Description
Penbryn House is a pair of three-storey houses, each with three windows and a one-window extension at the west end. They are constructed of coursed rubble masonry and feature moderately pitched slate roofs with cavetto eaves cornices and close verges. The buildings have stone stacks and water tabling.
The houses have later 19th-century gablets over the outer windows on the top storey, complete with bargeboards. The windows are twelve-pane sashes, with a dummy window set under the eaves in the centre. The glazing bars are painted on the window of Penbryn Croft. The first floor also has twelve-pane sashes with stone lintels and sills, and a dummy window in the centre. The ground floor has similar fenestration, with a central doorway. The doors are modern, and Penbryn House features a lattice rectangular fanlight. Above the doorways are slate tablets with inscriptions: "Built by T G E 1808" for Penbryn Croft and "Built by R O J 1808" for Penbryn House.
