Quick answer
M3M Forestia East I offers 3 BHK and 3.5 BHK apartments in Sectors M9, M10 and M11, Manesar, Gurugram. The published 3 BHK figure is a super built-up area of about 2,440 sq ft. Carpet area is lower, differs for every unit, and must be taken from the tower-wise plan. The Pocket B unit layouts are on the M3M Forestia East floor plans page.
Buying a home in a township like Gurugram International City (GIC) usually starts with one number: the size. But the number in a listing and the space you actually live in are two different things. This guide explains what the M3M Forestia East apartment sizes mean, how to read the unit plans, and which size suits which kind of household.
What Are the Apartment Sizes at M3M Forestia East?
M3M Forestia East I, developed by M3M India Infrastructures Pvt. Ltd., lists its 3 BHK at about 2,440 sq ft of super built-up area. That is saleable area, including your share of common spaces, not the floor area inside your walls. The 3.5 BHK size is shared on request.
| Configuration | Size basis | Published size | What to confirm |
|---|---|---|---|
| 3 BHK | Super built-up area | About 2,440 sq ft | RERA carpet area, balcony area, and which tower or pocket this figure applies to |
| 3.5 BHK | Super built-up area | Shared on request | Super built-up area, RERA carpet area and the dimensions of the extra half-room |
Treat 2,440 sq ft as the size you are billed for, not the size you can furnish. The next section explains the gap.
Super Built-Up Area vs Carpet Area vs RERA Carpet Area
Super built-up area is the carpet area plus balconies, wall thickness and a proportionate share of common areas like lobbies, lifts and staircases. Carpet area is the usable floor space inside the apartment. RERA carpet area is the legally defined version of that usable space, and it is the fairest number for comparing homes.
- Super built-up area: the total saleable area. It is always the largest of the three figures.
- Carpet area: the floor area you can actually lay a carpet on, inside the apartment walls.
- RERA carpet area: the net usable floor area, including internal walls but excluding external walls, service shafts, the exclusive balcony and any open terrace.
A worked example (hypothetical)
This example uses made-up numbers to show the method. They are not M3M Forestia East figures.
Suppose an apartment has a super built-up area of 2,000 sq ft and a RERA carpet area of 1,400 sq ft. Divide carpet by super: 1,400 ÷ 2,000 = 0.70, so the carpet-to-super ratio is 70%. The remaining 30% is balcony, walls and your share of common areas. Run the same sum on any unit you are considering, and compare ratios, not just headline sizes.
Questions to ask for the exact unit
- What is the RERA carpet area of this specific unit, in sq ft?
- What is the balcony area, and is it counted separately?
- What is the super built-up area on the same document?
- What is the loading, meaning the gap between carpet and super area?
- Is the figure for this tower and floor, or an average across the project?
How to Read an M3M Forestia East Floor Plan
To read a unit plan, work from the outside in: confirm which pocket, tower and unit it belongs to, find the entrance and orientation, then check each room’s dimensions, the balconies and utility space, and finally the shafts, columns and openings that limit how you can use the floor.
Identify the pocket, tower and unit number printed on the plan.
Confirm the unit type, 3 BHK or 3.5 BHK, and the area figure shown.
- Find the main entrance and the compass orientation.
- Read the bedroom and living room dimensions, not just the room labels.
- Locate balconies and the utility area, and check whether they have their own dimensions.
- Mark service shafts and structural columns. They reduce usable wall space.
- Check door and window positions, which decide furniture placement and light.
- Note the toilet locations and their distance from the kitchen and bedrooms.
The Pocket B unit plans (Units 1 to 4) on the M3M Forestia East floor plans page make a good practice set. Here is what they show:
| Unit | Room dimensions |
|---|---|
| Pocket B, Unit 1 | 2,440 sq ft. |
| Pocket B, Unit 2 | 2,440 sq ft. |
| Pocket B, Unit 3 | 2,455 sq ft. |
| Pocket B, Unit 4 | 2,455 sq ft. |
3 BHK or 3.5 BHK: Which Size Fits Which Household?
Choose the 3 BHK if you need three bedrooms and a comfortable living area. Choose the 3.5 BHK if you also want a flexible extra room, such as a study or utility space. Confirm the exact use and size of that half-room in the unit plan before deciding.
- Joint family: look for the number and size of bedrooms first, and check that the extra room in a 3.5 BHK is usable.
- Work-from-home couple: the extra room in a 3.5 BHK can serve as a dedicated workspace if it has a window and enough floor area.
- Investor targeting tenants: prefer the layout with the most efficient carpet-to-super ratio and fewer awkward corners.
- Long-hold end-user: prioritise room dimensions and storage over the headline size, since you will live with the layout for years.
Five Checks Before You Rely on Any Floor Plan
Before trusting any floor plan, make sure it is tower-wise, matches the plan sanctioned for the project’s registration, shows carpet and super area on one document, and that you have read what the agreement says about area variation. Then test your furniture against the real dimensions.
- Ask for the tower-wise plan in writing, not a generic layout.
- Confirm the plan matches the one sanctioned for the registration. The project is registered with HARERA Gurugram as
- M3M Forestia East I (registration no. 07 of 2026, dated 21 January 2026), and the certificate is the primary source.
- Make sure carpet area and super area appear on the same document.
- Read what the agreement says about area variation and what happens if the final area differs.
- Do a furniture-fit test: measure your bed, sofa and wardrobe and place them on the plan using real dimensions.
Why Size Matters in This Part of Manesar
