Description

Pen-y-Pentre, also known as The Old Factory House, is a three-window house with one and a half storeys, dating from the 17th century. It features an adjoining barn to the west and a rear lean-to. The exterior is pebble-dashed with a steeply pitched slate roof and stone stacks on the left, right, and right of centre. The front of the house has three wide, gabled half-dormers and two doors: a wood-planked door to the right of centre and a 20th-century half-lit door to the left of centre. The doors are situated between three ground floor windows, arranged asymmetrically, with the right-hand window offset further to the right. The windows have flat heads and stone lintels, with 4-over-8-pane sashes on the ground floor and 3-over-6-pane sashes on the first floor.

On the east gable, there is a multi-pane window that is off-centre. The rear of the house features a two-casement window. The long added lean-to at the rear is also pebble-dashed, covered by a corrugated roof with a red brick end stack. It has a 20th-century half-lit door in the centre, flanked by two-light casement windows, along with another similar window at the east end.

The adjoining barn is slightly lower and constructed of limewashed rubble masonry beneath a slate roof. Its front has double planked doors under a long timber lintel, with an additional single door to the left. The west gable end contains a small wood-framed opening in the apex, which may have originally featured timber mullions.

The interior of the house has been modernised. Entry is through the left door, leading directly to the stairs, with the living room to the left. A fireplace is located on the left wall, and former fireplace stairs are said to curve around to its north, although they are now covered. In the living room, there is one cross beam without chamfers, which has hooks for hanging meat.
