🔒 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.
| Disclosure | Official value | Why it matters |
|---|---|---|
| Registered units | 84 | Total inventory registered with K-RERA. |
| Official carpet area | 5,649 sqm | Regulator-disclosed project-level carpet area, not vision-derived room sums. |
| Official built-up area | 6,269 sqm | Useful scale context when comparing density and project cost. |
| Registered land area | 4,046 sqm | The land area attached to this K-RERA registration. |
| Sanctioned FAR/FSI | ~1.75 | Sanctioned floor-area ratio (≈7,081 sqm sanctioned FAR area ÷ 4,046 sqm land) — higher means a denser vertical build. |
| Registered towers/wings | 1 | Official tower/wing count in the K-RERA detail page. |
| Parking disclosed | 93 total (84 covered, 7 open) — 1.11 spaces/unit | Confirm whether your quoted unit includes an allotted parking space and where it sits. |
| Approved plan number | PRJ/10120/21-22IN | Use this to match the sanctioned drawing set shown by the builder. |
| Plan approval date | 09-02-2022 | |
| Project start date | 24-02-2022 |
K-RERA registration tables showing the project mix and tower/wing scale. Use this to sanity-check sales claims such as "only large homes", "low density", or "plenty of parking" against the filed inventory.

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.
7 of 27 compliance document slots are filed as Not Applicable; the remaining 20 slots have usable uploaded filings.
No completion certificate (OC) on file yet — project has not been declared complete.
⚠ Registration validity has lapsed: originally due 31 Oct 2024 — which has passed with no OC on file.
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.
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.
| Role | Name | Registration / licence | Since | Locality |
|---|---|---|---|---|
| Chartered accountant | Hemdari Kolla | 224623 | 2010 | Bengaluru Urban, Karnataka - 560016 |
| Engineer | G Mohan Reddy | 322/A/Engg | 1991 | Hyderabad, Telangana - 500044 |
| Architect | T V Srinivas | CA/97/21898 | 1991 | Hyderabad, Telangana - 500044 |
| Contractor | Kurapati Durga Prasanth Reddy | - | 2015 | Bengaluru Urban, Karnataka - 560066 |
⚠ 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 ₹19.0 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.

The approved drawings
Everything above is on this page already, free, from the government record. The drawings are different: the 7 approved sheets are the same drawings the builder filed to get Oakstone Lakeview 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.
