Using local relations like angles, distances, sizes and programme, varying cellular units aggregate around primary circulation cores, defining habitable interiors. These individual cells interconnect by merging skins or using connection slabs and bridges, creating structurally independent entities suspended within the main fibre structure. The geometrical definition of these spatial units is informed by the location of floor slabs, their connection to local fibrous structures and the enclosing skin. Floor heights are defined by circulatory and programmatic requirements, varying from a layered infill of office floors to an open auditorium. The geometry, density and size of the local fibrous structure depend on the size of the spans between and the amount of connection points to load bearing floors. The skin, interacting with the geometries of the secondary structure, produces a performative system of shapes and openings informed by local conditions such as programme, interaction with neighbouring cells, overall position within the network and environmental conditions such as light and wind. This results in facades with varying curvature, opacity, perforation and material.
