Counts and agreement value as the promoter filed them at the last compliance date; this is the filed inventory, not current availability. Of that agreement value, ₹4.88 Cr (about 9%) is recorded as collected and ₹49.47 Cr as receivable. The registration lists 264 units; this inventory lists 242. These are separate filed records. Their counts do not match; neither count establishes today's availability.

Filed agreement values: across 52 sold or booked entries with usable filed values and areas, 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.

What the filings record, unit by unit

Read from MahaRERA on 17 October 2026

This unit list contains 264 entries; the separate sales summary contains 242. The lists can differ in status coverage and filing date. Use the source date shown with each.

MahaRERA publishes, unit by unit, what this promoter filed: which units are sold and which are not, the RERA carpet area of each, and for sold or booked entries the filed agreement value — the consideration filed for that specific unit. On this project 81 units carry one, and 161 of the 264 are recorded unsold. Since we started watching this ledger, 44 units have moved out of the unsold list, most recently on 17 October 2026.

Here is one unit filed as unsold, beside the amounts filed for comparable units:

UnitCarpetFiled comparisonBased on
3702643 sqftRs 1.16 cr typical, over Rs 81.66 lakh to Rs 1.41 cr49 filed · similar area (within 2%), elsewhere in project

A filed consideration is the amount the promoter reported 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.

In WINDSOR TOWER A, 96 of the 161 unsold units have filed sales to compare with. The Sales Report gives each of them its own row — the filed agreements behind its comparison listed in full, the government reckoner value the promoter filed against it, and mortgage status where the filing supplies it. Missing mortgage information is not confirmation that a unit is free of a mortgage. Built from the filing itself, sent by email.
