How a 20x30 site is priced
House construction is priced per square foot of built-up area, not plot area. On a 20x30 site about three quarters of the plot is usually built on each floor once setbacks are left open, so each floor adds roughly 450 sq ft. A G+1 house comes to about 900 sq ft; a G+2 to about 1,350, which is why most owners of a 20x30 site build up rather than settle for a single floor.
On a small plot the layout decides how much of that area you can actually use. A staircase, a car bay and setbacks take a bigger share of 600 sq ft than of a larger site, so the floor plan should be fixed before the budget is. The rates below are for construction only, and they move with the finish level you choose.

Construction only. Plan sanction and approval fees, GST, the compound wall, the borewell and loose furniture are separate. How many floors your own plot allows depends on its zone and the width of the road it faces; our guide to builder floors in Bangalore explains what to check before you design for height.
Why a range, not one number
Soil conditions, the structure your design needs and the brands you choose all move the final figure. That is why we don’t quote a lump sum over the phone. After a free visit to your plot, our team prepares a detailed bill of quantities that names every material, brand and quantity, and that BOQ locks your price in the contract.

20x30 cost questions
Is ₹20 lakh enough to build a house on a 20x30 site?
For construction alone, ₹20 lakh builds a ground-only house of about 450 sq ft on a 20x30 site at Basic, Standard, Premium or Ultra-luxury finish. A G+1 house (about 900 sq ft) also fits at Basic finish, from ₹15 lakh. Plan sanction fees, GST, the compound wall and the borewell are extra, so keep a margin above the build cost.
How much does a G+2 house on a 20x30 site cost in Bangalore?
A G+2 house on a 20x30 site has about 1,350 sq ft of built-up area. At our 2026 rates it costs ₹23 – 27 lakh at Basic finish, ₹27 – 35 lakh at Standard and ₹35 – 47 lakh at Premium, construction only.
How much built-up area do I get on a 20x30 site?
Plan on about three quarters of the plot per floor once setbacks are left open: about 450 sq ft for the ground floor, 900 sq ft for G+1 and 1,350 sq ft for G+2. The real figure depends on your plot’s zone, the road it faces and your floor plan; we confirm it before a plan is drawn.
What does a 20x30 site itself cost in Bangalore?
We build on plots our clients already own; we don’t sell land. Site prices in Bangalore vary widely by locality and by the plot’s khata and approvals, so recent sale prices in your own layout are the best guide. The figures on this page are for construction on the plot.
How much does a 600 sq ft house cost to build in Bangalore?
It depends on whether 600 sq ft is the plot or the house. A house with 600 sq ft of built-up area costs ₹10 – 12 lakh at Basic finish, ₹12 – 16 lakh at Standard and ₹16 – 21 lakh at Premium, construction only, at our 2026 rates. A 600 sq ft plot (20x30) usually takes about 450 sq ft per floor, so a G+1 house on it has about 900 sq ft of built-up area; the table above prices it floor by floor.
Does the price include approvals and GST?
No. The figures cover construction only. Plan sanction and approval fees, GST, the compound wall, the borewell and loose furniture are separate. Our team supports the approval paperwork, and every cost is listed in the BOQ before you sign.
