The design of each house is based on a single prototype floor plan with multiple façade variations, creating a mixed, yet unified, neighborhood. The homes are designed to meet ENERGY STAR Version 3 Performance Criteria, incorporating energy efficient appliances, lighting, HVAC, and a well-insulated thermal envelope. The project was developed by The Keystone Challenge Fund in conjunction with the Polk County Housing & Neighborhood Division. It is to receive funding through U.S Department of Housing and Development’s Neighborhood Stabilization Program (NSP3).
