A vacant building at 195 S. Washington Ave. could be demolished and replaced with a small public garden made partly from its salvaged materials, under a revised proposal submitted to Columbus’ Downtown Commission. The site is at the edge of an existing surface parking lot, about a block south of Topiary Park. The building has been boarded up for years. A demolition request submitted earlier this year proposed expanding the parking lot, but the commission rejected it, citing city guidelines that discourage demolition without an approved replacement plan and discourage additional parking in the central business district. The new application describes the project as a “Remolition”: a redesign of the site intended to preserve part of the building’s material history. It proposes using recovered wall brick as paving and planting low-maintenance ornamental grasses and ground cover. The application says further design work is needed for vertical features and landscape lighting. The applicant, Columbus architecture firm Blostein/Overly Architects, says the building has deteriorated beyond the point where renovation would be economically or commercially viable. The application also says the adjacent parking lot has already encroached on part of the property. The building and parking lot are owned by an LLC associated with Healthcare Realty Trust, a Nashville-based real estate investment trust that owns other nearby properties, including buildings at 500 and 515 E. Main St. For downtown demolition requests, commission approval is generally required unless the city has declared a building an immediate safety hazard. The commission has typically sought plans that replace demolished buildings with housing or commercial space rather than parking. The garden proposal would offer a different kind of replacement, though it does not call for new housing or commercial space. The Downtown Commission’s next meeting is scheduled for Oct. 27. The proposal remains subject to the commission’s review.
