Frequently asked

How much does a 3 BHK house plan cost in Chennai 2026?
Plan-only (2D + elevation + 3D) for a 3 BHK in Chennai: ₹18,000–₹45,000 (₹15–25 per sq ft of built area, for built area 1,200–1,800 sq ft). Full architectural with structural + CMDA-ready package: ₹78,000–₹2,30,000 (₹65–130 per sq ft). The full architectural package is required for CMDA filing; plan-only suffices if you have a builder ready and don't need formal approval.
What plot size do I need for a 3 BHK in Chennai?
Minimum practical plot: 1,200 sq ft (typically 30×40 ft) for a comfortable single-floor 3 BHK. Below this, room sizes get cramped. For comfortable spread with separate dining and utility: 1,500–2,000 sq ft. For luxurious 3 BHK: 2,000+ sq ft. CMDA setback rules apply — minimum 3m front, 1.5m side, 1.5m rear — which reduces buildable area.
Should I build 3 BHK single floor or G+1?
Single floor (1,500+ sq ft plot needed) — easier circulation, no stairs, lower construction cost per sq ft. G+1 (1,200+ sq ft plot works) — better land utilisation, vertical separation between formal living downstairs and private bedrooms upstairs, future flexibility (first floor as rental). Most Chennai families with plots 1,200–1,800 sq ft choose G+1 for these reasons.
Can I get a 3 BHK plan with separate dining and utility?
Yes, in plots 1,800+ sq ft. Below that, dining is usually open with living and utility is attached to kitchen. Separate dining adds 6'×8' to floor area; separate utility room adds 6'×6'. These are luxuries on smaller plots but standard on larger ones. Homeli's architects design layouts that maximise these on whatever plot you have.
What's vastu-compliant 3 BHK plan?
Vastu-friendly 3 BHK: master bedroom in south-west, kitchen south-east, entrance north or east, pooja north-east, living north or east, children's bedrooms south or west (avoid south-east). Three baths placement is critical — avoid north-east. Strict vastu often constrains layouts and CMDA setbacks; we balance both. See our /vastu-house-plan-chennai for direction-specific guidance.
How long does a 3 BHK design + approval take?
Design: 3–4 weeks (concept day 5, final plan week 2, full working drawings by week 4). Full architectural package: 5–6 weeks total. CMDA approval after that: 30–45 days. End-to-end design + approval: about 10–12 weeks. Construction (once approved) typically adds 10–12 months for a G+1 3 BHK.
