(Under Construction) Our most recent ADU (accessory dwelling unit) that’s currently being built in the South Broadway neighborhood. This project is located in a landmark district which comes with challenges from a design perspective and it’s also located on extremely sandy soil (some of the worst soil we’ve seen in Denver) and requires 21 helical piers under the foundation drilled 20 feet deep.

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.
