15×40 site in Bangalore – realistic construction cost for G vs G+1?
Hey everyone,
I am a middle class guy. Trying to construct a decent house.
The plan is to build on a 15×40 (600 sq ft) plot in Bangalore. Trying to decide between G only vs G+1, depending on budget.
### My rough estimate (please sanity check)
- G (≈500 sq ft): ₹10–15L
- G+1 (≈1000 sq ft): ₹22–35L
(Assuming ₹2k/sq ft) Correct me if am wrong and give me some tips to lower cost here.
### What I want clarity on
- Hidden costs: approvals, borewell, BESCOM, interiors, compound wall, etc — how much extra % realistically?
- Is it smarter to:
- Build only G now but design for future floors, or
- Go G+1 directly?
- Contractor vs turnkey — what actually works better in Bangalore?
And again some tips to lower cost and get a decent house.
### Goal
Avoid budget blowing up mid-project and poor quality work.
Would appreciate recent real numbers + mistakes to avoid. Thanks!
