A careful investigation of the residential neighbourhoods of Oerlikon shows a substantial presence of small construction businesses in appropriated garages, underground parkings or small annexes of existing apartment houses. Even though these spaces are not designed for production and far from ideal, they still provide central as well as affordable working and storage space. However, as the Richtplan plans to densify the area by 150 to 270 percent, these businesses now risk being displaced out of town. This master thesis proposes a model in which small production companies can co-exist with housing. Learning from the spatial intelligence of the observed businesses intertwined with living in Oerlikon, the master thesis proposes a continuation of the productive history of MFO with a mixed-use development of different work-life typologies centred around a workyard. This enforces an ecological ‘city of short distances’ allowing for sustainable interaction between housing, production and maintenance facilities.
