Description
Old Blew House is an early 18th-century house located on Dulwich Common, Southwark. It has undergone later alterations. The house is rendered and has a pantiled roof hidden behind a parapet. It is three storeys high, with an irregular pattern of bays, including a three-windowed, canted bay on the right side. A timber Doric porch flanks the central door, which has pilaster jambs and a fanlight over it. The windows are sash windows with glazing bars, set in flush boxed frames. Extensions have been added to the left side, including a garage. The interior has not been inspected.
