The first step to making plans for a $20K House available to builders is finding a design that work. Like the three $20K House projects built before theirs, the student team behind the Pattern Book House worked together to present a prototype of what such a home could look like. "There had been some community backlash to some of the previous prototypes," Grubb says. "We wanted to design something that the community would accept." To that end, they used a rain screen on the exterior walls to mimic siding on the area's traditional homes and chose cedar, as opposed to corrugated metal like other teams had done, so the locals could “compare it to a honey shed," Grubb adds.
