Description

The Manor of Dean is a large house, formerly known as Dean House. The south and east wings at the rear are timber-framed, partly dating from the 15th century, with plaster and red brick infilling. It has a tiled roof and features casement windows. The building has two storeys and an attic, with three windows and two dormers. The main or west wing is dated 1613 and is constructed from stone. It has a projecting central gabled porch with a four-centred red brick archway and two storeys above. There are gables on each side of the porch, and round windows in the three gables, two of which are blocked. The roof was originally covered with Horsham slabs but has mostly been replaced with tiles. The casement windows have stone mullions and transoms, along with red brick dripmoulds. This wing has three storeys and three windows.
