Street Monkey Architects 

The homes are almost completely powered by rooftop solar panels, and on-site batteries store unused energy that can be sold back to the grid. Additionally, the buildings’ energy consumption is measured on an ongoing basis to adjust for power needs.

Each two-story, 1,600-square-foot structure is composed of six factory-built modules that arrived on-site with finished interiors. Once erected, the facades were connected together to smooth over transitional moments between the homes. Four houses face east-west, while six have a north-south orientation—and all of the roofs are topped with solar panels angled toward the path of the sun.
