The average cost of interior design for a 3BHK home depends on the level of finishes, quality of materials, and scope (basic fittings vs full turnkey execution). Based on common nationwide trends in major Indian cities:
📊 Average Cost Ranges
| Category | Typical Average Cost (₹) | What It Includes |
|---|---|---|
| Budget / Functional | ₹7 L – ₹10 L | Basic modular work, wardrobes, paint & lights |
| Mid-Range Average | ₹12 L – ₹18 L | Better finishes, coordinated design, false ceiling (select rooms), quality furniture |
| Premium / Designer | ₹20 L – ₹30 L+ | Custom furniture, high-end materials, full paraphernalia |
Key average range:
👉 ₹12 L – ₹18 L for a 3BHK is the realistic average cost most homeowners spend for balanced quality and good design.
📏 Per Sq Ft Average
Interior designers often price based on carpet area:
- Budget: ₹800 – ₹1,200 per sq ft
- Average: ₹1,500 – ₹2,000 per sq ft
- Premium: ₹2,500 – ₹4,000+ per sq ft
For a 1200–1400 sq ft 3BHK
- ₹1,500 × 1300 ≈ ₹19.5 L
- ₹2,000 × 1300 ≈ ₹26 L
However, because low and mid segments bring the overall average down, most completed 3BHK projects fall in the ₹12 L – ₹18 L band.
