About

Corbital Builders is a partnership firm and the promoter on the RERA record. Our Karnataka RERA data, updated on 28 August 2026, holds one project under that name, which is Cosmos. It shows no deadline extension and no complaint against the project.

With one project in our data, there is no earlier delivery record to read.

The RERA filing uses the same name as ours, in capitals. The registered address is at Kyalasanahalli village in K R Puram Hobli, PIN 560077.

Quietlist files the project under Chikkakannalli, and the approved pin in our own record points to Poojenahalli near Devanahalli. Both disagree with the registered address, so the Location section measures from Kyalasanahalli.

The project has 68 flats in one block of three floors.

The filing gives the project start as 1 July 2026 and the possession date as 31 December 2029, about 3 years and 5 months after registration.

The construction schedule in the same filing puts the framed structure at 29 April to 21 May 2026 and the masonry at 29 April to 28 May 2026, before the 16 July 2026 registration date.

Fire-fighting fittings are scheduled for 1 July to 31 December 2027, weatherproofing for 5 April 2027 to 30 August 2028, and landscaping and external work for 1 January to 31 December 2029.
