BOULDER — Big changes could be around the corner for the Macy’s department store on 29th Street in Boulder.

During the Boulder Valley Real Estate Conference held Thursday in Boulder, several panelists mentioned plans to redevelop the store into office space.

The brochure describes the project site as “repurposed infill,” which suggests the office space could be built out of the existing Macy’s structure rather than demolishing the store and rebuilding.

Boulder29 could be three stories with 17-foot ceiling heights, according to the brochure, which does not mention Macy’s by name. The first and second floors could have 62,500 square feet of floor space, and the third could have 25,000 square feet.

The project could include 570 parking spaces, rooftop decks, collaboration spaces, a courtyard and a fitness center.

The timetable for the potential Macy’s closure and redevelopment is unclear.

Calls to Macerich (NYSE: MAC), which manages the Twenty Ninth Street commercial area, were not immediately returned, nor were calls to Corum Real Estate Group, which is listed on the brochure as the project’s developer.Cushman & Wakefield officials referred questions about Boulder29 to Macy’s representatives, who did not immediately provide a comment.

Boulder County public records show the 36-year-old building at 1900 29th St. is still owned by Macy’s. Development plans have yet to be submitted to the city.

The property is zoned Business Regional – 1, which, according to Boulder city code, allows a “wide range of retail and commercial operations, including the largest regional-scale businesses.”

In 2016, Macy’s Inc. (NYSE: M) announced plans to close about 100 stores over a period of a few years. Dozens of those locations have been disclosed by the company, but none of the stores in the Boulder Valley or Northern Colorado have been included on the closure lists. Macy’s has stores in Boulder, Loveland, Broomfield and Fort Collins.

Former Macy’s stores across the country are being redeveloped, some into office space, according to media reports. In locations, including Brooklyn, Chicago and Seattle, where Macy’s had multi-story buildings in downtown areas, the company has sold off upper floors to be turned into offices.
