Understanding Carpet Area vs. Built-Up Area: What Pune Buyers Should Know
Carpet area refers to the actual usable floor space inside a home, while built-up area includes the carpet area plus walls and utility spaces. For Pune homebuyers comparing 3 BHK or 4 BHK flats, knowing these differences ensures accurate property valuation and smarter investment decisions.
For most homebuyers in Pune, the first question after shortlisting a property is — “How much space am I actually getting?”
That’s where the concepts of carpet area, built-up area, and super built-up area come into play. These terms may sound technical, but understanding them can save you lakhs of rupees and help you accurately compare 3 BHK and 4 BHK flats in Pune before making a final investment.
Let’s break it down clearly and see what every Pune homebuyer must know.
What Is Carpet Area and Why It Matters for Pune Homebuyers?
Carpet area is the actual usable floor area within the inner walls of your flat — the space you can literally cover with a carpet.
It includes:
- Bedrooms, living room, kitchen, and bathrooms
- Internal passages and staircases within your apartment
It excludes:
- Thickness of inner or outer walls
- Common areas like lobbies, elevators, staircases
Why It’s Important
In Pune, property pricing is often quoted per sq. ft. of carpet area (as per RERA norms). This makes it the most accurate measure of livable space.
Example: If a 3 BHK flat in Kharadi has a carpet area of 1,000 sq. ft. and the price is ₹10,000 per sq. ft., your cost = ₹1 crore.
Tip: Always confirm that the carpet area mentioned in your agreement matches the RERA-approved plan.
What Is Built-Up Area and How Is It Calculated?
Built-up area = Carpet area + thickness of walls + balcony + terrace + utility area.
On average, the built-up area is 10–15% larger than the carpet area.
Example: If the carpet area is 1,000 sq. ft., the built-up area might be around 1,150 sq. ft.
Why It Matters
Many developers in Pune earlier quoted prices based on built-up area, which inflated the cost per square foot.
Now, with RERA regulation, most reputed builders like Kolte Patil Developers provide transparent carpet-area-based pricing.
What Is Super Built-Up Area?
Super built-up area (also called “saleable area”) includes:
- Built-up area + proportionate share of common areas (staircase, lifts, lobby, clubhouse, garden, corridors, etc.)
Formula
Super Built-Up Area = Built-Up Area + Common Area Share
This figure is usually 25–30% more than the carpet area.
Example: If carpet = 1,000 sq. ft. → super built-up = ~1,300 sq. ft.
Buyer Insight
A super built-up area gives you a sense of the overall space you pay for, but not all of it is usable. For accurate comparisons between flats for sale in Pune, always rely on carpet area.

Why Understanding Property Measurements Is Crucial in Pune Real Estate
1. Accurate Valuation
Knowing the difference between carpet and built-up area helps determine the true cost per sq. ft. and prevents overpaying for non-usable space.
2. Transparency Under RERA
RERA mandates all builders in Pune to sell properties based on carpet area only, ensuring uniformity and fairness.
3. Smarter Property Comparison
Buyers can now accurately compare 3 BHK homes in Kharadi, 4 BHK flats in Baner, or premium township residences near Hinjewadi — apples to apples.
4. Better Negotiation Power
When you understand property measurement terms, you can confidently negotiate with developers or agents who still quote “built-up” figures.
What Are the Legal Implications of Carpet Area in Pune?

- As per Section 2(k) of RERA (Real Estate Regulation Act), “carpet area” is legally defined as the net usable floor area within the apartment walls.
- Pune developers must register every project under RERA and declare carpet area for every unit type.
