Bennink-Douglas Cottages
 The Bennink-Douglas Cottages are a collection of four historic workers' cottages on 35-51 Walker Street in Cambridge Massachusetts. The four nearly identical mansard-roofed Second Empire cottages were built in 1874 as a speculative venture by Gerritt Bennink and William Douglas for sale as low-to-middle-cost housing for workers. Their style was typical of low-cost housing built during the 1870s throughout Cambridge.
