(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 beautiful Sunnyside ADU was completed in the summer of 2024. It features a 2.5 car garage, 2 bedrooms, 1 bathroom, a kitchen/ living area and vaulted ceilings/ dormers that provide a lot of character in and out of the structure.

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.
