KEYSTONE DEVELOPERS is sister company of SANDSTONE INFRA INDIA PVT.LTD.
Why SandStone Infra India Pvt.Ltd started sister companies?
Sandstone Could not completed any project within time, they have bad feedback in the Hyderabad market. There are lot of buyers lost their money.
company websites:
https://keystoneventures.in/, https://sandstoneinfraindia.com/
Currently Keystone developers dealing two ongoing projects.
SBR Meadow, Patancheru, Hyderabad.
Urban Nest, Sulthanpur, Hyderabad.
Keystone Developers are not authorized to sale any open land, They are just mediators, Here Sandstone Infra deals projects with land lards, because landowners doesn’’t sign on buyers agreements.
My humble request, whoever already taken agreements from keystone developers please take landlord signs on your agreements, New buyers don’’t buy any property without landlord sign on agreements. 100% don’’t take any property without GHMC, HMDA LP approvals in Hyderabad.
