What buyers actually paid: across 788 registered agreements, the effective carpet rate is ₹22,613/sqft, with eight in ten falling between ₹21,004 and ₹26,028 — computed from the agreement values and carpet areas the promoter filed, not broker quotes.

No units are declared mortgaged, reserved, investor-held or not-for-sale in this inventory filing.

What the filings record, home by home

Read from MahaRERA on 08 September 2026

MahaRERA publishes, home by home, what this promoter filed: which homes are sold and which are not, the RERA carpet area of each, and for the sold ones the registered agreement value — the consideration filed for that specific home. On this project 788 homes carry one, and 42 of the 830 are recorded unsold.

Here is one of those unsold homes, priced against what buyers of the same home on other floors actually filed:

HomeCarpetFiled for the same home on other floorsBased on
F- 0204572 sqftRs 1.2589 cr typical, over Rs 1.1848 cr to Rs 1.5317 cr164 filed on this stack, floors 3–47

A filed consideration is what was registered for one {unit}. It is not a valuation, and MahaRERA does not publish the date of any of these agreements — read a range as a spread, not as a trend. An unsold row means no sale had been filed for it when we looked, which is a filing state, not a promise that the {unit} is available to you today. Only one observation of this ledger so far: no change can be reported yet. This observation is an archived copy whose time is the moment the file was written, not a portal fetch time.

In Atmosphere O2, 34 of the 42 unsold homes have agreements filed on their own stack. The Sales Report gives each of them its own row — the filed agreements behind that stack listed in full, the government reckoner value the promoter filed against it, and whether it is mortgaged to a lender while still on the unsold list. Built from the filing itself, sent by email.

Legal & Litigation

The promoter has declared 5 court cases on this project to MahaRERA. 2 are still pending. Litigation can cloud the land title or stall the build — have a lawyer pull the cause list for each and confirm whether it touches the title to your home. This is declared by the promoter; there may be further cases not on the RERA record.

Site & infrastructure

What this project's sanctioned plan shows — read for you
Where the plan is legible, the full report reads this project's layout plan filed with MahaRERA and lays out what's on it: where the utilities and open space sit, how the site is laid out around them, and which way it faces. When a plan can't be read clearly, we tell you plainly rather than guess.

The approved drawings

7approved drawings on file
10other papers filed

Everything above is on this page already, free, from the government record. The drawings are different: the 7 approved sheets are the same drawings the builder filed to get Atmosphere O2 approved — what sits under each tower, which floor holds machines, what the sales sheet leaves out. Nobody reads them for you. We do.

What that turns up — from other projects’ filings:

ATS Knightsbridge · Sector 124, Noida

You pay for 10,000 sq ft. The floor inside your home is 6,982 sq ft. The rest is walls, shared circulation and services. Get both numbers written into your agreement before you pay any booking amount.

Oberoi Elysian · Goregaon East, Mumbai

“The building is complete.” The tower has reached full height — true. The same filed certificate, same page: sanitary fittings 6% done. Ask for a possession date in writing.

Godrej Aristocrat · Sector 49, Gurugram

Paying extra for the top floor? The terrace drawing shows what sits on the slab above those flats: the overhead water tanks, the lift machine rooms and the roof machinery. Ask which flat sits under which.

Prestige Camden Gardens · Thanisandra, Bengaluru

The approved parking table asks for 12 visitor spaces. It shows 0. Two-wheeler spaces: also 0. Ask in writing where visitors will park.

What to verify before you book

  1. Confirm the MahaRERA registration is live and read the project page on the MahaRERA portal for the sanctioned plan, approvals and the promoter's quarterly progress reports.
  2. Check the declared completion date against actual site progress — registration is not the same as a delivered, occupancy-certified building.
  3. Verify the exact carpet area, floor and unit number in your agreement match the sanctioned plan (not the brochure's saleable area).
  4. Confirm the title, the 7/12 land extract and that your payments go to the project's designated RERA escrow account.

Flags are from MahaRERA's own published problem lists — not a claim about the developer's intent. Explore every flagged project on our Mumbai, Thane & the MMR RERA red-flag register.
