaayu per zone, one Angaan for a whole villa on HVAC
The machine choice is simple once the timing is right: one Vaayu per zone for most homes, one Angaan when the whole house already runs on central HVAC.

Once the placement is settled, the fragrance choice is the easy part - one clean, quiet profile across the whole home, ordered for every machine on the project. For the placement questions themselves, our guides on where to hide the machine in a finished interior and whether scenting has to be planned before the false ceiling and joinery are finished cover the two decisions that follow directly from this one, and the pillar guide on automating home fragrance covers what the machines can and cannot do once installed.

The SOSA design-stage specification
Both machines are sized to disappear into a services drawing rather than a finished room. The Vaayu suits a single zone and draws a trivial 5W; the Angaan takes a whole villa on central HVAC. Both are waterless and made in India, and a portion of every order supports girl-child education through Nanhi Kali.

One honest note for the specification meeting: this is a placement decision, not a power one, and it does not connect to any building control system. That keeps the ask small - a mount, a power point, and a position clear of a supply vent - which is exactly why it is worth deciding early rather than not at all. Open a conversation and we will work through the drawings with your team.

A note from Sonal
I have sat in enough services coordination meetings to know the pattern: lighting, AV and HVAC all get a line on the drawing, and fragrance gets raised, if at all, once the joinery is already being installed. By then every good answer has already closed off. The frustrating part is that scenting asks for so little - a mount, a power point, a position clear of a vent - that there was never a good reason to leave it out of that first meeting.
My advice to an architect is specific rather than general: put the Vaayu or Angaan on the reflected ceiling plan the same week the downlights and AV points go on. Neither machine speaks to a control system. There is no Control4, Crestron, Lutron, KNX or Matter driver, no wifi, no cloud account, and no voice-assistant skill. Vaayu is operated from its own on-site Bluetooth app with 1h/4h/8h/24h timers; Angaan runs its own programmable schedule. Both are scheduled and standalone, which is exactly what makes them simple to specify and simple for a homeowner to run once the project is handed over. The electrical ask is trivial - the Vaayu draws about 5W - so there is no capacity question to solve, only a placement one, and placement is exactly what a services drawing already exists to settle.
Once it is on paper, everything downstream gets easier: the electrician knows where the point goes, the joinery contractor knows to leave a niche or a clearance, and the client never sees a visible machine or a trailing cable. Everything is made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
When should an architect plan scenting in a luxury home project?
At the services coordination stage, the same drawing meeting where lighting circuits, AV points and HVAC ducting are locked, and before the false ceiling closes or the joinery is fitted. Both the SOSA Vaayu (Rs 11,999) and the SOSA Angaan (Rs 25,999) need a mount position and a power point decided at that stage, not worked out later on site.
Is scenting an electrical or structural decision for the architect to make?
Mostly neither. The electrical load is trivial - the Vaayu draws about 5W, a negligible addition to any circuit already being run - so the real decision is placement: a wall or HVAC mount, and a position clear of a supply vent's direct throw. That makes it closer to a lighting decision than a power one.
What happens if the scenting decision is left until fit-out is finished?
The options narrow to three, all worse than planning ahead: a visible freestanding machine, a power cable run along a skirting or under a rug, or a position chosen because a socket happens to exist there rather than because the air moves through it. Planning at services coordination avoids all three.
Does the scenting machine need to connect to the home's smart-home or HVAC control system?
No. SOSA Vaayu runs its own schedule from an on-site Bluetooth app with 1h, 4h, 8h and 24h timers, and SOSA Angaan runs its own programmable schedule. Neither integrates with Control4, Crestron, KNX, Matter or any voice assistant, so there is no protocol for the architect or integrator to plan into the control system.
How much does scenting add to the electrical plan of a luxury home?
Very little. The SOSA Vaayu draws about 5W on a DC 12V/1A adapter, which is a trivial addition next to lighting or HVAC circuits. The decision worth spending time on is where the power point sits relative to the mount position, not whether the circuit can carry the load.
