Building a House in Kolkata: What Affects the Cost
Approvals
Building plan sanction within city limits is from the Kolkata Municipal Corporation (KMC); areas outside the city fall under their own municipalities, with Salt Lake and New Town under their own development authorities.
Soil and foundation
Kolkata sits on soft alluvial soil with a high water table. Single-storey houses can often use isolated or raft foundations, but multi-storey buildings commonly need pile foundations. A soil test before design is strongly advised.
Climate
Hot, humid summers and heavy monsoon rain mean damp-proofing, good drainage around the plinth and raising the plinth in waterlogging-prone areas.
What people build
Independent G+1 and G+2 houses in the suburbs and small apartment buildings in the city are the most common new construction.
Tips to keep your Kolkata build on budget
- Budget for pile foundations if you plan more than two floors.
- Use a damp-proof course and raise the plinth in low-lying areas.
- Plan for monsoon delays in the construction schedule.
