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.

No litigation declared on this project's K-RERA filing.

All 16 standard compliance document slots have usable uploaded filings.

No completion certificate (OC) on file yet — project has not been declared complete.

⚠ Registration validity has lapsed: originally due 20 Nov 2017 — which has passed with no OC on file.

Named utility/regulatory approvals

Electricity (BESCOM/ESCOM)✓ On file (All NOCs from Authority)
Water & sewage (BWSSB/KWSSB)✓ On file (All NOCs from Authority)
Fire NOC✓ On file (All NOCs from Authority)
Pollution control (KSPCB)✓ On file (All NOCs from Authority)

"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.

Project team & certifications

RERA filing

K-RERA names 3 project professional/vendor rows across Architect, Contractor, Structural engineer. Use this to cross-check whose certificates, drawings, and contractor commitments support the filing; final reliance still belongs with your lawyer/technical reviewer.

Builder track record

RERA filing

Carbon Developers has 2 other K-RERA-registered projects in our records. 2 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.

Financials & Construction Progress

Financial disclosures

RERA filing

⚠ 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 ₹25.3 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: Axis Bank : Kalyan Nagar (IFSC UTIB0000734, a/c …3572). 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.

Construction photo filings

RERA filing

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.
