Northwood Ravin plans to build a 10-story office and retail building at the corner of Mangum Street and Jackie Robinson Drive, called 555 Mangum. It will be built in partnership with Akridge, a Washington, D.C.-based real estate development firm. Designs for the new 10-story office building, along with a second, mid-rise building with about 400 high-end apartment units, are still being planned. The project will include 225,000 square feet of total office space and up to 15,500 square feet of street-level retail space. Amenities planned for the building include a 2,500-square-foot athletic club for tenants and a rooftop lounge with terrace and conference facility that will have views into the Durham Bulls Athletic Park. The Cushman & Wakefield real estate brokerage firm is marketing the office space and CBRE-Raleigh is marketing the retail space on behalf of Akridge and Northwood Ravin. Construction began in fall 2016, with an eye to a late 2018 completion date.
