## Direct answer

RERA carpet area is the net usable floor area within the apartment, including internal partition walls but excluding balconies/terraces (usually disclosed separately) and common-area shares. Built-up area typically adds external wall thickness to carpet area. Saleable (super built-up) area further loads a proportionate share of common areas like lobbies, corridors and clubs — which is why saleable figures look larger than carpet and vary between projects. Always compare carpet area and layout efficiency (carpet ÷ saleable), not headline saleable numbers alone, and match the definition to your Agreement for Sale annexure.

## Summary

Explains RERA carpet area, built-up area and saleable/super built-up area for a 3 BHK, why two projects quote different saleable figures for similar layouts, how to calculate layout efficiency, and what to verify in the agreement annexure.

## FAQs

**Q: Are balconies included in RERA carpet area?**

A: Generally no. Under the Real Estate (Regulation and Development) Act, 2016, carpet area refers to the net usable floor area within the apartment. Open balconies and terraces are usually disclosed separately in the agreement schedule and are not counted as carpet area unless a specific approved definition in your project documents states otherwise.

**Q: Are internal walls included in carpet area?**

A: RERA carpet area typically includes the area covered by internal partition walls within the apartment, measured to the internal finished surface. External wall thickness and common-area shares are not part of carpet area. Always match the definition on your Agreement for Sale annexure.

**Q: Why do two 3 BHK projects quote different saleable areas for similar layouts?**

A: Saleable or super built-up figures load different shares of common circulation, amenities, ducts and marketing conventions. Two towers with similar room counts can differ in corridor width, lift lobby size, balcony depth and loading factor. Compare carpet area and layout efficiency instead of headline saleable alone.

**Q: How should Ariva's 278 sq. yd. be described?**

A: Ariva markets approximately 278 sq. yd. as the unit or layout size — a buyer-facing planning dimension for the 3 BHK home. It is not a substitute for the RERA carpet area on your agreement. Request the registered carpet schedule and approved layout for the exact unit you plan to buy.

**Q: What is built-up area?**

A: Built-up area usually means carpet area plus the thickness of external walls and sometimes balcony slabs or other structural elements, depending on how the promoter defines it in marketing material. It is not the same as RERA carpet area unless explicitly stated.

**Q: What is saleable or super built-up area?**

A: Saleable area (often called super built-up in brochures) adds a proportionate share of common areas — lifts, lobbies, corridors, club, ducts — to the built-up or carpet base. This is why saleable numbers look larger than carpet and vary between projects.

**Q: How do I calculate layout efficiency?**

A: Divide RERA carpet area by saleable area (or the promoter's loaded area definition) and express as a percentage. Higher efficiency means more usable space per rupee of loaded area. Use the same denominator for both projects you compare.

**Q: What should I verify in the agreement annexure?**

A: Match unit number, tower, floor, RERA carpet area, balcony or terrace schedule, parking allotment, and room dimensions against the approved layout and GujRERA filing. Any verbal promise about size should appear in the registered agreement schedule before you pay a token.
