Union Tower West

About the Project

Located in the Lower Downtown (Lo-Do) district of Denver, this mixed-use project helps activate the area around the historic Union Station and extends the concepts of connectivity, walkability, and urbanism inherent in the overall master plan for Denver’s newest neighborhood. This mixed-use project features a 180-room boutique-style hotel (the state’s first Hotel Indigo), 1,188 SF of meeting and event space, a Colorado gold rush-inspired rustic American restaurant and modern saloon (Hearth and Dram), a 216-stall parking garage and four floors of AA office space. 

Real Estate Development 

Co-developed by Hensel Phelps Real Estate Development and Portman Holdings, the hotel and office building site is located at the Northeast corner of 18th Street and Wewatta Street in Denver, CO. It is a vertical mixed-use project of approximately 300,000 SF. The ground floor provides core and shell retail space with separate lobby areas for the hotel and office functions, a restaurant with a bar, and meeting and hotel program space. Parking for the project is provided in the structure on levels 2-4. Levels 5-8 consist of 180 hotel rooms, and levels 9-12 comprise corporate office space. In addition to being part of the Ownership group, Hensel Phelps Real Estate helped source the project financing and provided local project management and owner’s representation throughout the project. The total Real Estate Development value for this project is $97,000,000. 


This project is located on a constrained, irregularly shaped site at the Northeast corner of 18th Street and Wewatta Street. Due to the limited space and the building’s size and stacking requirements, the site required careful coordination, site logistics, and efficient planning. The Hensel Phelps team self-performed over 15,000 cubic yards of concrete for the project.
