Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for reconfigurable spaces. One of the methods includes identifying plan information relating to a space under evaluation. Constraints related to structures associated with the plan information are identified. Input regarding uses or elements to be included in a reconfigurable design for the space is received. A library of elements for inclusion in the space is evaluated, including determining one or more reconfigurable elements that satisfy the received input. A first configuration of a reconfigurable element is determined including a first placement in a first design associated with the space, and the first design in accordance with the first configuration is presented. A second different configuration is determined, including a second placement in a second different design associated with the space, and the second different design in accordance with the second different configuration is presented.
