Home sizes
Custom sizing — any carpet area, any configuration.
Most homes do not land on a round BHK number. Half-configurations, studios, duplexes, plot builds, redeveloped flats and plans that do not match the builder's drawing are ordinary work here. Send the carpet area and the real layout, and we plan to the measurement.

Homes we size to order
Each of these is planned from measured dimensions rather than from a configuration label.
- Studio and 1 RK — 250-400 sq ft. One room doing four jobs. The plan is decided by what can be hidden: a wall bed, a kitchen behind shutters, and a single storage wall that absorbs everything else.
- Half-size configurations — 2.5 and 3.5 BHK. The extra half is usually a small room with an odd proportion. It works as a study, a nursery or a dressing room — rarely as a bedroom, and planning it as one is the common mistake.
- Duplex and penthouse — 1,800-4,000 sq ft over two levels. The staircase is the design problem, not a circulation detail. Service routing between levels and the double-height volume set the material and lighting strategy for everything else.
- Independent house and plot builds — 1,200-5,000 sq ft. Interiors can be decided while the structure is still open, which is the cheapest moment to move a wall, a socket or a drain. The programme runs alongside civil work rather than after it.
- Row house and villa — 1,600-3,500 sq ft. Repeated floor plates with a private garden or terrace. The scheme has to carry from the entrance level to the top floor without repeating itself literally.
- Compact and non-standard plans — Any carpet area. Redeveloped flats, converted lofts, corner units with angled walls, and plans where the builder's drawing does not match what was actually built. Everything is measured on site before a line is drawn.
- Commercial and office fit-outs — 300-8,000 sq ft. Headcount, services and statutory clearance drive the plan. Priced and programmed the same way, against a drawing and a material schedule.
Carpet area
What changes as the square footage moves
If you know the area but not what it should contain, read across.
| Carpet area | What the plan turns on | What that means |
|---|---|---|
| Under 500 sq ft | Everything is vertical and multi-use | Loft storage over every door, wall-hung joinery, one flooring material throughout, and one palette. Furniture is chosen for what it does when it is not in use. |
| 500-900 sq ft | Storage volume is the deciding number | A workable kitchen triangle and full-height wardrobes take priority over feature walls. The living and dining have to read as one volume rather than two small rooms. |
| 900-1,500 sq ft | Rooms can take distinct characters | A whole-home palette starts to pay off, a utility zone can be closed off, and the primary bedroom can carry a dressing zone without losing floor area. |
| 1,500-2,500 sq ft | Formal and informal zones separate | The problem shifts from fitting things in to holding the scheme together across more rooms. Cornice, skirting and door profiles have to be decided once and repeated. |
| Above 2,500 sq ft | Coordination becomes the main body of work | Joinery, stone, lighting and furniture are designed together, with a full lighting scheme and scene control. Bespoke furniture is usually cheaper than buying at this scale. |
Process
How a non-standard plan gets designed
Send whatever you have
A builder's PDF, an architect's DWG, a society-approved plan, or a clear photograph of the printed drawing. If you have none of them, send the carpet area from your sale deed and the number of rooms.
We measure before we draw
Builder drawings and built reality differ often enough that we treat the drawing as a starting point. Every wall, opening, beam drop, duct and socket is measured on site and the plan is redrawn to what is there.
The scheme is planned to your numbers
Room dimensions, storage volumes and circulation are worked out against your actual carpet area rather than a band. Non-standard proportions usually mean bespoke joinery sizes, which is a specification decision, not a surcharge.
Priced line by line, the same way
The estimate runs against a material schedule regardless of the shape of the home. There is no square-foot rate to be surprised by later.
Questions
About custom sizes
My flat is 1,320 sq ft. Is that a 2 BHK or a 3 BHK plan?
Neither label decides it — the room dimensions do. At that area a three-bedroom plan works if the third room is used as a study or a nursery, and a two-bedroom plan buys you a genuinely larger living-dining. We draw both against your actual plan so the trade-off is visible before you commit.
Do you charge more for a non-standard size?
No. Pricing follows the material schedule and the running length of joinery, not the tidiness of the configuration. Bespoke carcass sizes cost the same to manufacture as standard ones, because everything is made to order anyway.
The builder's drawing does not match what was built. What now?
That is common, especially in redeveloped buildings and older stock. We measure the flat on site and redraw it. Designing off an inaccurate drawing is the single most expensive mistake in a fit-out — joinery ordered to a wrong dimension cannot be adjusted on site.
Can you work on a duplex or a house across floors?
Yes. The staircase and the service routing between levels are decided first, because they set the material and lighting strategy everywhere else. Each floor is drawn separately and checked against the others for continuity.
We are still building. When should interiors start?
Before the electrical and plumbing are closed. Deciding interiors while the structure is open is the cheapest moment to move a socket, a drain or a wall, and it removes almost all of the rework that a later fit-out creates.
What if I only know the super built-up area?
Send it and we will work backwards, but treat it as provisional. Carpet area is typically 60–75% of super built-up depending on the building, which is too wide a range to design against. The real number comes off the measurement.

Every surface has to do two jobs. The wins come from going vertical, keeping joinery the colour of the walls, and choosing furniture that folds, stacks or stores.

The most common Indian apartment, and the one where planning discipline pays off most. Storage volume and a workable kitchen triangle are the two decisions that matter.

Enough space for the rooms to have distinct characters while still sharing one material language. This is where a whole-home palette starts to genuinely pay off.

Scope for formal and informal zones to be genuinely separate. The design problem shifts from fitting things in to holding the scheme together across more rooms.

Multi-level planning, bespoke furniture and a longer programme. The coordination between joinery, stone, lighting and furniture becomes the main body of the work.
