Cadaster is a design practice focused on the infrastructures of architecture and territory. Our work responds to the pervasive structures that govern environments. Through design, teaching, research, and advocacy, we are currently pursuing several design trajectories, including intervening in urbanization, the rescripting of real property, preservation justice, contemporary environmentalities, and infrastructures of cooperation. Together, these frame our commitment to  defining and advancing architecture’s role in struggles for spatial justice.

Intervening in Urbanization
Suspending urbanization through anticipatory and spatially pervasive design processes.

Rescripting Real Property
Deploying property geometries and socio-legal arrangements for counter-hegemonic land claims.

Preservation Justice

Supporting collective aspirations through historic material culture.

Contemporary Environmentalities
Engaging with territories of ecological conflict irreducible to human agency.

Infrastructures of Cooperation
Mediating collectivity and political transformation through spatial configurations.

Cadaster is based in Minneapolis.
