Project Review · example purchase
Spending a few crores on a home? ₹4,999 to check what you’re buying.
Check what the plans put beside your home, below it and in front of it. The view, nearby buildings and shared facilities can change what you are buying.

From another project · Prestige Park Grove · earlier comprehensive example
A larger advertised area. Almost the same carpet area.
In Tower 14, E4 has 141 sq ft more saleable area than E2. Its carpet area is only 0.46 sq m larger. The report puts the two layouts side by side.
This longer example shows the depth of research available in Project Deep Dive. These findings concern the named sample, not this project.

Builder track record
RERA filingBirla Arnaa has 3 other K-RERA-registered projects in our records (average reported construction progress 23%). 0 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 lower 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.
Financials & Construction Progress
Financial disclosures
RERA filingLatest quarterly filing (2026-Q1): ₹11.40 Cr collected from buyers, ₹9.04 Cr withdrawn from the project's escrow account.
| Construction progress | 16% → 19% (+3 pts) |
| Units sold/booked as registered | 470/473 (99%) |
| Buyer collections in available QPRs | ₹88.10 Cr |
| Escrow withdrawals in available QPRs | ₹27.49 Cr (0.31x collections) |
- 99% of registered units are shown as sold/booked, but no completion certificate is on file yet.
- Construction progress moved from 16% to 19% across the filed QPR window.
- The builder has drawn 0.31x of buyer collections from escrow (about 31% of the ₹88 Cr collected) — money is largely staying in the regulated escrow account rather than being pulled out ahead of spend, which is the safer direction. A ratio near or above 1.0 would be the one to scrutinise.
QPR figures are developer-filed quarterly disclosures. Collections and withdrawals are not a project valuation; they are a sanity check for whether sales, construction progress, and escrow draws appear directionally aligned.
Declared construction cost ÷ registered units averages to ₹63.3 lakhs per unit — the developer's own declared construction/development cost, not a unit agreement or asking price. This project-cost average cannot establish whether a quoted unit price is fair. Compare the exact unit, area basis, date and included charges in any price evidence.
RERA 70% project account is on file: ICICI Bank RD RICHMOND IFSC Code : ICIC0000269 Pin Code : 560001. 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.
