This two-story, design-build ADU in Denver’s City Park neighborhood is Prenvalley Builders’ largest accessory dwelling unit to date, totaling approximately 2,000 square feet. Designed for long-term flexibility, the home includes three bedrooms, a private office, an open living and kitchen area, in-unit laundry, and an integrated 2.5-car garage. Thoughtful layouts, high-performance systems, and durable finishes create a comfortable, efficient living space that supports both daily use and long-term rental potential.

This custom two-story ADU in Denver was designed and built in partnership with the Denver Housing Authority as part of the West Denver Renaissance Collaborative. Built above a garage with exterior stair access, the project delivers durable, high-performance housing while demonstrating how thoughtful ADU design can support neighborhood density, long-term livability, and citywide housing goals.

This compact Denver ADU was constructed by Prenvalley Builders as an efficient, small-footprint backyard residence. Built on a helical pier foundation to reduce site impact and control costs, the project required thoughtful sequencing, precision framing, and careful coordination to maximize usable space. The result is a durable, well-built accessory dwelling unit designed to perform efficiently within a tight urban lot.
