Community Development 03 is a 27-unit net-zero development created through a partnership between Habitat for Humanity of the Roaring Fork Valley, 2757 design co., the Roaring Fork Valley School District, Pitkin County, Aspen CORE, Holy Cross Electric Association, and NREL. Designed and built over six years, the project repeatedly adapted to external challenges, including local wildfires, the COVID-19 pandemic, and steep cost escalation. During the approvals phase, Habitat RFV and 2757 design co. also developed the Grand Avenue Duplexes in Silt, Colorado, which served as a proving ground and pilot project for the Basalt Vista community.
