What buyers actually paid: across 52 registered agreements, the effective carpet rate is ₹18,074/sqft, with eight in ten falling between ₹14,844 and ₹19,195 — computed from the agreement values and carpet areas the promoter filed, not broker quotes.
The inventory filing also declares: 22 owner/investor-held.
Read from MahaRERA on 19 July 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 52 homes carry one, and 190 of the 264 are recorded unsold.
Here is one of those unsold homes, priced against what buyers of the same home on other floors actually filed:
| Home | Carpet | Filed for the same home on other floors | Based on |
|---|---|---|---|
| 3702 | 643 sqft | Rs 1.1482 cr typical, over Rs 84.30 lakh to Rs 1.3473 cr | 33 filed at this size |
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 WINDSOR TOWER A, 125 of the 190 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.
The buildings and wings registered under this project, with each tower's sanctioned height and declared completion date. Here the tallest tower rises to G+41 and 264 homes are registered across the project.

🔒 What I’d do as a buyer here · Drawings Report
The report opens with what this project really is — read from its approved drawings — then the specific calls: the cheapest good way to buy here, the home to say no to, what you can stop worrying about, and what to get in writing before you sign anything.
🔒 Which home to ask for · Drawings Report
The home-level read: which ones to prefer and which to avoid, what the drawings put around each, and the things on this site nobody at the sales desk will tell you about.
The approved drawings
Everything above is on this page already, free, from the government record. The drawings are different: the 12 approved sheets are the same drawings the builder filed to get WINDSOR TOWER A 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.
