Interior requirement brief and site measurement in Kerala
An interior priced on unverified dimensions is priced on fiction. Two anchors here: what your household actually needs - counted, not assumed - and what the rooms actually measure.
The checks at this stage (5)
- Requirement brief written down
Household size, cooking style, the appliance list with dimensions, and a counted storage inventory - your actual clothes, vessels and books. The design is reviewed against this brief, not a catalogue. Unwritten needs are the ones the design misses.
- Rooms measured and verified
Laser-measured as-built dimensions: wall lengths, heights, diagonals, beam drops, existing points. Carcasses are cut to these numbers, not the floor plan - any gap between plan and reality becomes a visible gap or a rework at your cost.
- Base building readiness screened
Interiors interlock with the building: plaster done before measuring, flooring level coordinated with skirting, and - in older homes - wiring and plumbing age assessed before new finishes seal them in. Interfaces found late cost demolition.
- Appliance list locked with dimensions
Built-in appliances bought after carcass production is the classic retrofit disaster - the hob, oven, chimney and fridge dimensions drive the carcass cutting list. Lock the models, or at least the dimensions, before design freezes.
- Room-by-room unit list drafted
Walk every room against the full menu of units the Kerala market actually builds - the room-by-room menus are in this stage's standards - and mark each one in, out, or later. A unit that never made this list surfaces mid-execution as a change order at whatever rate the vendor names that day; one marked 'later' at least gets its electrical point and clearance planned now.
What good work looks like
What a real requirement brief contains
A brief the design can actually be tested against: household members and ages, cooking style, the appliance list with dimensions, and a counted storage inventory - hanging clothes, folded stacks, vessels, books. Wardrobe internals designed against counts fit; designed against guesses, they overflow in a year.
- Appliances listed with model or at least dimensions
- Storage counted in numbers, not described in words
- Every household member's needs appearing somewhere
- A brief that is a mood board with no counts
- Appliance choices deferred to after production
- Needs living in conversation instead of on paper
What a measurement sheet must show
A usable measurement record shows every room's wall lengths, height, both diagonals, beam drops and column projections, and the positions of existing points and openings - taken with a laser after plaster. Equal diagonals mean a square room; unequal ones mean carcasses planned for the room that exists.
- Every room with lengths, height and both diagonals
- Beam drops and projections dimensioned, not sketched
- Existing points and openings positioned on the sheet
- Measurements lifted from the floor plan instead of the site
- Diagonals missing - squareness assumed
- One height per room where the ceiling actually varies
The base-building interface list
On paper, before design: which building items interlock with the interior - plaster before measurement, floor level versus skirting, who owns which electrical points across two contracts, and in older homes the age of wiring and plumbing about to be sealed behind new finishes. Interfaces found late cost demolition.
- Each interface named with which side owns it
- Point ownership reconciled across both contracts
- Wiring and plumbing age noted before sealing them in
- The same points appearing in both scopes, twice
- Interior started before plaster settled the dimensions
- Old plumbing sealed behind new finishes unassessed
Kitchen — the full unit menu
Kerala kitchen quotes decompose into carcass units priced per square foot and accessories priced per piece. Walk the list; every unit you skip here is one a vendor can later add at an unbenchmarked rate.
- Bottom (base) unit and top (wall) unit — the core run
- Loft above the wall units
- Tall unit / crockery unit / mid-height cabinet
- Work-area units — base, overhead, and tall (the Kerala work kitchen is quoted separately from the show kitchen)
- Breakfast counter, oven unit, fridge unit, open shelves
- Store room base, overhead and tall units where a store exists
- Accessories counted per piece: soft-close drawers (80mm/185mm), tandem boxes, pot-and-pan pullouts, cutlery tray, glass plate rack, spice pullout, slim oil pullout, waste-bin pullout, SS304 detergent holder, dish drainer, anti-skid matting
- The work area assumed 'included' in the kitchen rate and billed separately later
- Accessories listed as 'included' without counts — then counted at handover
- Loft omitted from the quote and added mid-execution at a premium

Bedrooms — the full unit menu
Per bedroom, decide each of these in or out. The wardrobe is never the whole bedroom scope.
- Wardrobe (swing or sliding) and the loft above it
- Headboard — panelled or upholstered — and fluted panelling
- Dressing unit, freestanding mirror unit
- Cot (king/queen), cot side drawers, pedestal drawers
- Storage console and open shelves
- Loft quoted separately from the wardrobe without saying so — the two look merged until the bill
- Cot and side units assumed in scope because they appeared in the 3D render

Living, dining and loose furniture — the full unit menu
Fixed units and loose furniture are different trades at different rates — mark which of these you want built, which bought, and which skipped.
- TV unit, wall panelling, ceiling panelling
- Sofas (2/3/5-seater — built or solid wood), centre table, arm chairs, bench, bar stools
- Dining table and chairs — built-in laminate work versus solid wood are quoted on different bases (per sqft versus lump sum)
- Study table, study drawer unit, book shelf, side tables
- Pooja unit
- Loose furniture priced as lump sums slipped in beside per-sqft units so the totals cannot be compared line by line
- Solid-wood pieces quoted without wood species or section sizes

Other areas — the units everyone forgets
These are the lines that appear in finished Kerala homes but vanish from first-round quotes. Deciding them now is what keeps the comparison at IP3 honest.
- Wash-counter unit and LED mirror / plain mirror
- Shoe rack, gypsum or panelled false ceiling, partitions
- Stair-side storage unit, toilet box-up (pipe boxing), planter boxes
- Bar unit, bay-window seat and panelling, architrave panelling
- Outdoor pieces — arm chairs, centre table — if the sit-out is in scope
- Wash unit left out of every first quote and negotiated separately at a worse rate
- Toilet box-up and false ceiling drifting between the interior scope and the civil contractor's scope, billed by both

What a typical scope looks like, by home size
Observed full-home scopes, as a completeness cross-check — not a prescription. If your list is missing something below, the omission should be a decision, not an oversight.
- 2BHK (~800–1200 sqft): kitchen bottom + top + loft, bedroom wardrobes + lofts, TV unit, wash unit, shoe rack
- 3BHK (~1200–1800 sqft): the 2BHK set plus kitchen tall + crockery units, dressing units, headboards, wall panelling, study table, gypsum ceiling
- 4BHK / villa (~2000–3500 sqft): the 3BHK set plus breakfast counter, king cot, 5-seater sofa, pooja unit, dining set, bar unit
- A quote that covers fewer rooms than the home has, so the missing rooms return as 'phase 2' at fresh mobilization cost

Red flags and money traps
Factory panels are cut to the measured room - wall lengths, heights, diagonals, beam drops. Any gap between plan and reality becomes a visible gap in your kitchen or a rework at your cost. Measure after plaster, with a laser.
Insist on: A measurement sheet with both diagonals of every room - squareness is never assumed.
In a home with a building contract, some electrical and plumbing points may already be included in interior rooms. The same points billed in both scopes is the classic overlap - and only the owner reads both papers.
Reconcile: Point ownership across both contracts, on paper, before the interior scope is priced.
