“Cheap” interior design for a penthouse will still cost significantly due to scale, ceiling height, finishes, and complexity. Here’s a rough guide + sample numbers + factors to adjust.
Guiding Estimate Range
- On the low side, you might see ₹ 200 to ₹ 400 / sq ft for penthouse interiors with very basic finishes and minimal custom work.
- If you include better materials, more built-ins, lighting, etc., cost may rise to ₹ 500 to ₹ 800 / sq ft or more.
- High end or luxury penthouses often command many times that for premium finishes, but that’s beyond “cheap” scope.
Factors That Push Cost in a Penthouse
- Extra height / double volume areas
- Large windows / glass walls needing special treatments
- Roof terraces / terraces adjoining penthouse
- Specialized finishes (stone, wood, glass)
- More HVAC, insulation, waterproofing
- More lighting, circuits, ambience control
- Designer supervision & site logistics
Sample Calculation
Suppose your penthouse is 2,500 sq ft (usable interior):
- If done cheaply at ₹ 250 / sq ft → ₹ 6,25,000
- Add for lighting, electrical, modest carpentry, margin → + ₹ 1,50,000
- Total ~ ₹ 7,75,000
If you push finishes a bit: at ₹ 500 / sq ft → 2,500 × 500 = ₹ 12,50,000, plus extras.
If you tell me your city, penthouse area (sq ft or dimensions), and what level of finishes / features you want (just basics / wardrobe / lighting / glass work etc.), I can produce a more precise “cheap interior” quote for your penthouse. Do you want me to do that for yours?
