This page is focused on Karnataka house construction cost. Use it for a realistic starting estimate for Bengaluru / Mysuru / Mangaluru / Hubballi and other towns by choosing city type, floors and finish level.
Not a quotation. Use this to talk to your architect / engineer / contractor.
Karnataka spans Bengaluru's premium tech corridors, coastal Mangaluru and drier interior districts, so rates vary widely. Bengaluru leans towards mid-to-premium finishes and has higher labour costs.
Much of the state has hard granite or rocky strata, which can raise excavation and foundation costs but gives strong bearing. Coastal Karnataka (Mangaluru, Udupi) needs serious waterproofing against heavy monsoon and salt air.
Quick tip: In Bengaluru, confirm a contractor rate using the custom-rate option — real quotes often run above generic estimates.
