MINNEAPOLIS — A joint venture between TriCoastal Group and The Davis Companies has acquired Renaissance Square in Minneapolis for an undisclosed price. The companies plan to renovate the 140,000-square-foot office building and rename it The Andrus in homage to the building’s first owner, John Emory Andrus. The scope of the renovation includes a new street-level façade and retail space, a new tenant lounge, upgraded lobby and conference facility. RSP Architects will manage the design and renovation work for the 11-story building. Construction is expected to begin this summer and be completed by early 2019. Cushman & Wakefield is providing leasing, property management, engineering and construction management services. WSP, Sedgwick, Cue Inc., Genus Technologies, Fastbridge, CBX and DLR Group currently occupy the property, which first opened in 1898.
