Kolkata Flat Interior Cost Guide 2026: Real Per Sq. Ft. Rates for 2 & 3 BHK Turnkey
A transparent itemized breakdown of interior costs across Kolkata (New Town, Ballygunge, EM Bypass) from civil prep to modular kitchens and 2700K lighting.
Calculating an accurate interior budget in Kolkata is notoriously tricky because local contractors often quote low lump sums, only to hit homeowners with 35% in unexpected 'extra work' bills midway through the project.
In reality, a quality turnkey interior in Kolkata ranges between ₹1,400 to ₹2,400 per square foot of carpet area for complete factory-finished joinery, BWP marine ply modular kitchens, and branded soft-close hardware.
For a standard 1,200 sq. ft. 3 BHK, a realistic premium budget sits between ₹18 Lakhs to ₹28 Lakhs. Deco Perfect locks this pricing upfront with a zero-cost-overrun fixed BOQ commitment.
