What you need before you start
- Plot length and width in feet, from your sale deed, patta, or a measurement taken on site.
- Your local setback requirement. This is usually printed on your approved building plan, or available from your Panchayat, Municipality or CMDA/DTCP office.
- The number of floors you are planning to build.
- A build quality in mind, or a rate per square foot already quoted by a contractor.
Example: a 30 × 40 ft plot
Allow a 2 ft setback on every side, so 4 ft comes off both length and width.
36 × 26 ft (40 minus 4, by 30 minus 4) gives the ground floor area.
How much area do you need
Plan by your needs
List what you want in the house first.
A two-bedroom home with attached toilets, parking, an open kitchen, a pooja room and one common toilet takes about 900 sq ft. Share a similar list with your construction company to get an exact area for your plan.
Plan by your budget
Divide your construction budget by your rate per sq ft.
Say you have ₹37 lakh in total and set aside some for other expenses, leaving ₹30 lakh for construction. At the Standard rate of ₹2,400 per sq ft: ₹30,00,000 ÷ 2,400 = 1,250 sq ft.
Frequently asked questions
How do you calculate house construction cost per square foot?
Multiply your built-up area in square feet by the construction rate per square foot for the quality you want. A 1,200 sq ft house at the Standard rate of ₹2,400 per sq ft costs about ₹28.8 lakh. The calculator above does this for you.
What is a good house construction cost per square foot in India?
Rates typically run from about ₹2,200 to ₹3,500 per sq ft, depending on city, materials and finish level. Standard builds sit near the lower end and Luxury at the top. See our residential construction cost per sq ft guide for what changes the price.
What is built-up area, and how is it different from plot area?
Plot area is the full size of your land. Built-up area is the floor space you actually construct, after the required setback is removed from each side. Built-up area is always smaller than plot area, and it is the figure used to calculate construction cost.
What is a setback, and why does it reduce my house size?
A setback is the open space your local planning authority requires between your plot boundary and your building wall, usually 2 to 5 ft per side depending on plot size and local rules. It is meant for light, ventilation and access, and it reduces the area you can actually build on.
Does this calculator include the full house construction budget?
No. It estimates construction cost only, which is built-up area multiplied by rate per sq ft. Your full budget also needs EB connection, borewell, government approvals and other charges. Use the House Construction Budget Calculator for the complete picture.
How much land do I need to build a 1,000 sq ft house?
It depends on your setback requirement. With a 2 ft setback on all four sides, you would need a plot slightly larger than 1,000 sq ft after adjusting for shape. Use the plot to built-up area tool above with your own dimensions for an exact number.
