Description
Blue Door Farmhouse is a white-painted, rubble-built farmhouse with a slate roof, constructed on a north-south axis in two unequal sections. The smaller, later addition is attached to the southern gable of the earlier section. There is a small lean-to on the west side of the original range and a larger lean-to at its northern gable. The original outer doorway at the south end of the 16th-century range has been covered by the later addition, so the main entrance is now a doorway at the north end of the east side, sheltered by a mono-pitched pentice roof that connects to outbuildings.
To the left of the doorway, the eastern portion features three ground floor casement windows (with three, two, and two lights), two two-light casements on the first floor, all with renewed glazing, and a small gabled dormer in the roof, offset to the left. The gable chimneys are also present. The rear (west) elevation has a small single-storey lean-to positioned right of centre, with two small windows above it, and two two-light casements to the left at ground floor and one above. The northern gable wall includes an attic window.
The added portion at the southern end is slightly lower and has a tall extruded chimney stack on its eastern side, flanked by two-light casements at ground floor only. Its southern gable wall features a narrow doorway near the left (west) corner, topped with a pitched slate canopy, and a triangular arrangement of two casements at ground floor and one above, all offset to the right. The western side has two similar windows at ground floor and one above to the left.
The walls of the 16th-century portion are approximately one meter thick. The principal room on the ground floor, which was the former hall, has four massive lateral beams with 16th-century moulding (two narrow rolls separated by a sunk chamfer) but no stops. There is a chimney breast at the southern end that measures 3.3 meters wide and 1.75 meters deep, with a staircase doorway on its western side and the former entrance lobby on its eastern side. This lobby retains the original massive Tudor-arched external oak doorcase and features a board door.
