I think it is good, purpose built for living and rates of villas are quite reasonable You can always go and see of their sample villas or others which are nearing completion.
The size of villas ranges from sizes from 1500 sq. ft to 2604 sq. ft with very affordable price. The price of the villas ranges from Rs 45lakhs to Rs 59lakhs.
As far as a builder- Eldeco has got quite good success with its previous ventures into flats. If you look at some of their completed projects which has been a few years old already- they appear to be maintained well and are in good condition.
Eldeco City is one of the upcoming project of Eldeco Infrastructure and Properities Ltd. Eldeco City offers 1bedroom, 2bedroom, 3bedroom, 4 bedroom and 5 bedroom Simplex & Duplex Expandable Villas with modern amenities.
