Macy’s Renovation – Boulder

Horizon Glass manufactured and installed the curtain wall, entrance, and glazing scope for Boulder 29, the adaptive reuse of a former 155,000-square-foot Macy’s department store on Boulder’s Twenty Ninth Street Mall into a Class A creative office building. Designed by Shears Adkins Rockmore (SAR+) and built by Saunders Construction, the project recladded and renovated the roughly 40-year-old big-box structure and added a third level, transforming a windowless retail box into a daylight-filled office building with large floorplates, rooftop terraces, and exceptional views of the Boulder foothills and Flatirons.

Horizon’s scope encompassed approximately 50,000 square feet of Kawneer 1600 SS curtain wall, along with NanaWall operable glass wall systems and all glass doors—the high-performance glazing that gives the formerly skin-less building its light, transparency, and connection to the surrounding 29th Street retail district. Completed in 2024, Boulder 29 achieved LEED Gold certification.
