A 30×40 ft plot is 1,200 sq.ft — the most common independent-house site in Bangalore. Turnkey construction cost ranges from about ₹13.3 lakh for a compact ground-floor house to ₹1.12 crore for a G+3 rental building, driven mainly by the number of floors and the package (₹1,659–₹2,549/sq.ft, GST included). Configuration-wise costs, duplex and rental options, setbacks, timeline and FAQs are below. For the city-wide picture see construction cost in Bangalore or use the construction cost calculator.
30×40 Plot = 1,200 Sq Ft: What It Means for Cost
A 30×40 ft plot measures 1,200 sq.ft. After BBMP/BDA setbacks (front, rear and sides), the ground-floor footprint on a typical 30×40 works out to roughly 850–1,000 sq.ft, and our calculator uses about 960 sq.ft of built-up area per floor as a planning figure. Upper floors can be slightly larger where projections and balconies are allowed.
Construction is costed on built-up area × package rate, so the two levers that move a 30×40 budget most are the number of floors and the package (₹1,659–₹2,549/sq.ft, GST included).
Setbacks vary with road width, plot depth and the approving authority. The sanctioned plan gives the exact footprint; this is a planning sketch, not a design.
30×40 Construction Cost by Configuration
| Configuration | Approx. Built-up Area | Estimated Cost Range (incl. GST) | Typical Use |
|---|---|---|---|
| Ground floor only | 850–1,000 sq.ft | ₹13.3 lakh – ₹25.5 lakh | Compact single-family home, elderly-friendly |
| G+1 house | 1,800–2,200 sq.ft | ₹29.9 lakh – ₹56.1 lakh | Standard family home |
| G+1 duplex | 1,800–2,200 sq.ft | ₹29.9 lakh – ₹56.1 lakh | Single family, internal staircase, double-height living |
| G+2 (owner + rental) | 2,700–3,300 sq.ft | ₹44.8 lakh – ₹84.1 lakh | Own floor + 1–2 rental units |
| G+3 rental building | 3,600–4,400 sq.ft | ₹59.7 lakh – ₹1.12 crore | Rental income focus (check FAR/approval) |

30×40 G+1 Cost — Package by Package
Using ~2,000 sq.ft built-up for a 30×40 G+1:
| Package | Rate / Sq Ft | Approx. Cost (2,000 sq.ft) |
|---|---|---|
| Value Home | ₹1,659 | ₹33.2 lakh |
| Dream Home | ₹1,999 | ₹40.0 lakh |
| Premium Home | ₹2,159 | ₹43.2 lakh |
| Legacy Home | ₹2,549 | ₹51.0 lakh |
Adjust for your actual built-up area and add secondary areas (parking, balcony) at ~80% of the rate. Full specification comparison: house construction packages in Bangalore.
30×40 Duplex House Cost in Bangalore
A 30×40 duplex is usually a G+1 (sometimes G+2) built for a single family with an internal staircase, and often a double-height living or pooja space. The built-up area and therefore the cost are close to a 30×40 G+1 house — roughly ₹29.9 lakh to ₹56.1 lakh for civil construction across packages — with a modest premium if you add a designed elevation, a taller void, or upgraded railings and flooring. Duplex layouts are typically built on the Premium Home package for the higher ceiling height.
30×40 Rental Building Configuration
For rental income on a 30×40, owners usually build G+2 or G+3 with one or two units per floor (1BHK / 2BHK). Key planning points: a single well-placed staircase to maximise rentable area, stilt or ground parking sized to the number of units, separate electrical meters, adequate water storage, and compliance with the applicable FAR/FSI and parking norms for the plot. Cost scales with total built-up area — see the configuration table above.
Setbacks, Parking & Floor Plan Possibilities
- Setbacks: a 30×40 typically needs front, rear and side setbacks per the sanctioned plan; exact figures depend on road width, plot depth and the approving authority (BBMP / BDA / BMRDA / Panchayat).
- Ground-floor footprint: after setbacks, usually ~850–1,000 sq.ft usable.
- Parking: plan ~180 sq.ft per car and ~40 sq.ft per two-wheeler; stilt parking keeps the ground floor open for rental units.
- Typical GF layout: living, kitchen, one bedroom with bath, staircase, utility; parking in the front setback / stilt.
- Typical upper floor: 2–3 bedrooms with baths, family space, balconies within permissible projection.
- Staircase: position it to keep rooms regular and reduce circulation loss — important on a 30 ft frontage.

30×40 Construction Timeline
| Stage | Indicative Duration |
|---|---|
| Design, drawings & approval | 4–10 weeks (approval varies by authority) |
| Foundation & plinth | 3–5 weeks |
| Superstructure (per floor) | 5–7 weeks per floor |
| Masonry, plastering, waterproofing | 4–6 weeks |
| Flooring, doors, windows, painting, finishing | 8–12 weeks |
A 30×40 G+1 typically takes about 7–10 months from start of site work to handover, subject to approvals, design finalisation, weather and material selection.
