"The Cube houses constructed in Rotterdam and Helmond in Netherlands feature a bunch of cubes placed on the base building as if to form a roof. The Cube houses have been designed by Piet Blom. Each cube house represents a tree and together the houses form a grove?seems like a village within the city. These houses were built in 1997. Looking at the houses, we can say that even diagonal structures can be inhabited. There are three floors in this house. Enter the house from the entrance on the ground floor. Climb up the first floor to reach the living room and open kitchen. The second floor has two bedrooms and bathroom. Some of these houses have a small garden on the top floor.
