The Rosecrans was designed as a proposal to upzone single family lots for urban infill. To allow for mass customization and future adaptability, it is designed as a series of modules that are combined into a personalized configuration of housing units. This initial example has six units, ranging from a studio to a three-bedroom, as well as four single-car garages at the back of the building, accessed by a laneway. It is two stories and 4,800 square feet.

The entire roof is a communal outdoor space covered by a bifacial photovoltaic (PV) “solar trellis” that offers sun and rain protection while admitting light. The trellis is sloped to direct rainwater to the opening above the interior courtyard for harvesting and should generate enough energy to make this building a net energy exporter. The building is designed to the world’s highest standards for health, comfort, quiet, and efficiency.
