Hines Kicks Off Office-to-Residential Conversion

The finished product will offer more than 200 units.

Hines has started construction on its first office-to-residential conversion, which will transform South Temple Tower, a 217,000-square-foot office building in Salt Lake City, into a 217-unit community. Dubbed Seraph, the 25-story tower is scheduled for delivery in the fall of 2025.

South Temple Tower originally came online in the 1960s. Hines acquired the property in June 2022 from a lender who foreclosed on the asset. Last November, the company took out a $90 million loan from Athene Annuity & Life Co., according to Salt Lake County records.

The conversion will involve the removal of a significant portion of the façade and the addition of floor-to-ceiling glass. Additionally, the adaptive-reuse development will reduce embodied carbon by limiting new construction materials used.

Designed by architecture firm Hickok Cole, the high-rise will comprise studio, one- and two-bedroom apartments, along with three-bedroom penthouses. The community is expected to include a seventh-floor amenity deck with a swimming pool and hot tub, clubroom, fitness center, dog run and pet spa, as well as an indoor lounge and rooftop deck with firepits and grills. Plans also call for a game area and parking structure.

The transit-oriented property is at 136 E. S. Temple St., 1 mile from downtown Salt Lake City. City Creek Center shopping mall and Temple Square are also nearby. Salt Lake City International Airport is less than 7 miles northwest of the development. The location is also roughly 2 miles from a 580-unit project developed by Bridge Investment Group and Lowe Property Group.

Hines’ multifamily expansion across the U.S.

Hines’ portfolio currently comprises $48.5 billion in assets under management spread across 118 cities around the U.S. The firm’s multifamily portfolio totals 85 communities and a single-family rental development, according to Yardi Matrix information.

One of Hines’ recent projects is Food, Art and Technology Village, developed in a joint venture with Urban Street Development. The partnership broke ground last month on the master-planned campus in Fort Lauderdale, Fla. Rising on 5.6 acres, the mixed-use project will include more than 850 residential units, office space and 80,000 square feet of food, retail, entertainment, art studios and galleries.

The firm also landed $58.7 million in construction financing in November for Retreat at Mountainside in Colorado Springs, Colo. The 284-unit luxury community, developed in partnership with MBK Rental Living, is scheduled to come online next year.
