Quick Overview

4Square Park Sierra is an apartment project by 4SQUARE ESTATES at Shivanahalli village in Yelahanka, North Bengaluru. Karnataka RERA registered it on 17 March 2026 with 170 flats in one block of six floors above one basement.

The registered site is 1.26 lakh sq ft (2.90 acres), about 59 flats per acre.

About

4SQUARE ESTATES is a partnership firm with a Bengaluru address (PIN 560102) in the RERA record. In our Karnataka RERA data, checked 28 August 2026, Park Sierra is the only project registered under that promoter name.

A separate registration, 4 SQUARE WHITE PETALS (PRM/KA/RERA/1251/310/PR/190123/005628, approved 19 January 2023, due 30 September 2025), sits under the name 4 SQUARE REALTY. We have not established whether the two companies are related.

The same data shows no RERA complaints on Park Sierra and no extension filed for it; the project is new, so that record is short. The builder's website says it has 30+ years of experience and 25+ projects delivered.

We have not verified those figures, and our RERA data shows no finished project under this promoter name.

BBMP sanctioned the plan under BBMP/Addl.Dir/JDNORTH/0037/25-26, and the registration is PRM/KA/RERA/1251/472/PR/170326/008529. The RERA bank details name State Bank of India for the project accounts.

Portals disagree on who the builder is. Address of Choice names 4S Developers and Propsoch names Keerthi Estates, while Square Yards lists the project on a 4Square Estates page.

RERA registers it to 4SQUARE ESTATES, and the builder's own website is branded 4Square Estates.

The project has 170 flats on 2.90 acres. It suits someone who wants an apartment near Yelahanka town and can wait until late 2029. One nearby project, listed under Location, is due earlier.
