Description
Porth Farmhouse is a farmhouse, now divided into two units, dating from around 1800. It features slatestone rubble walls and a scantle slate roof that slopes lower at the rear, with brick chimneys on the gable ends. The building has a two-room, double-depth plan with a staircase on the right side between the front and rear rooms. It is two storeys high and has a nearly symmetrical three-window south front. There is a 20th-century glazed door in the original opening, which is slightly off-centre to the right, with a window above it. All windows are 16-pane sashes in their original openings, topped with cambered brick arches. The rear also has three windows, and there is a 24-pane sash window for the stairs in the east side wall. The interior is simple, featuring an original dog-leg staircase and a two-panel door on the ground floor. The first floor and roof have not been inspected.
