Three floors,
three separate homes
A villa looks like one house from the gate. To fragrance it is a stack of separate air volumes joined by a staircase, and most disappointment comes from buying for the house when you should be buying for the floor.
Scent does not climb stairs on its own. Decide which floor you actually want fragranced, then decide what the closed rooms need.

The answer in 30 seconds
What does a villa need?
- Count floors, then doors. Each level is its own air volume until you have checked how the staircase connects it to the next.
- One zone device for the floor you live on. Usually the living and dining level, sized on its real internal volume.वायु Vaayu
- One room device for a closed bedroom. A shut door makes it a separate problem, whatever the floor plan says.पवन Pawan
- Do not stand a machine at the foot of the stairs and hope. An open stair leaks scent upwards unevenly. It does not deliver it.
Why downstairs never reaches upstairs
The question villa owners ask me most is some version of this: the living room smells lovely, so why is there nothing on the first floor? The answer is that there was never going to be. Fragrance travels with moving air, and the air on your ground floor mostly stays on your ground floor. A staircase is an opening, not a duct.
Some scent does drift up an open stair, which is why the landing often smells faintly of the living room while the bedrooms behind their doors smell of nothing at all. Raising the setting downstairs to push more of it up is the usual mistake. The ground floor becomes heavy long before the bedrooms notice.
So plan a villa the way it is built, one floor at a time. The connected living and dining level is one volume. Each bedroom with its door shut is another. A double-height living room, if your plan has one, holds far more air than its floor area suggests and needs measuring, not guessing. I never assume a villa has one, because many do not.
| What to look at on each level | |
|---|---|
| The living level | Internal length by width by ceiling height of the connected living and dining run, in metres. This is the volume a zone device is sized on. |
| The staircase | Note whether it is open to the living room or sits behind a door or lobby. Open stairs share some air between floors. Enclosed stairs share almost none. |
| A double-height room | Measure the full height. The volume can be close to twice what the floor plan implies. Confirm it from your own section drawing, not the brochure. |
| Bedrooms | Each is its own room once the door is shut. पवन Pawan is published for one suitable room up to about 500 sq ft. |
| An upper lounge | A family lounge or home theatre upstairs is a second zone, to be measured separately. It is not an extension of the living room below. |
| Terraces and sit-outs | Outside the scope of both machines. Treat them as indoor devices. |

One of each, not two of the same
For most villas the plan that works is one zone device on the living level and one room device in the bedroom you use most. Two zone devices sounds more generous, but the second almost always ends up in a bedroom, where a machine published for a thousand cubic metres is serving a few dozen. It is also the costlier route to a worse result. Add rooms later, one at a time, once you have lived with the first two.
Both machines take the same SOSA waterless oils, so a second device never strands a bottle you have already bought.
“A staircase is an opening, not a duct. Fragrance the floor you are standing on.”
Setting it up
- Walk the house with the doors as you normally keep them. That is the home you are scenting, not the one on the drawing.
- Measure the living level in metres. Length, width and the real ceiling height.
- Place the zone device where air already moves. Near the AC return or along the main circulation, not in a corner behind a sofa.
- Start low and give it two or three days. A new space takes a little time to settle. Then turn it down, not up.
- Add the bedroom last. Give it its own timer and leave it alone.
- Judge it from the front door. Step outside for a few minutes and walk back in. Indoors your nose has already adapted.
