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 modern garage-to-ADU conversion was built to support aging in place while allowing for future expansion. Prenvalley Builders managed the full construction scope, transforming an existing garage into a durable, efficient living space despite tight site constraints. The result is a thoughtfully executed ADU designed for longevity, flexibility, and long-term value.
