This anthology presents work on cultures of assembly. It stresses the relevance of small-scale and decentralized spatial formats of local knowledge production to community building and embedded political decision-making in the context of the socio-ecological transition. It reinforces the role of both individual and collective action while proposing distributed assembly and proximity as core attributes in the production of the contemporary and future city. It calls for a revised form of spatial politics. Miessen's ongoing research trajectory Cultures of Assembly was initially kicked off during a Harvard GSD fellowship in collaboration with Joseph Grima, in which the two architects investigated the sociopolitical dimension of (urban) spatial design.
