Denver Single-Stair Housing Challenge

Buildner and SAR+ Architects are proud to launch the Denver Single-Stair Housing Challenge, the 18th competition in Buildner’s Affordable Housing Challenge series. This competition aims to address the housing crisis in Colorado by inviting innovative design solutions for mid-rise, single-stair housing.

The Denver Single-Stair Housing Challenge calls on architects, designers, and urban planners from around the world to reimagine the potential of PAB housing in the U.S. Participants are tasked with designing mid-rise buildings, up to six stories high, on underutilized lots in Denver. These designs should not only comply with the existing zoning and urban planning goals of Denver but also propose innovative solutions to overcome the regulatory barriers that currently hinder the implementation of single-stair housing.

Competition Site

There is no mandatory site selected for this competition. Participants can find and choose any underutilized, vacant site in Denver, Colorado, that is 6,000 square feet or less. The chosen site must be an open lot without any existing structures.

Alternatively, participants can use Buildner’s designated site located at 1338 Emerson St and currently exists as a surface parking lot. It is situated in the heart of the Capitol Hill neighborhood, benefiting from its proximity to key public transit routes along Colfax and 12th Avenues. This location aligns with Blueprint Denver’s vision of complete neighborhoods and integrated transportation networks.

Eligibility

Competition is open to all. No professional qualification is required. Design proposals can be developed individually or by teams (4 team members maximum). Correspondence with organizers must be conducted in English; All information submitted by participants must be in English.
