Another of my favorite townhouses in the Back Bay neighborhood of Boston is this Victorian Gothic mansion on Beacon Street, built for Daniel and Mary Knowlton. The residence was designed by the firm of Allen and Kenway and built in 1880 and stands out architecturally for its use of style and use of material amongst a sea of brick. A former cotton merchant, Daniel Knowlton was treasurer of the Flexible Shoe Nail Company and later worked as a stockbroker. The large single-family dwelling was converted into four condominium units in 1989, but has since been switched back to a single-family residence. It sold for $11.2 million dollars as a five bedroom, six full and two half bath home in 2017. Yikes!
