Description
Red House is a one and a half storey building with close studding up to the loft level and square panels above. The garden front features a small 19th-century gabled dormer that replaces an original 17th-century one. The building has been extended by one bay to the west, maintaining the close studding. A large contemporary timber-framed gabled dormer with a four-light casement window is present. The west end wall is constructed of late 19th-century brick and includes a chimney. The ground floor has 19th-century casement windows, and there is a blocked 17th-century window in the later bay. The roof is covered with late 19th-century red tiles, hipped to the west, and features fishscale bands, terracotta gable finials, and bargeboards. A contemporary chimney with triple flues is also present.
The late 17th-century crosswing has close studding, a mid-rail, and corner braces. It is a double pile on the north side and has been re-fronted in brick on the south. The east elevation has two windows, with two-light cross windows on the first floor and a three-light transomed window to the left on the ground floor, alongside a cross window to the right. A 19th-century lean-to porch with a gablet and a panelled door is located at the centre. The north side features 19th-century fenestration that replaces the original symmetrical 17th-century tiers. The roofs are gabled with red tiles, and there is a brick stack with twin flues. A lean-to porch is inset at the angle on the rear.
Inside, there is an early 18th-century staircase with turned balusters.
