Location: Cincinnati, OH Customer: 3CDC Construction Schedule:January 2019 – December 2019 Size: 32,000 SF Architect: GBBN HGC collaborated with long-time partner 3CDC on this 32,000 SF historic renovation. The Columbia Building is a historic building at the corner of 13th and Walnut. The area has already seen a large amount of redevelopment led by 3CDC, and the completion of this critical corner only further energizes the vibrant neighborhood. The final result is 36 apartment units with street-level commercial space. Check out another high-profile collaboration with 3CDC Due to the scope of the project, the building was split into phases: the North Building and South Building. Both buildings were separated by different stairwells. This allowed the teams to complete units moving from top floor to bottom floor, and work their way out the stairwell. The logistics were challenging due to the constrained urban site and limited lay down area. HGC utilized the basement for the office and staging area. The four commercial spaces on the ground level became storage and lay down area for the duration of the project. These spaces were the last to be finished. The South Building was finished first and delivered to tenants, while work was completed on the North Building about two months later.
