What the numbers tell you
Synthesis from the official RERA scale, unit register, and land rows — the read a sales team won't volunteer.

The flat-level read: which towers and floors to prefer and which to avoid, what the drawings put above, below and beside each flat, and the things on this site nobody at the sales desk will tell you about.
No litigation declared on this project's K-RERA filing.
3 of 35 compliance document slots are filed as Not Applicable; the remaining 32 slots have usable uploaded filings.
No completion certificate (OC) on file yet — project has not been declared complete.
⚠ Registration validity has lapsed: originally due 30 Jun 2020, extended (Section 6 Extension) to 30 Mar 2022 — both dates have passed with no OC on file. The extension on file was granted on 23 Feb 2023 (K-RERA extension no. EX/PRM/KA/RERA/1251/310/PR/230223/000550) — it has been used, its deadline has also passed, and no further extension is recorded.
Named utility/regulatory approvals
"Not found in catalog" can mean the approval genuinely isn't on file yet, or that it doesn't apply to this project (K-RERA doesn't tell us which). Ask the builder directly for any marked not found before relying on it.

Mantri has 8 other K-RERA-registered projects in our records — grouped across the several project-specific entities this developer registers under (e.g. this project is filed as “Mantri Developers”). 8 are past their declared completion deadline with no completion certificate recorded — but because K-RERA publishes OCs inconsistently, a project that has actually been finished and handed over still shows up this way, so this overstates real delays, especially for a high-volume established builder. That is a higher delayed rate than the K-RERA average across Bengaluru on the same measure.
Read this as a list to spot-check for a pattern of genuinely stalled projects, not as a delay rate — pull up a few of the builder’s other K-RERA registrations and check whether they’ve actually been delivered.
⚠ No quarterly financial disclosures (collections, escrow withdrawals) on record, despite no completion certificate yet — meaning we can't verify the project's cashflows against its construction progress. Worth asking the builder directly why no quarterly filings are available.
Declared construction cost ÷ registered units averages to ₹73.4 lakhs per unit — the developer's own declared construction/development cost, not a sale price. K-RERA filings don't disclose what the builder is charging, so this can't tell you whether you're getting a fair deal — only you comparing your quoted price against comparable listings nearby can answer that.
RERA 70% project account is on file: Bank of Baroda Altamount Branch, Mumbai (IFSC BARB0ALTAMO, a/c …1044). RERA requires 70% of buyer collections to sit in this separate, project-specific account, drawn only against certified construction milestones — confirm your payments are made to THIS account (not a general builder account) and that it appears on your allotment letter.
K-RERA has 1 project-photo upload.
These are developer-uploaded progress photos in the official document catalog. We do not treat them as proof of current site condition; use them as a prompt to ask for newer dated photos or a site visit. Individual filings are listed in the document catalog below.

The approved drawings
Everything above is on this page already, free, from the government record. The drawings are different: the 5 approved sheets are the same drawings the builder filed to get Mantri Webcity3C 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.
