From the documents the promoter uploaded to Karnataka RERA, collected 22 Oct 2026. “Filed” means a document is on RERA — we have not checked its contents or validity. Not every approval applies to every project (for example, smaller projects may not need an environment clearance). The project page on RERA lists each upload.
