Quick Answer:
What does the per square foot construction rate include? A standard turnkey construction rate (e.g., ₹2,100 per sq.ft) includes all civil construction materials and labor required to build the habitable structure. This generally covers the foundation (up to 5 ft), RCC framing, brickwork, plastering, standard flooring tiles, basic electrical wiring, plumbing pipes, bathroom fixtures, and interior/exterior painting. It typically excludes compound walls, borewells, government approval fees, and interior woodwork (wardrobes/modular kitchens).
When you start researching how to build a house, the first metric you encounter is the "Per Square Foot (Sq.Ft) Rate." It seems wonderfully simple. If your house is 2,000 sq.ft and the rate is ₹2,000, your total budget is ₹40 Lakhs, right?
Unfortunately, it is never that simple.
The per sq.ft rate is the most misunderstood number in the Indian real estate market. Because there is no standardized legal definition of what must be included, different contractors include entirely different things. A quote of ₹1,800/sq.ft from Contractor A might ultimately cost you more than a quote of ₹2,200/sq.ft from Contractor B.
To help you compare quotes accurately, we are breaking down exactly what is (and isn't) included in a standard house construction cost in Bangalore.

1. What Does "Square Foot" Actually Refer To?
Before you can understand the cost, you must understand the multiplier. When builders quote a per sq.ft rate, they are referring to the Built-Up Area, not the Plot Area or the Carpet Area.
- Plot Area: The total size of your land (e.g., 30x40 = 1,200 sq.ft).
- Carpet Area: The usable floor area inside the house where you can literally lay a carpet.
- Built-Up Area (Slab Area): The total area covered by the concrete roof slabs across all floors, measured from the outer edges of the exterior walls. This includes the walls themselves, balconies, and staircases.
If you build a Ground + 1 Floor house on a 1,200 sq.ft plot, and each floor's slab covers 800 sq.ft, your total Built-Up Area is 1,600 sq.ft. The contractor will multiply their rate by 1,600, not 1,200.
2. Standard Inclusions (The Basics)
When you sign a comprehensive turnkey construction package, the following items are universally expected to be included in the per sq.ft rate:
Structural & Civil Work
- Foundation: Earthwork excavation (usually up to 5 feet deep), PCC, footings, and plinth beams.
- RCC Framing: Columns, beams, and roof slabs using specified grades of TMT Steel and Cement.
- Masonry: Solid blocks, AAC blocks, or red bricks for external and internal walls.
- Plastering: Cement plastering for inner walls, outer walls, and ceilings.
Finishing Work
- Flooring & Tiling: Floor tiles/granite for the living areas and bedrooms, plus anti-skid tiles for bathrooms and balconies. Wall cladding for bathrooms up to 7 feet.
- Painting: Wall putty, primer, and two coats of interior emulsion. Exterior weather-proof paint for the outside.
- Doors & Windows: The main door frame and shutter (often Teak or engineered wood), internal flush doors, and UPVC or aluminum sliding windows.
MEP (Mechanical, Electrical, Plumbing)
- Electrical: Concealed PVC conduits, fire-retardant copper wiring, distribution boards, MCBs, and modular switches.
- Plumbing: CPVC pipes for hot/cold water, PVC pipes for drainage, an overhead water tank (e.g., 1000L Sintex), and standard CP & Sanitary fittings (taps, commodes, washbasins).
3. Understanding the "Allowance" System
This is where quotes drastically differ. When a builder includes "Flooring" in their rate, what kind of flooring are they giving you? Italian marble or cheap ceramic tiles?
Reputable builders use an "allowance" or "budget limit" system. Their detailed Bill of Quantities (BOQ) will state:
"Living Room Flooring: Vitrified Tiles provided with an allowance of ₹80 per sq.ft."
This means you can visit the showroom and pick any tile up to ₹80/sq.ft, and it is fully covered. If you fall in love with a premium ₹120/sq.ft tile, you simply pay the contractor the ₹40 difference.
When reviewing what is included in turnkey home construction, always compare the allowances. A cheap quote usually hides painfully low allowances (e.g., ₹40/sq.ft for tiles), guaranteeing that you will have to pay out-of-pocket for upgrades later.
4. Standard Exclusions (What You Pay Extra For)
To avoid a mid-project financial crisis, you must budget for the items that are not covered by the built-up area multiplier. These are known as hidden costs.
| Common Exclusion | Why It Is Excluded | How It Is Billed |
|---|---|---|
| Compound Wall & Gate | It sits on the plot boundary, not under the roof slab. | Per Running Foot (RFT) + Lumpsum for the MS Gate. |
| Statutory Fees | Government BBMP/BDA plan approval and BESCOM deposits vary wildly by zone. | Direct payment to authorities or via architect/liaison. |
| Borewell Drilling | Water depth is unpredictable (300 ft vs 1000 ft). | Per foot drilling cost + casing + pump cost. |
| Deep Foundations | Standard quotes assume hard soil at 5ft. Loose soil requires deeper digging. | Extra steel/concrete billed at actuals. |
| Interior Woodwork | Wardrobes and modular kitchens are highly customized lifestyle choices. | Separate interior design contract. |
