Each building has 27 floors and accommodates approximately 10?000 low-income residents. Each block is topped with outdoor swimming pool and a lot of greenery.

The facilities included do not end. The complex also features indoor swimming pools, fitness rooms, solariums, saunas, tennis courts, schools, 2 medical centres, church, shopping mall, restaurants, 3?400 underground parking spaces and a metro station.
