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 Golden, Colorado renovation transformed a single-story home through a thoughtfully executed second-story addition and full main-level remodel. The project added a new upper level with a primary suite, additional bedrooms, and bathrooms, while reworking the lower floor to support improved circulation, structural integrity, and everyday livability. Designed and built to integrate seamlessly with the existing home and surrounding neighborhood, this project reflects Prenvalley Builders’ expertise in complex vertical additions and whole-home renovations.
