NEW YORK CITY — Columbia Property Trust has completed its acquisition of 149 Madison Avenue, a 12-story office building located in Manhattan’s Midtown South district. An undisclosed seller sold the 127,000-square-foot property for $87.7 million. The company is purchasing the property subject to a ground lease that expires in January 2018. At that time, Columbia plans to begin a comprehensive repositioning at the fully vacated building. Redgate will serve as project manager, Genslar as architect and Highland Associates as engineer for the renovation project.
