An intriguing one-bedroom for sale in an 1890s mansion in the Bedford Historic District is an income-restricted HDFC co-op and has original details as well as recent updates. Built for a clothing executive and his family, the 1891 Romanesque Revival pile is dripping with columns and terra-cotta ornament. It was designed by architect Peter J. Lauritzen, whose other notable buildings include the Union League Club in Crown Heights and the Offerman Building in Downtown Brooklyn.
