Carpet Area Efficiency: What South Mumbai Luxury Homebuyers Must Verify Before Booking

When investing in a ₹3 Cr to ₹20 Cr+ residence in South Mumbai, gross built-up area figures can be misleading. Certified usable carpet area analysis ensures you pay strictly for net usable space. Institutional developers like Godrej Properties, Piramal Realty, Sattva, and Prestige maintain 68% to 75% carpet efficiency. Always demand RERA-verified floor plans before signing an allotment letter.
