Description
Portway House is a substantial house dating from 1684, as indicated by a datestone, with an extension added in the early 20th century. The building is constructed of coursed squared limestone with ashlar dressings and features roofs made of concrete plain tiles, old plain tiles, and Stonesfield slate, along with rubble and brick stacks. It has an L-shaped plan and stands two storeys high with attics.
The garden front has three windows and the entrance is located to the left of centre, below a blocked two-light stone-mullioned window. The outer bays feature three-light leaded mullioned windows. A sundial with a rectangular moulded frame is inscribed with "TW AW/1684". A moulded string course runs above the entrance and returns to the left. The roof includes three gabled dormers, a gable stack on the right, and is hipped to the left, extending over the long rear wing.
To the left, there is a three-bay elevation with six windows that dates from the 17th century, featuring similar three-light mullioned windows, with the central windows illuminating a stair and cutting across the string course. The extension of this range is in a similar style and incorporates an earlier single-storey range. The main entrance is now located at the angle of the two ranges. The interior has not been inspected.
