Old Brook House

Old Brook House is a 17th-century house located on Pertenhall Road in Brook End, Keysoe. It features a timber frame with brick and colour washed plaster infill, topped by an old clay tile roof, which has rows of fish-scale tiles just below the ridge. The building has a T-plan layout, consisting of a two-storey cross-wing and a main block that is one storey with attics. The cross-wing has a gable end with 20th-century casement windows and a door, along with a half-hipped roof. The main block has three windows on the ground floor and two gabled dormers, all fitted with 20th-century casements. The right-hand bays are set at a lower level and have less substantial timbering, suggesting they may be of a later date. A red brick double ridge stack is present on the roof.
