Yes, Godrej group is very good. But if you have plans then book it as soon as possible because when i enquired about this project all the flats were almost booked.
Reliable builders in Kolkata are the ones that have been in the market for over a period of time. The booming real estate market has made sure that small time developers are also jumping in to carve a niche for themselves. DLF, Unitech and Godgej Group have a pan India presence and are largely good to deal with mostly positive review. Out of the local Kolkata centric builders Hiland Group, Ruchi Group, Fortune realty and Pearls Realty developers have a good market presence and good quality of service. BGHDC, Canopy, Bengal Shristi Infrastructure, Bengal Greenfield and Mani Group are also good names in the Kolkata real estate market.
Kolkata is a huge real estate market with a large number of big and small real estate developers and colonizers in the market today. It would be better if you can make break it into individual discussion threads for popular builders and small time ones. To answer your question some of the well known developers and builders active in Kolkata include Aspiration & INKA Group, Siddha Group, Godrej Properties, Belani Group, Hiland Group, Fortune Realty, Unitech and Ruchi Realty Holdings Ltd. Active acres by uchi group and Unitech Vistas by Unitech are two of the most popular realty destinations in the city today although a large number of developers are now focusing in suburbs including EM Bypass area.
