What buyers actually paid: across 27 registered agreements, the effective carpet rate is ₹19,546/sqft, with eight in ten falling between ₹15,489 and ₹24,250 — computed from the agreement values and carpet areas the promoter filed, not broker quotes.
The inventory filing also declares: 10 reserved and 3 owner/investor-held.
Read from MahaRERA on 11 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 27 homes carry one, and Every home on the filing is recorded sold or booked.
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. One of the two observations is an archived copy whose time is the moment the file was written, not a portal fetch time.
Every home in ASTRUM ANNEX is filed sold or booked, so there is no asking price left to test — but the record of what this project sold for is complete. The Sales Report lists all 27 registered agreements: each home, its carpet area, the consideration filed against it and the rate that works out to. 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+9 and 61 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 3 approved sheets are the same drawings the builder filed to get ASTRUM ANNEX 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.
Buying in ASTRUM ANNEX?
All 27 homes show as sold in the latest filing, so a purchase here is resale — most of what the register knows is already on this page. Eight in ten of the 27 registered agreements here fall between ₹15,489 and ₹24,250 per sq ft of carpet area — a spread worth checking your quote against before you pay a token. The completion date has been revised 2 times on the register. Buying resale? We read the 3 approved drawings on ASTRUM ANNEX’s file and tell you which homes we would ask for, what sits around them, and what to get in writing before you pay the token.
