Upon merging with Meridian Heights, the presbytery-owned building became the Presbyterian Metropolitan Center as a home to many non-profits. Over the years it slid slowly intro disrepair. Neighbors and preservationists rallied around the vacant building, and in 2000 philanthropist Jeremy Efroymson purchased it with the intent of creating an art center. Major repairs to the plumbing and roof stabilized the structure, and it opened as the Harrison Centre, a home for several relocated nonprofits, including VSA Arts, the Nature Conservancy, and the Herron School of Art.

In 1957 the organ of the church was replaced by a new one, again from M.P. Moller Inc. of Hagerstown, Maryland. The project was part of a renovation of the church because it had decided to remain downtown-for the time being. The contract for opus 9018 was dated July 9, 1956, to be completed by September 1, 1957, at a cost of $58,950.00. A memorandum dated December 6, 1956, from the church to the builder provided for some preparations to be included for an additional $1,500.00. The console was of stopknob control. A new fifteen-horsepower Kinetic blower was provided. The tonal design was by W. Curtis Hughes, First Church organist, and Robert Talbert, Moller representative. The instrument demonstrates influences of Ernest White's work for Moller at nearby Christ Church Cathedral (opus 8602) and Saint Paul Episcopal Church (opus 8539). -- 2007 OHS Atlas
