GROOF: Merging the ground and roof level

This design is to use flexible space generated by duplicable structures from Kiyonori Kikutake Metabolism to help create endless and boundary less landscape as described in No stop City by Adrea Branzi.

The current proposal of governor island by west 8 has many drastic mounts that sacrifice much of the ground space. Therefore, in order to make use of the public space, the design intends to remove the hierarchy through enlarging roof level area, trying to achieving “horizontality”. In the meantime, multiple landscape infrastructure typologies are used to blur the edges of the ground and roof，providing broader and richer public space.

The design starts by analyzing hill slopes and flooding zones in governors island and obtain areas with different potentials. The proposal uses different combinations of 3 types of arch structures as the primary structure to frame the horizontal space pattern which could adapts to the topography. Then it uses vertical bowls as the secondary structures which hang down from arches. The dome structure works as the tertiary structure to offer circulation and service space, both intersecting the arch and bowl structure.
