“3 room cost” can mean either construction cost (building three rooms) or interior cost (designing/furnishing three rooms). The numbers differ a lot, so here’s both:
1. Construction Cost (Building 3 Rooms)
Assume average room size = 150 sq ft each → total 450 sq ft.
- Construction rates in Delhi NCR: ₹1,800 – ₹3,000 per sq ft
- 450 × 1,800 = ₹8.1 lakhs (basic build)
- 450 × 2,400 = ₹10.8 lakhs (mid finish)
- 450 × 3,000 = ₹13.5 lakhs (premium)
This includes walls, plaster, flooring, wiring, and paint (excluding land).
2. Interior Design / Furnishing Cost (3 Rooms)
Using per sq ft interior rates: ₹1,200 – ₹3,500+ per sq ft
- 450 × 1,200 = ₹5.4 lakhs (basic: paint, standard furniture, lights)
- 450 × 2,000 = ₹9 lakhs (mid: wardrobes, modular furniture, false ceiling)
- 450 × 3,500 = ₹15.7 lakhs (premium: veneer finishes, custom furniture, high-end lighting)
3. Example Breakdown (3 Bedrooms, Mid-range)
- Wardrobes: ₹2–3 lakhs total
- Beds + side tables: ₹2–3 lakhs total
- False ceiling + lighting: ₹1–1.5 lakhs
- Painting / wall finishes: ₹1–1.5 lakhs
- Curtains, décor, furnishings: ₹1–2 lakhs
👉 Approx total = ₹8–10 lakhs for mid-quality interiors of 3 rooms.
✅ Rule of Thumb
- New build (3 rooms): ₹8–13.5 lakhs
- Interiors (3 rooms): ₹5.4–15.7 lakhs
