This 36,000 sq. ft. Lower Downtown building was purchased in 1985 and was vacant at closing. Jerry condominiumized the building and sold two floors for residential and, later, office use, while retaining the lower three floors and the basement for offices. The renovation was completed in 1986 and Columbia Group continues to office in this building.

In the mid 2000’s Columbia Group acquired a series of buildings known as the Rocky Mountain Seed Buildings in Lower Downtown Denver.

After successfully renovating the two historic buildings, Columbia Group built a new building on an existing surface parking lot. Both the historic buildings and the new building have won several awards, including a Mayor’s Design Award, a Downtown Denver Partnership Award, a Urban Land Institute Award, and a National Award from the American Institute of Architects (AIA). These fully occupied buildings were sold to an investor in 2018.

In 1993 Columbia Group purchased, in partnership with the Denver Housing Authority (DHA), a vacant building at 15th and Blake Streets in Lower Downtown.

Columbia Group condominiumized the building into two units: a thirty ­three-unit income-restricted affordable housing project co­-owned with DHA and ground floor retail spaces.

In the fall of 2018, Columbia Group joined City Street Investors to develop a new 34,000 square foot office and retail building in the Highlands neighborhood in Denver. The project was completed in 2001.

In 2018 Columbia Group purchased a building at 38th and York Streets in the Clayton neighborhood of Denver. Originally part of Army Medical Depot, a complex of buildings constructed during the Second World War, it was designed by one of Denver’s most significant architects, Temple Buell.

Columbia Group repositioned the existing building to focus on nonprofit and local small business tenants.  A portion of the land which was acquired with the property was sold to a local arts nonprofit, Lighthouse Writer’s Workshop, and Fred oversaw the construction of their new headquarters on the site.  Columbia Group is working on entitlements for an additional site to enable the development of Colorado’s first LGBTQ+ senior affordable housing.
