SALT LAKE CITY, Utah — The Wells Fargo building in the center of the Sugar House urban core is set to be sold at the end of the month to a buyer that is likely to construct a mid-rise residential building, Building Salt Lake has learned. …If it’s finalized, the buyers intend to build what would be Salt Lake City’s first mass timber residential project. …Renderings aren’t yet available, and the developers would need to go through the design review process that’s required for all new buildings of significance in the Sugar House Business District. If they receive city approval, the builders would be allowed to construct a building up to 105 feet tall on the corner, or about nine stories. It’s unlikely the project moves forward before 2024.
