3.2. Urban Fabric
To define the composition of the urban fabric it’s been considered near term building technologies and the requirements on both connection (to provide loop egress) and separation between buildings (to avoid collapse of neighbor structures in case of an accident). It is decided to fill the inner parts of the array with a set of independent buildings of small-medium size, connected together both in the underground floor and (when needed) one floor above the surface.

PROS
· Independent buildings from the circular axes provide more freedom both in shape and size.
· Large ranges of technologies available as buildings are independent one of the other.
· Separation between building up to 5 meters to allow reparation and regeneration.
CONS
· Eclectic look.
· Connections between buildings are extensive.

Some requirements will anyway drive the position of the buildings in the ring’s interior:
· Illumination of the buildings, especially transparent greenhouses (shade-light).
· Proximity between Private buildings and Common areas.
· Industrial areas separated from Accommodation areas.
· Manufacturing areas connected with wheeled transportation routes.
· Private accommodation buildings close to each other to provide multiple egress exits through the underground level and upper level connections.

All the buildings will have underground floors with connection to other buildings. These underground areas will have round shapes many times due to the internal pressure and will be dedicated to storage, installations machinery and other uses.

The habitable areas of the buildings will be situated on the above ground levels but some of them, such as the Common Areas can have multiple storey connected through empty spaces (such the structure of a mall) and in this case the underground level would also be used as such using a courtyard to illuminate it and as a connection to the ring and the neighbor buildings.
