This page is focused on West Bengal house construction cost. Use it for a realistic starting estimate for Kolkata / Howrah / Durgapur / Siliguri and WB towns by selecting city type, floors and finish level.
Not a quotation. Use this to talk to your architect / engineer / contractor.
West Bengal's biggest cost driver is often the ground itself. Kolkata and the deltaic plains have soft alluvial soil and a high water table, so pile or raft foundations — and dewatering — can add significantly to budgets.
Kolkata costs more than Howrah, Durgapur, Siliguri or smaller towns. The humid climate makes waterproofing essential, while the North Bengal hills (Darjeeling, Kalimpong) bring their own terrain and access costs.
Quick tip: Get a soil test early in Kolkata and delta areas — foundation type can swing your budget more than finishes do.
