Cadaster is a design practice focused on the infrastructures of architecture and territory. We are currently focused on the following inquiries: intervening in urbanization, rescripting of real property, preservation justice, contemporary environmentalities, and infrastructures of cooperation. These inquiries together frame our commitment to defining roles for architectural knowledge and practice in struggles for spatial justice.

Cadaster is based in Minneapolis.
