About this file

This is a conceptual site plan document for Willoughby Corner Phase 2A & 2B, a multi-family residential development project in Lafayette, Colorado, prepared for the Boulder County Housing Authority (BCHA). The project encompasses 96 dwelling units across two phases on approximately 4.25 acres. Phase 2A includes 32 apartments (2-story, neuroinclusive design) with 16 one-bedroom/one-bathroom units and 16 two-bedroom/two-bathroom units, totaling 25,248 square feet of net rentable space within a 36,886 gross square foot building. Phase 2B consists of 48 apartments comprising a 12-unit 2-story building and a 36-unit 3-story garden-style building, with varied unit configurations including one-bedroom, two-bedroom, and three-bedroom units. The development is designed with a 1.5 to 1.6 parking space per dwelling unit ratio and includes on-site amenity and maintenance areas. The plans include detailed first and second floor composite layouts showing unit distributions, circulation patterns, stairs, elevators, and common areas.

The Willoughby Corner project is part of a larger 400-unit affordable housing development spanning 24 acres near 120th and East Emma Streets in Lafayette. BCHA is seeking qualified Construction Manager/General Contractor (CM/GC) proposals to provide pre-construction, construction, and construction administration services for Phases IIA and IIB. The project will be financed primarily through low-income housing tax credits (LIHTC) administered by the Colorado Housing Finance Authority (CHFA) and Private Activity Bonds, with the goal of delivering permanently affordable homes in multiple housing types to address regional housing affordability needs. Interested firms should submit proposals collaboratively and contact procurement@bouldercounty.gov for additional procurement process information.
