CBRE has arranged the sale of the Villita Assembly Building, a 24,785-square-foot event center along San Antonio’s River Walk, to GrayStreet Partners, a local private-equity firm, for $5.3 million.

CBRE’s Andrew Price negotiated the transaction on behalf of the seller, CPS Energy, San Antonio’s municipally-owned electric and natural gas utility.

Located at 401 Villita St., the free-standing building was constructed in 1958 and sits on a 1.113-acre parcel. The single-story, circular building was designed by architect O’Neil Ford and features a concave rotunda wrapped with administrative, service, and mechanical spaces and adorned with custom decorative tile and carved stained-wood entry doors. The property includes a banquet hall, kitchen and outdoor plaza area.

The building is situated along the River Walk and adjacent to La Villita Historic Arts Village in Downtown San Antonio. It is within walking distance of many amenities and points of interest, including the Alamo, Henry B. Gonzalez Convention Center, Hemisfair, Tower of the Americas, Shops at Rivercenter, and numerous restaurants and hotels.
