Frequently asked questions
What are my rights if ISLE OF TREES is delayed beyond 29 May 2028?
Under section 18 of the RERA Act you may stay in the project and claim interest for every month of delay, at the rate the state's RERA rules prescribe, or exit and claim a full refund with interest. Claims are filed as complaints with RERA Karnataka.
How do I verify and contact the developer of ISLE OF TREES?
The registered promoter entity is Happiness Harmony Property Developers Private Limited, a company as per the filing. Its CIN U70200TN2018PTC121367 and GSTIN 29AAECH4663H1ZC 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 RERA Karnataka listing and in its filed documents.
Is my payment protected in ISLE OF TREES?
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. 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 ISLE OF TREES?
Each case number above is a complaint filed with RERA Karnataka. 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.
Who certifies construction progress at ISLE OF TREES?
The professionals named in the filing: Architect: Mr. Vivek V. Shankar; Engineer: Vishnu Kumar; Chartered Accountant: Gopalan Muralidharan. Their 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 ISLE OF TREES?
Four things this page cannot decide for you: that the carpet area in your agreement matches the filed carpet area; that the agreement follows the model agreement under the state's RERA rules, 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.
