Estimated Cost Range for a Small Flat
Assume your “small flat” is ~ 350 to 700 sq ft:
| Rate (₹ per sq ft) | Base Cost Estimate | With 10–15% Buffer |
|---|---|---|
| ₹800 | ₹2,80,000 – ₹5,60,000 | ~ ₹3,08,000 – ₹6,44,000 |
| ₹1,000 | ₹3,50,000 – ₹7,00,000 | ~ ₹3,85,000 – ₹8,05,000 |
| ₹1,200 | ₹4,20,000 – ₹8,40,000 | ~ ₹4,62,000 – ₹9,66,000 |
So a small flat interior on a budget may typically cost ₹3 lakhs to ₹7 lakhs depending on finishes, location, and scope.
