The average covers the registered land and all registered unit types. It does not describe the space, outlook or surroundings of an individual home.

From another project · Prestige Park Grove

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 illustrates the report format. These findings concern the named sample, not this project.

This project, on the record

The comparable facts of this project, from its own RERA registration record. Each context percentile names its exact comparison set, drawn from Quietlist’s full register store. The paid report adds drawing-read rows to this same table — what the filed plans show about the site, its edges and the unit layouts.

Builder track record

RERA filing

Birla Arnaa has 3 other K-RERA-registered projects in our records (average reported construction progress 28%). 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 filing

Latest quarterly filing (2026-Q1): ₹2.86 Cr collected from buyers, ₹0.58 Cr withdrawn from the project's escrow account.

Construction progress3% → 4% (+1 pts)
Units sold/booked as registered439/463 (95%)
Buyer collections in available QPRs₹19.13 Cr
Escrow withdrawals in available QPRs₹18.93 Cr (0.99x collections)
  • Construction progress moved from 3% to 4% across the filed QPR window.

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 ₹66.2 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: ICICI Bank K H Road, Bangalore IFSC Code : ICIC0001937 Pin Code : 560027. 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.
