You Are Buying the Carpet Area — Not the Super Built-Up Area
You see “1,200 sq ft” on a brochure and naturally imagine a spacious 1,200 sq ft apartment. But when you finally visit the flat, it somehow feels… smaller than expected.
That confusion usually comes from one thing: not understanding the difference between carpet area, built-up area, and super built-up area. Most buyers aren’t properly told what these terms actually mean.
You Are Buying the Carpet Area — Not the Super Built-Up Area
When you buy a flat, the only space that truly belongs to your daily living is the carpet area. That’s the space where you actually place your furniture, walk around, sleep, cook, and live your life. Everything else — outer walls, lobbies, staircases, lifts, corridors, amenities — adds to the total number you see in advertisements, but not necessarily to the usable space inside your home.
Once you understand this difference, property listings start making a lot more sense.
So what do these terms actually mean?
Carpet Area
Carpet area means the actual usable space inside your flat — inner walls, bedrooms, kitchen, living room, bathrooms. Basically, if you can walk on it and use it every day, it’s part of the carpet area.
This is your real living space.
Under MAHA RERA, this is also the legally recognised measurement for pricing and agreements.
Super Built-Up Area
This is where most first-time buyers get confused.
Super built-up area includes a proportionate share of common areas like: lobby, staircases, lifts, corridors and shared amenities.
So yes, you are paying for part of those spaces too.
That’s why super built-up area is usually 25–30% larger than the actual carpet area.
What this looks like in real life?
Let’s say a project advertises a flat as 1,200 sq ft. Sounds spacious. But in reality:
Actual carpet area may only be around 700 sq ft
Super Built-up area could be around 840 sq ft
The remaining area comes from common/shared spaces
Which means the space you actually live in is far smaller than the number you first saw in the ad.
This doesn’t mean the builder is necessarily misleading you. The problem usually comes from buyers comparing two properties using different measurements without realising it.
Why RERA changed this?
Before RERA, many projects were marketed mainly using super built-up area because the numbers looked bigger and more attractive. Today, projects in Maharashtra are required to advertise and sell properties based on carpet area defined by MAHA RERA.
That’s a huge improvement for buyers because it creates far more transparency.
It also means your Agreement for Sale should mention carpet area clearly, pricing is supposed to be based on usable space and if the final carpet area changes significantly at possession, buyers may be entitled to compensation.
