Renovation cost with bathrooms and the kitchen priced separately from the general area, because wet areas cost several times what a dry room does per square foot and averaging them across the flat hides the real driver.

₹14,49,000 for 1,200 square feet at the moderate scope, of which ₹1,89,000 is contingency. The general work is 1080000 at 900 a square foot for a moderate scope. Wet areas add 180000, which is 14% of the work before contingency, from a small fraction of the floor. Pricing them separately is what makes dropping one from the scope a decision the numbers can support. Contingency of 15% is higher than a new build would need, because opening up an existing structure finds problems rather than planning for them. Enter a rent figure if you will have to live elsewhere; six weeks is a real line item. Rates vary by city, season and contractor. Treat the figure as a budget with a stated contingency, not a quotation.

A single rate per square foot works badly for renovation because the cost is not spread evenly. A bathroom involves waterproofing, plumbing, tiling and fittings in a very small area, so it costs several times the per-foot rate of a bedroom, and a kitchen the same again. Pricing them separately makes the estimate both more accurate and more useful, since dropping one bathroom from the scope is a decision the numbers can now support. Renovation contingency runs higher than new build, fifteen to twenty percent, because opening up an existing structure reveals problems a new site does not have. Displacement is the cost people forget entirely: six weeks of rent elsewhere is a real line item.
general work scaled by scope, plus the wet areas priced separately because they cost several times the rate of a dry roomEach of these is asserted on every build. If a change to the engine ever moved one of these answers, the build would fail before the page could print it.
