How to Calculate a Realistic Interior Design Budget for 2BHK, 3BHK & 4BHK Homes

Why 'Per Square Foot' Quotes Are Misleading

Homeowners often ask: 'What is your rate per sq. ft.?' In reality, a 1500 sq. ft. 3BHK can cost ₹12 Lakhs or ₹45 Lakhs depending entirely on material specifications, hardware brands, and civil scope.

The 5 Core Budget Buckets

  1. Fixed Woodwork & Modular Joinery (45% - 50%): Kitchen cabinets, bedroom wardrobes, TV consoles, vanity counters, and study units.
  2. Civil & Structural Work (15% - 20%): Wall reconfigurations, bathroom tile changes, granite counter installation, plumbing, and damp treatment.
  3. Electrical & False Ceiling (12% - 15%): Wiring rerouting, MCB distribution, gypsum false ceiling, cove lighting, and architectural spotlights.
  4. Surfaces & Finishes (10% - 12%): Wall paint (luster/royal emulsion), PU coating on wooden paneling, wallpaper, and textured plaster.
  5. Loose Furniture & Soft Decor (15% - 20%): Sofas, dining chairs, rugs, sheer curtains, mattresses, and decorative light fixtures.

Realistic Benchmark Estimates (Kolkata Metro Standards)

  • Premium Standard (Core Plywood + Laminate): ₹1,200 – ₹1,600 per sq. ft. built-up area.
  • Luxury Contemporary (Acrylic/PU + Quartz + False Ceiling): ₹1,800 – ₹2,400 per sq. ft.
  • High-End Bespoke (Veneer/Duco + Italian Marble + Full Automation): ₹2,800 – ₹3,800+ per sq. ft.
Pro Tip: Always keep a 10% contingency fund for unforeseen site conditions, especially plumbing rerouting and concealed wall dampness discovered during demolition.
