Parking filed74
Slots recorded per building wing in the filing. MahaRERA does not publish a two wheeler or four wheeler split, visitor parking, or the sanctioned allotment, so this is provision as filed and not a comparison against the approved plan.
Land and ownership1
MahaRERA does not publish landowner contact details. MahaRERA has published no encumbrance declaration for this project. That is silence on the question, and not a record of clear land.
| Landowner | Village | District |
|---|---|---|
| Charkop Anand CHS Ltd | Borivali | Mumbai Suburban |

The permission chain
The permissions a project needs, in the order they happen, matched to MahaRERA's own document slots. A slot on the file means the promoter uploaded a document there; it is not proof the permission was granted, and the filing carries no issue dates. An empty slot is not proof an approval is missing.
- Legal title reportOn the file
A lawyer's report on who owns the land and what is registered against it.
uploaded 2 Apr 2022 - Layout approvalOn the file
The planning authority's approval of how the plots and buildings sit on the land.

Frequently asked questions
What are my rights if DEM Cygnus is delayed beyond 31 Mar 2025?
Under section 18 of the RERA Act you may stay in the project and claim interest for every month of delay, or exit and claim a full refund with interest. In Maharashtra the rate is SBI's highest MCLR plus 2 percent, currently 10.90% per annum (June 2026). The free delay interest calculator on ReraGenie puts a rupee figure on any delay. Claims are filed as MahaRERA complaints with a Rs 5,000 fee.
How do I verify and contact the developer of DEM Cygnus?
The registered promoter entity is DEM ESTATES LLP, a partnership as per the filing. Neither this filing nor this promoter's other MahaRERA registrations disclose a CIN, LLPIN or GSTIN for this entity. Your agreement for sale must name this exact entity, not a group brand name. The promoter's registered address and contact details are on the project's MahaRERA listing (scan the QR code on any advertisement) and in its filed documents. The Rs 499 buyer report includes all of them as a single ZIP, foldered by type.
Is my payment protected in DEM Cygnus?
Partly, by law. 70 percent of every buyer payment must go into the project's designated bank account, withdrawable only against architect, engineer and CA certificates as construction progresses; since July 2024 MahaRERA requires a three-account structure for collections. Separately, a promoter cannot take more than 10 percent of the price before signing a registered agreement for sale (section 13). Neither rule guarantees completion; they limit how far your money can travel from the project.
How current is the construction progress shown for DEM Cygnus?
Promoters must file a quarterly progress report within 20 days of each quarter end, certified by the architect (Form 1), engineer (Form 2) and chartered accountant (Form 3). The figures above come from the latest filing, so they can trail the site by up to a quarter. A promoter who stops filing QPRs altogether invites penalties under section 61, and a stale filing date is itself a warning sign worth checking on the portal.
Who certifies construction progress at DEM Cygnus?
The professionals named in the filing: Architect: Hrishikesh Chandgude; Engineer: Gireesh Rajadhyaksha; Chartered Accountant: Virag Shah. Their Form 1 (architect), Form 2 (engineer) and Form 3 (chartered accountant) certificates are what unlock the promoter's withdrawals from the 70 percent account, so their names on record are part of the project's accountability chain.
What should I check before booking in DEM Cygnus?
Four things this page cannot decide for you: that the carpet area in your agreement matches the filed carpet area (the model agreement allows only a 3 percent variation, with a refund right below that); that the agreement follows MahaRERA's model clauses with deviations highlighted; the promoter's record on their other projects, not just this one; whether construction progress keeps pace with sales in the coming quarters. The Rs 499 buyer report works through all of them from the filings.
