Five bedrooms,
five closed doors
A five-bedroom villa has a living floor that smells the way you chose and a bedroom floor that smells of nothing. That is not a fault in the machine downstairs. It is a staircase and five doors.
Upstairs is not an extension of downstairs. Decide whether you want the landing scented, one bedroom, or nothing at all, and give that choice a source of its own.

The answer in 30 seconds
Upstairs, in four decisions
- Accept that downstairs stays downstairs. The living floor has its own machine and its own air.वायु Vaayu
- Choose which bedrooms, if any. One room device each, and only where someone wants it.पवन Pawan
- The landing and corridor are optional. Scent there reaches a bedroom only while its door is open.
- Measure the real ceiling heights. Before assuming anything about the living floor.
Where the scent stops, and why
Walk up your own staircase slowly, an hour after the living room has been running, and you can find the step where the fragrance stops. It is somewhere on the flight, usually before the landing. Above that, the air belongs to the upper floor: its own windows, its own air conditioning, its own doors.
Then come the doors. A bedroom with its door shut and its own air conditioner running is as separate from the corridor as the corridor is from the ground floor. This is why raising the setting downstairs achieves so little upstairs. The scent has two barriers to cross, and it was never strong enough to cross one.
The useful question is what you actually want upstairs. Many families want nothing: bedrooms that smell of clean linen and nothing else. Some want the master bedroom alone. A few want the landing lightly scented, so that the upper floor has a welcome of its own. Each is a different, small plan.
Be realistic about the corridor. A source on the landing scents the landing. It reaches a bedroom only while that bedroom's door stands open, and stops the moment it shuts. If the aim is a fragranced bedroom, the source belongs in the bedroom.
| What each choice needs | |
|---|---|
| Nothing upstairs | Nothing. A perfectly good answer. |
| The master bedroom | One room device in that room, on its own timer. |
| Two or more bedrooms | One room device each. Ask each occupant first. |
| The landing or corridor | A room device there, if it is enclosed enough to hold scent and has a free socket. It will not carry into closed rooms. |
| The living floor | Its own zone device, sized on its measured volume, ceiling height included. |
“The scent has two barriers to cross, the staircase and the door, and it was never strong enough to cross one.”
For your interior designer: around the staircase and the bedroom corridor
On a drawing, the staircase looks like a route between floors. For fragrance it should be drawn as a boundary.
- Draw the stair as a boundary. Each floor is planned on its own side of it.
- Mark each bedroom door. And note whether the family keeps it open or shut.
- Treat the landing as a conditional zone. Only if it is enclosed, and only if it is wanted.
- Watch how the air actually moves on site. Before fixing the number of devices.
- Give each device its own accessible socket and timer. Bedrooms rarely keep the same hours.

Supadha Geethika at Velimela is listed with five-bedroom villas, one selected layout being 5,320 sq ft. That figure is a saleable area across all the floors. It tells you nothing about any one room, and the ceiling heights in particular should be measured, not assumed.
Named as an example, not as an installation. SOSA has no affiliation with the project or its developer, and nothing here describes a particular villa.
