A 12×12 ft room = 144 sq ft. The cost depends on whether you mean:
- Building a new room (construction) → walls, roof, floor, wiring, doors, windows.
- Interior design of an existing room → furniture, finishes, décor.
1. Construction Cost (New Room)
Average construction cost in India (Delhi NCR benchmark): ₹1,800–₹3,000 per sq ft.
- 144 sq ft × ₹1,800 = ₹2.6 lakhs (basic build)
- 144 sq ft × ₹2,400 = ₹3.5 lakhs (mid finish)
- 144 sq ft × ₹3,000 = ₹4.3 lakhs (premium)
This covers structure, flooring, plaster, basic electrical, and paint. Premium finishes (marble, designer windows, false ceiling) push costs higher.
2. Interior Design Cost (Furnishing an Existing Room)
Typical cost per sq ft for interiors: ₹1,200–₹3,500+ per sq ft.
- 144 sq ft × ₹1,200 = ₹1.7 lakhs (basic: paint, standard furniture, lights)
- 144 sq ft × ₹2,000 = ₹2.9 lakhs (mid: modular wardrobe, better furniture, false ceiling)
- 144 sq ft × ₹3,500 = ₹5 lakhs (premium: veneer finishes, custom furniture, high-end lighting)
3. Cost Breakdown Example (Bedroom, 12×12 ft)
- Wardrobe: ₹70,000 – ₹1.5 lakhs
- Bed + side tables: ₹50,000 – ₹1 lakh
- False ceiling + lighting: ₹30,000 – ₹70,000
- Flooring / wall finishes: ₹40,000 – ₹1 lakh
- Décor & furnishings: ₹30,000 – ₹80,000
👉 Total: ₹2–4 lakhs depending on quality.
✅ Quick Rule:
- New build: ₹2.6–4.3 lakhs
- Interior only: ₹1.7–5 lakhs
