This Denver ADU project was designed and built within a landmark context and presented unique site challenges, including extremely sandy soil conditions. Through a coordinated design-build approach, Prenvalley Builders engineered a durable foundation solution and carefully executed construction on a tight urban lot. The result is a thoughtfully integrated accessory dwelling unit built for long-term performance and compatibility with its surroundings.

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 design-build ADU showcases how thoughtful planning can deliver a large, flexible living space within Denver’s urban zoning constraints. With a two-story layout, integrated garage, and adaptable work areas, the project balances square footage, performance, and cost-conscious decision-making. It stands as one of Prenvalley Builders’ largest ADUs to date, designed to support long-term use and evolving needs.
