Legal, Approvals & Project Team

Litigation & compliance

RERA filing

Litigation status was not supplied in the captured record. This is not confirmation that there are no cases.

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.

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 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: 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.
