Common plot sizes in Kolkata

Most of the Kolkata plots we design for fall in these sizes:

• 2 cottah (approx 1,440 sq ft)
• 3 cottah (approx 2,160 sq ft)
• 4 cottah (approx 2,880 sq ft)
• 5 cottah (approx 3,600 sq ft)

Browse 30x40 plans, 30x50 plans or 40x60 plans to see what fits, or go by 3 BHK layouts.

Climate and orientation

Humid with long sticky summers, a heavy monsoon and occasional cyclones, plus a short pleasant winter. Verandahs, high ceilings and damp-proofing are old Bengal wisdom. We also check the plot facing early, because Vastu placement and sun path have to be solved together.

Soil and structure

Soft Gangetic alluvium and clay with a shallow water table, so pile or raft foundations are routine even for small houses. Our structural engineer sizes footings and columns from the soil report, which is why we ask for a soil test before the working drawings are issued.

Approvals in Kolkata

Plans are sanctioned by Kolkata Municipal Corporation (KMC) and KMDA. KMC building rules typically allow G+2 to G+3 on small plots with FAR and setbacks depending on plot area and road width, and New Town plots follow HIDCO guidelines. We draw to those setbacks and ground coverage limits from the first sketch, so the sanction drawing and the design are the same drawing.

Construction cost in Kolkata (2026)

Expect roughly Rs 2,000 to Rs 3,200 per sq ft for an independent house, labour and material, excluding land. Standard finishes sit at the lower end; stone elevations, premium flooring and modular interiors push it to the top. Try the construction cost calculator for your plot, or read how construction cost per sq ft breaks down.

What gets built in Kolkata

Narrow-plot G+2 and G+3 homes with cantilevered balconies and grilled verandahs, with contemporary white villas in New Town plots. See elevation design for the styles we draw most.
