Renovation calculator FAQ

Which renovation tier fits my 10-12 year old Chennai home?

Usually Tier 2 (Standard renovation, ₹650-1,500/sq ft) — kitchen + bathrooms + flooring + new wardrobes + paint + lighting. The modular furniture from 10-12 years ago is usually failing (MR plywood swollen, hardware sagging). Bathrooms + plumbing at this age also benefit from full replacement.

Should I renovate or tear down + rebuild?

Depends on home age + structural condition. Homes 30+ years old often need so much structural repair that tear-down + rebuild is more cost-effective than major renovation. Newer homes (under 25 years) almost always benefit more from renovation. Get a structural engineer's assessment before deciding for old homes.

How long does Chennai renovation take?

Cosmetic refresh: 2-3 weeks. Standard renovation: 6-10 weeks. Premium renovation: 10-14 weeks. Structural renovation: 16-24 weeks. Tear-down + rebuild: 12-18 months including approval.

Do I need CMDA / DTCP approval for renovation?

For Tier 1-3 (no structural change): no approval required. For Tier 4 (structural change — wall removal, extension, additional floor): yes, COA-registered architect's signed drawings + CMDA / DTCP approval needed. Approval filing adds 30-60 days to timeline.

Do I need to vacate my home during renovation?

For cosmetic refresh: possibly, but uncomfortable. For Tier 2+ involving kitchen/bathrooms/flooring: strongly recommend temporary relocation (4-12 weeks). Daily life becomes difficult without functional kitchen + bathroom.

What's NOT included in the calculator estimate?

Excluded: temporary accommodation (₹15-50k/month if relocating), packers-movers (₹15-40k), debris removal (₹10-25k), building approval fees (if Tier 4+ structural), electronic appliances, custom curtains, society/parking deposits. Budget 15-25% buffer.

Can I phase the renovation to spread cost?

Yes — phased renovation is common. Phase 1: kitchen + master bedroom (highest impact). Phase 2: living + dining + foyer. Phase 3: remaining bedrooms + bathrooms. Splits cash flow + allows partial-home occupancy. Adds 20-30% to total cost due to repeated mobilisation, but eases payment.
