Brother I think in Army housing scheme KDA-1 600 yards Plot price is around Rs.22.5 Million and 800 yards Plot price is around Rs. 32.5 Million. I am not sure about house prices but I think it should be around Rs. 36 Million for 600 yards house and Rs. 45 Million for 800 yards house.
There are few other prime gated housing schemes in karachi like Naval Housing scheme off Zamzama, 350 yards house will cost you around Rs. 34 Million & 800 yards plot will cost you around Rs. 60 - Rs. 70 Million. It is very secure and very nice housing scheme. There are few other good gated housing schemes like Airforce housing scheme near Baloch colony/Shaheede Millat flyover, Askari Cannt etc.
If your relative want house in the best gated housing scheme of karachi than I would advice you to buy a house in Army Housing Scheme -2 off zamzama DHA Phase 5. There are around 50 houses in this prime housing scheme and minimum price of 800 yards old house is around Rs. 90 Million. I live in this housing scheme and it is truly the best place to live in karachi. President Musharraf's family, top General's, bureaucrat's & businessmen's lives in this fabulous housing scheme.
