Reason as filed by the promoterFollowing are the reasons for delay in construction works of the captioned Project: a. Immediately as we commenced the works of shore piling and excavation in November, 2021, the residents of the adjoining buildings with ulterior motives and desires, started to complain on frivolous and completely untrue grounds, including alleged noise/ sound that was generated in the process of such works. Although we had procured appropriate approvals, adhered to the law prescribed parameters of noise and also conducted further tests from accredited labs and implemented strong sound dampening measures to co
Reason as filed by the promoterFollowing are the reasons for delay in construction works of Astrum (“Project”): a. Immediately as we commenced the works of shore piling and excavation,we realized that the rock under the ground was much harder than shown in the tests,which left us with no choice but to explore more options like controlled blasting, diamond cutting, etc. which were much higher in cost and time consuming than the regular methods b. Although we had appropriate approvals for the above,the residents of the adjoining buildings with ulterior motives and desires,started to complaint on frivolous and completely untru
Reason as filed by the promoterFollowing are the reasons for delay in construction works of Astrum (“Project”): a. Extreme Climatic Conditions & Labour Shortages (March-May 2026): During the severe summer months of 2026, acute heat conditions impacted labour productivity due to dehydration and health risks, while reverse migration led to shortages of skilled and unskilled labour. Consequently, approximately two additional months of effective working time were lost despite efforts to maintain a fully mobilized site b. Ongoing Elections in states and the SIR process conducted there: During the months of March & April 2026 the

Frequently asked questions
What are my rights if Astrum is delayed beyond 31 Dec 2026?
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 Astrum?
The registered promoter entity is Upvan Developers, 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 Astrum?
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 do I read the complaint cases filed against Astrum?
Each case number above is a complaint MahaRERA hears in public. On the MahaRERA website, open Complaint Details and search the CC number: the order PDFs, hearing dates and disposal status are free to download. Orders bind the promoter. Before booking, check whether past orders were complied with, not just whether complaints exist; an ignored order is a stronger warning than the complaint itself.
How current is the construction progress shown for Astrum?
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 Astrum?
The professionals named in the filing: Architect: Uday Dhawan; Architect: Uday V Dhawan; Engineer: Zakirhusain Chaugule; Engineer: VP Consultants; Engineer: RECI Engineering; Chartered Accountant: M A Parikh Shah Associates. 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 Astrum?
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; how the declared litigation on this registration affects your risk; 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.
