Valley House with Conservatory on Left

Valley House, with a conservatory on the left, is a house dating from the late 18th century, featuring later additions and alterations, including a late 19th-century conservatory. The building is constructed of partly-rendered rubble with some brick infill, topped with a pantiled roof and brick chimney stacks. The conservatory is made of glazed wood. The entrance to the house is located at the rear.

The house is two storeys high and has four windows. It features flush quoins on the left and scattered fenestration, including two replaced sash windows and a canted bay window on the ground floor to the right. Above, there are two 12-pane sashes and two 24-pane sashes, with horizontally-sliding 6-pane sections. A lead sundial, shaped like a grandfather clock, is positioned above the central ground-floor window and features raised putti, the motto "TEMPUS FUGIT," and a segmental top with a date that may read 1774. The roof has raised eaves and verges, with old brick end and ridge stacks that have been rebuilt at the tops.

The gable-fronted glazed conservatory on the left return has a canted front entrance bay. At the rear of the house, there is a low two-storey outshut, with a six-panel door and a four-pane overlight to the left of the outshut. The interior includes early 19th-century panelling from Coniscliffe Hall. At the time of the survey, the conservatory was in a derelict state.
