CHICAGO — McShane Construction has completed the conversion of a former office building to 28 loft apartments at 2800 N. Milwaukee Ave. in Chicago. The 50,560-square-foot Hairpin Lofts includes apartment units on the top four floors, plus a 7,000-square-foot community center on the second floor. The ground floor features 9,000 square feet of retail space. McShane began reconfiguring the former Morris B. Sachs building in mid-2010. Crews restored the existing facade that dates back to 1930 and refinished the aging marble flooring. The building also includes sustainable features such as a green roof and Energy Star appliances. The project was co-developed by Brinshore Development and Anixer Center.
