For a low-budget interior design of a penthouse in India, here’s a rough estimate range, influencing factors, and how to lower costs.
Estimate Range
- “Low-budget” interior might start from ₹ 200 to ₹ 400 per sq ft for the penthouse shell (basic finishes, minimal customization).
- If you include better finishes, modest custom cabinetry, lighting, etc., you might move toward ₹ 500 to ₹ 800 per sq ft.
- Higher end / luxury in penthouses often far exceed those, but those are outside “low budget.”
These are ballparks. Many sources cite general interiors being ₹ 250 to ₹ 500 / sq ft for standard work. (YF Decor)
Also note that in premium properties like penthouses, interior costs often are quoted as a percentage of property cost (e.g. 30-35%) for high end projects. (The Architects Diary)
Key Cost Drivers for Penthouse Interiors
- Ceiling height & volume: double-height spaces increase material need
- Terraces / open balconies attached to penthouse
- Full glazing / large windows (require special treatment)
- Custom carpentry / built-in furniture vs modular units
- Premium finishes (stone, imported tiles, wood, glass)
- HVAC, insulation, waterproofing (more critical at top floors)
- Lighting / electrical / smart systems
- Designer’s involvement / supervision / site visits
Example Scenario (Illustrative)
Say your penthouse internal area is ~2,000 sq ft, and you aim for minimal, functional finishes at ₹ 300 / sq ft:
- 2,000 × ₹ 300 = ₹ 6,00,000 (base finishes + minimal work)
- Add in lighting, fixtures, basic cabinetry, design fee, contingencies → maybe another 30-50% → ₹ 1,80,000 – ₹ 3,00,000
- Estimated total: ~ ₹ 7,80,000 to ₹ 9,00,000
If you push up finishes a bit, the cost could reach ₹ 10,00,000+ easily.
If you tell me your penthouse location (city), area in sq ft, and which elements you must include (terrace, glazing, custom furniture etc.), I can compute a more precise “low-budget” quote for your case. Do you want me to do that?
