Kuhlman Building – Under Construction | Denver, CO

Transformational Urban Block


Sienna Sloans Lake, the Kuhlman Block redevelopment involves the acquisition and redevelopment of a 2.23 acre site into a residential mixed-use, mixed-income project located on “Block 3” of the former campus of the St. Anthony Central Hospital in the West Colfax neighborhood of Denver.

The mixed-use development program consists of: the adaptive reuse of the existing 6 story, 40,000 sf Kuhlman Building that will provide 49 affordable rental dwelling units; 25 market rate, 2 & 3 bedroom row-houses; and a 2,400 sf high bay café that will be co-located with a 3,500 sf public plaza at the northeast corner of the site. The adaptive re-use of the existing 5,800 sf gymnasium attached north of the Kuhlman Bldg. will be transformed into a restaurant space. A significant water quality feature / rain garden of 4,000 sf is centrally located on the block.


Implementing high-quality urban design, the adaptive reuse of the Kuhlman Building, and contemporary new row-houses and a cafe, will be a vibrant, active and attractive community that includes a diverse mix of housing and commercial uses to enhance the legacy of St. Anthony and strengthen connections to Sloan’s Lake and the existing neighborhood.
