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.

Extensions applied for2
A revised date filed with the regulator does not change the possession date in your agreement for sale.
Reason as filed by the promoterWe have now obtained revised plans approved from SRA, wherein they have approved elevation of the height of the proposed building and change in the area of the flats. We have opted for going in high rise building construction (i.e. from earlier 70m to 120m) after receiving incentive FSI from the authority, hence, completion of project will take more time. Also, the workers were not working in full capacity because of the pandemic . Hence, we request you to grant us an extension.
Reason as filed by the promoterWe apologize for the delay in the completion of the project and the submission of this request. The delay has occurred due to unforeseen circumstances, including procurement issues, financial constraints, and site challenges. Despite these setbacks, we are working diligently to address these issues and complete the remaining work. Given the circumstances, we kindly request an extension until 31-12-2028. to complete the project and fulfil all regulatory requirements

Frequently asked questions
What are my rights if SKY ANNEX is delayed beyond 31 Dec 2028?
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 SKY ANNEX?
The registered promoter entity is Stans Buildtech Homes Private Limited, a company as per the filing. Its CIN U43299MH2023PTC416231 and GSTIN 27ABMCS4067K1ZQ can be cross-checked on the MCA and GST portals. 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 SKY ANNEX?
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 SKY ANNEX?
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 SKY ANNEX?
The professionals named in the filing: Architect: ELLORA PROJECT CONSULTANTS PRIVATE LIMITED; Architect: DESIGN SPHERE ARCHITECT INT. DESIGNER; Engineer: SK Consultants & Engineers; Engineer: Shaikh Mohammed; Chartered Accountant: N B Sayed & Associates; Chartered Accountant: A. S. SUTERWALA & CO. CHARTERED ACCOUNTANTS. 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 SKY ANNEX?
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; why the completion date was revised and what the new timeline depends on. The Rs 499 buyer report works through all of them from the filings.
