3BHK House Construction Cost (2026)
A 3BHK house costs about ₹20.3–33.9 lakh to build in 2026 (ground floor only, standard finish) at 1,100–1,500 sq ft of built-up area, or roughly ₹2,050 per sq ft with materials and labour. At 1,200 sq ft, the middle layout below, it is ₹22.2–27.1 lakh; as G+1 with 1,200 sq ft on each floor, ₹40.8–49.9 lakh.
SiteSetu cost engine, October 2026, at national-average prices. Includes materials, labour and 5% contingency; the range is ±10%. It is a budget, not a quote. Land, approval and design fees and interiors are extra.
In these three layouts a 3BHK takes 1,100 to 1,500 sq ft of built-up area. Beyond the third bedroom, the number of bathrooms, the dining space and the passages decide whether the extra area pays off.
3BHK cost: economy, standard and premium
For a ground-floor house, standard finishes work out to about ₹2,050 per sq ft, economy ₹1,750 and premium ₹2,550. Area means built-up area on each floor, walls included. G is ground only; G+1 is a new house with two equal floors. The figures come from the house cost calculator.
| Area per floor | Floors / total built-up | Economy | Standard | Premium |
|---|---|---|---|---|
| 1,100 sq ft | G / 1,100 sq ft | 17.5–21.4 | 20.3–24.8 | 25.3–31 |
| 1,100 sq ft | G+1 / 2,200 sq ft | 31.9–39 | 37.4–45.8 | 47.3–57.8 |
| 1,200 sq ft | G / 1,200 sq ft | 19.1–23.4 | 22.2–27.1 | 27.6–33.8 |
| 1,200 sq ft | G+1 / 2,400 sq ft | 34.8–42.6 | 40.8–49.9 | 51.5–63 |
| 1,500 sq ft | G / 1,500 sq ft | 23.9–29.2 | 27.7–33.9 | 34.5–42.2 |
| 1,500 sq ft | G+1 / 3,000 sq ft | 43.5–53.2 | 51.1–62.4 | 64.4–78.8 |
- Economy: Ceramic tiles, distemper, flush doors, basic fittings.
- Standard: Vitrified tiles, emulsion paint, branded fittings.
- Premium: Large-format tiles or granite, UPVC windows, premium fittings.
The structure is the same in all three; only finishes and services change. Basis: RCC frame on isolated footings, about 3 m floor height, brick walls and site-mixed concrete. Rates include contractor overheads and profit. No compound wall or sump.
Room-wise area options for a 3BHK
A 3BHK fits in 1,100–1,500 sq ft of built-up area in the three layouts below; the extra area goes into bathrooms, living space and utility.
These are area budgets, not drawings or minimum room sizes. Each table adds up to the built-up area; parking, garden and setbacks sit outside it. A G+1 house needs a new plan with a stair.
1,100 sq ft: Compact 3BHK: shared living space
| Space | Sq ft |
|---|---|
| Living and dining | 210 |
| Bedroom 1 | 130 |
| Bedroom 2 | 110 |
| Bedroom 3 | 100 |
| Kitchen | 90 |
| Two bathrooms together | 80 |
| Utility | 40 |
| Entrance and circulation | 140 |
| Walls and columns | 200 |
| Built-up total | 1,100 |
1,200 sq ft: 3BHK with two bathrooms
| Space | Sq ft |
|---|---|
| Living and dining | 240 |
| Bedroom 1 | 140 |
| Bedroom 2 | 120 |
| Bedroom 3 | 110 |
| Kitchen | 100 |
| Two bathrooms together | 90 |
| Utility | 45 |
| Entrance and circulation | 135 |
| Walls and columns | 220 |
| Built-up total | 1,200 |
1,500 sq ft: 3BHK with three bathrooms
| Space | Sq ft |
|---|---|
| Living and dining | 320 |
| Bedroom 1 | 170 |
| Bedroom 2 | 145 |
| Bedroom 3 | 135 |
| Kitchen | 125 |
| Three bathrooms together | 135 |
| Utility | 70 |
| Entrance and circulation | 150 |

| Built-up total | 1,500 |
Plot area, built-up area and the duplex ambiguity
Plot area is the land. Built-up area is what you build on each floor, walls included. The approved plan sets how much of the plot you can cover, so never multiply plot area by a construction rate.
The same 1,200 sq ft can be one floor or two. On one floor, a standard house costs ₹24,63,658 in the model; as two floors of 600 sq ft each, it costs ₹22,69,349. The difference comes from the smaller foundation and roof. The G+1 rows in the table above are different: they have 1,200 sq ft on each floor. Check that a smaller floor still fits your rooms before choosing it.
1,100 sq ft: protect circulation around the third bedroom
This option uses shared living/dining and two bathrooms. Draw doors and furniture together so the third bedroom does not become a route to another room. The area table is not a sanction-ready layout.
1,200 sq ft: compare a family home with rental use
The middle schedule keeps two bathrooms and a separate utility allowance. If all three bedrooms need attached bathrooms, revise the layout and count fittings before accepting the model budget. Bedroom count alone cannot price that requirement.
1,500 sq ft: a third bathroom and more shared space
The larger schedule includes three bathrooms and more living area. Compare wet-area specifications, external wall length and structural spans in the drawings. The engine scales generic quantities; these layout choices can change the measured quantities.
Material quantities at each planning size
At 1,200 sq ft, the middle layout, a ground-floor 3BHK needs about 549 bags of cement, 5,151 kg of steel and 10,078 bricks in this model. Finish quality does not change these quantities.
Cement covers RCC, PCC, brickwork and plaster; tile bedding is extra. Use these numbers to budget, not to order: an order list needs the structural drawings and a wastage allowance.
| Material | 1,100 sq ft · G | 1,100 per floor · G+1 | 1,200 sq ft · G | 1,200 per floor · G+1 | 1,500 sq ft · G | 1,500 per floor · G+1 |
|---|---|---|---|---|---|---|
| Cement (50 kg bags) | 503 | 873 | 549 | 952 | 686 | 1,191 |
| Reinforcement steel (kg) | 4,722 | 8,650 | 5,151 | 9,437 | 6,439 | 11,796 |
| Conventional bricks (nos) | 9,238 | 18,476 | 10,078 | 20,155 | 12,597 | 25,194 |
| Sand (cft) | 1,432 | 2,459 | 1,563 | 2,683 | 1,953 | 3,353 |
| Aggregate (cft) | 2,044 | 3,278 | 2,230 | 3,576 | 2,788 | 4,470 |
Sand and aggregate are in cubic feet (cft), not tonnes. Steel is the theoretical quantity; wastage is in its rate. These materials are already priced in the budget above, so do not add them again.
3BHK construction budget in eight cities
Local prices move the same 1,200 sq ft ground-floor house from ₹24.1 lakh in Hyderabad to ₹29.1 lakh in Mumbai, with standard finishes.
Only material prices and wages change between rows; the area is the middle layout. Each city guide lists its reported prices and their source dates. Coimbatore is not yet a city option in the calculator.
| City / source notes | G central total and range | G+1 central total and range (2,400 sq ft) |
|---|---|---|
| Bangalore | ₹27,92,407₹25.1 lakh to ₹30.7 lakh | ₹51,41,919₹46.3 lakh to ₹56.6 lakh |
| Chennai | ₹27,95,258₹25.2 lakh to ₹30.7 lakh | ₹51,56,643₹46.4 lakh to ₹56.7 lakh |
| Hyderabad | ₹24,14,452₹21.7 lakh to ₹26.6 lakh | ₹44,67,585₹40.2 lakh to ₹49.1 lakh |
| Pune | ₹27,83,852₹25.1 lakh to ₹30.6 lakh | ₹51,03,219₹45.9 lakh to ₹56.1 lakh |
| Mumbai | ₹29,06,795₹26.2 lakh to ₹32 lakh | ₹53,24,916₹47.9 lakh to ₹58.6 lakh |
| Delhi | ₹26,93,810₹24.2 lakh to ₹29.6 lakh | ₹49,38,532₹44.4 lakh to ₹54.3 lakh |
| Kolkata | ₹26,06,433₹23.5 lakh to ₹28.7 lakh | ₹47,85,306₹43.1 lakh to ₹52.6 lakh |
| Coimbatore | ₹26,07,461₹23.5 lakh to ₹28.7 lakh | ₹48,10,523₹43.3 lakh to ₹52.9 lakh |
The national figures on this page use the calculator's baseline: cement ₹390/bag, steel ₹56/kg, sand ₹55/cft, aggregate ₹40/cft, bricks ₹7,000/1,000 and mason ₹900/day. These are model inputs, not supplier quotes. Get delivered prices before ordering. Price review: August 2026 baseline; eight house-cost cities reviewed 20 October 2026 (source dates vary).
Stage-wise spend at 1,200 sq ft per floor
RCC frame takes the largest share, about 35.3% of a standard ground-floor budget; masonry and plaster is next at 12.6%. National-average prices.
| Stage | G amount | G share | G+1 amount |
|---|---|---|---|
| Foundation and plinth | ₹2,79,132 | 11.3% | ₹3,23,490 |
| RCC frame | ₹8,69,333 | 35.3% | ₹16,54,122 |
| Masonry and plaster | ₹3,09,873 | 12.6% | ₹6,19,746 |
| Flooring and tiling | ₹1,54,854 | 6.3% | ₹3,09,708 |
| Doors and windows | ₹1,89,000 | 7.7% | ₹3,78,000 |
| Painting | ₹1,07,822 | 4.4% | ₹2,15,644 |
| Electrical | ₹1,89,000 | 7.7% | ₹3,78,000 |
| Plumbing and sanitary | ₹2,14,200 | 8.7% | ₹4,28,400 |
| Waterproofing and misc | ₹1,50,444 | 6.1% | ₹2,31,588 |
| Total | ₹24,63,658 | 100% | ₹45,38,698 |
Each stage includes its share of the 5% contingency (G: subtotal ₹23,46,340.68 + 5% = ₹24,63,657.72). Rows are rounded to whole rupees so they add up to the total. RCC frame carries all steel and shuttering, footings included. These are cost groups, not a payment schedule: pay against measured, completed work.
What this budget includes and excludes
The budget covers the house from excavation to paint, with wiring, plumbing and sanitary fittings. Land, fees, interiors and special foundations are extra.
Included as model allowances
- Ordinary excavation, PCC, isolated footings, plinth filling and floor bed.
- RCC, reinforcement and formwork; conventional brick walls and internal/external plaster.
- Floor/wall tiles, doors, windows, paint, electrical, plumbing and sanitary allowances for the selected quality.
- Roof/wet-area waterproofing and a general kitchen-platform, railing and sundries allowance.
- Material and labour, the engine's overhead/profit allowances, and 5% contingency.
Price separately
- Land, authority fees, architect/structural design and utility connections.
- Basement, piles/raft, rock breaking, major dewatering and special retaining work.
- Furniture, wardrobes, modular kitchen and other fitted interiors.
- Borewell, lift, solar and external landscaping or paving.
- Compound wall and sump: available as calculator extras, but set to zero on this page.
Ask each contractor for quantities, units, rates and exclusions in writing. The 5% contingency covers small surprises, not an item you already know is missing.
Compare the model with a measured house BOQ
A measured BOQ will not match this model line for line: the model applies typical quantities to floor area, while a BOQ measures one set of drawings.
Our measured G+1 sample BOQ has 48 items from a different house. It is not a 3BHK benchmark and we do not scale it; the table only shows how the two methods differ.
| Quantity | This G+1 model | Published sample BOQ |
|---|---|---|
| RCC, m³ | 91.08 | 129.42 |
| Formwork, m² | 617.74 | 1,746.67 |
| Masonry, m³ | 40.8 | 111.38 |
The sample traces each quantity to the drawings and flags assumptions. Its rates are blank, it leaves out reinforcement, finishes and MEP, and its wall plaster is gross (before door and window deductions).
For your house, get a BOQ from your drawings. BOQ scope and price are confirmed after we see the drawings.
3BHK house construction cost FAQ
What is the 3BHK house construction cost in 2026?
About ₹20.3–33.9 lakh for a ground-floor 3BHK with standard finishes at 1,100–1,500 sq ft, or roughly ₹2,050 per sq ft with materials and labour at national-average prices. It is a budget with a 5% contingency and a ±10% range, not a contractor quote.
What does G+1 mean in this 3BHK comparison?
Two equal floors of 1,200 sq ft, 2,400 sq ft in total, at ₹40.8–49.9 lakh with standard finishes. It is not the same area split over two floors, and it does not price adding a floor to an existing house.
Is there one fixed built-up area for a 3BHK?
No. 3BHK is a room count, not a floor area. The layouts on this page are planning examples, not minimum sizes or approved plans. Their totals include walls, columns and circulation, but not open plot area.
How much cement and steel does a 1,200 sq ft house need?
About 549 bags of cement and 5,151 kg of steel for the ground-floor house. The cement covers RCC, PCC, brickwork and plaster; tile bedding is extra. Treat these as budget quantities, not an order list or a bar bending schedule.
Does a premium finish change the steel in a 3BHK house?
No. In this engine, finish choice changes tiles, doors, paint and services, not the structure: the 1,200 sq ft ground-floor house carries about 5,151 kg of steel at every finish level. A different column grid, span or soil needs a fresh calculation from drawings.
Are land, interiors and approval fees included in the 3BHK budget?
No. Land, authority and design fees, utility connections, furniture, wardrobes, modular kitchen, special foundations, basement, borewell, lift and solar are all extra. Compound wall and sump are set to zero here; add them in the calculator.
Why would a measured BOQ differ from this estimate?
A BOQ measures your drawings; this model applies typical quantities to floor area. Our published sample BOQ is a different G+1 house, with blank rates, no reinforcement, finishes or MEP, and gross wall plaster, so its quantities should not be scaled to this house.
Does another bathroom change a 3BHK budget?
Yes, even at the same built-up area: sanitary fittings, pipe runs, wall tiles and waterproofing all go up. The engine prices services by area, so it does not reprice an added bathroom; count it in the BOQ.
