🔒 What I’d do as a buyer here · Drawings Report
The report opens with what this project really is — read from its approved drawings — then the specific calls: the cheapest good way to buy here, the flat to say no to, what you can stop worrying about, and what to get in writing before you sign anything.
Registration-form facts from the K-RERA detail page: use these to sanity-check the builder brochure, parking allotment, and sanctioned-plan references before relying on plan-extracted approximations.

| Registered land area | 18,312 sqm | The land area attached to this K-RERA registration. |
| Sanctioned FAR/FSI | 2.25 | Higher FAR generally means a denser vertical build, subject to site layout and open-space design. |

| Parking disclosed | 304 total (304 covered, 0 open) — 1.27 spaces/unit | Confirm whether your quoted unit includes an allotted parking space and where it sits. |

What the numbers tell you
Synthesis from the official RERA scale, unit register, and land rows — the read a sales team won't volunteer.
🔒 Which flat to ask for · Drawings Report
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.
8 of 31 compliance document slots are filed as Not Applicable; the remaining 23 slots have usable uploaded filings.
No completion certificate (OC) on file yet — project has not been declared complete.
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.
Clean approvals profile: every applicable statutory NOC is on file — including Fire NOC, environmental clearance and pollution-control clearance (KSPCB), the clearances buyers most often find still pending. Nothing is outstanding among the statutory NOCs — which compliance documents are filed versus still under process is a separate matter, covered in Litigation & compliance above. Since these are developer-filed portal statuses, have your lawyer confirm them against the linked NOC copies.
3 further authority slots are marked not applicable by the regulator.

K-RERA names 4 project professional/vendor rows across Chartered accountant, Engineer, Architect, Contractor. Use this to cross-check whose certificates, drawings, and contractor commitments support the filing; final reliance still belongs with your lawyer/technical reviewer.

Rainvas Infraa 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.
Latest quarterly filing (2026-Q1): ₹2.23 Cr collected from buyers, ₹2.23 Cr withdrawn from the project's escrow account.
| Construction progress | 10% → 11% (+1 pts) |
| Units sold/booked as registered | 8/240 (3%) |
| Buyer collections in available QPRs | ₹2.23 Cr |
| Escrow withdrawals in available QPRs | ₹2.23 Cr (1.00x collections) |
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 ₹59.1 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: HDFC KASTURBA ROAD IFSC Code : HDFC0000009 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.

The approved drawings
Everything above is on this page already, free, from the government record. The drawings are different: the 2 approved sheets are the same drawings the builder filed to get RAINBOW UNO 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.
Want this project read from its filed drawings?
232 of the 240 flats are not yet sold in the latest quarterly filing, so which one you take is a real choice. With 11% reported construction progress, there is no finished building to walk through — the approved drawings are the only place to see what you are buying. We read the 2 approved drawings on RAINBOW UNO’s file and tell you which flats we would ask for, what sits around them, and what to get in writing before you pay the token.
This page is the free K-RERA filing summary. For RAINBOW UNO, one reading of it goes further. Which flat should I ask for? — what the approved drawings and filed papers say about the flats, the parking, the approvals, and what to get in writing before you sign. That is the Drawings Report.
