Upper Dorval House

Upper Dorval House is a detached house built around 1902 or 1903 by the architect Ernest Barnsley, featuring a late 17th-century core. The building is constructed of rubble stone with smooth stone dressings on the end wings and has a Cotswold stone-slate roof. There are two stone stacks on the central section and one gable stack on each wing. The original central section is two stories high and has a three-story cross gable wing to the left that extends back, while the two-story cross gable wing to the right extends forward, with an additional two-story wing to the south that continues the line of the original section.

A large gabled porch is present on the central section, featuring a stone tile-hung gable. The central section has three windows, including twin leaded casements, and three windows on the ground floor with a continuous wooden lintel over the two to the left of the porch. The windows on the right wing are small pane timber casements under wooden lintels, with a two-light window in the cross gable and a three-light window below. The left wing has plain chamfered two-light stone-mullion leaded casements under a straight drip mould. Both of Barnsley's added wings feature slit vents in the gables.

Inside, the central section boasts a very fine plaster ceiling designed by Ernest Gimson. Many original doors, complete with their latches, window seats, panelling, and the main stairs remain intact. Ernest Gimson and the Barnsley brothers, Ernest and Sidney, moved to Sapperton around 1902 after living in the area for several years. Each built a house for themselves in close proximity to one another, and all three houses still exist today. Of these, Ernest Barnsley's house is the least altered on the outside and retains a significant number of original features.
