Pen Dyffryn

Pen Dyffryn is a two-storey brick building with a slate roof, featuring a main block of three bays and a central entrance. At the rear, there is a service wing that includes a coach house and an arched entry leading into a stable yard, which is enclosed by the stable wing and creates a courtyard behind the house.

The entrance front showcases a central doorway set within a latticed wood porch topped with a swept leaded roof. The doorway is framed by a moulded architrave. To the right of the entrance, there is a squared tripartite bay window, with three similar sash windows located above it. A single-storey extension was added to the left in 1943. The eastern elevation features a small triangular oriel window on the upper storey, followed by a two-window range service wing that is set back. The coach house block is attached to this wing at the rear and includes a segmental archway that leads to the rear yard. The stable block in the yard is partly constructed from red sandstone blocks, indicating that it may have been built around an earlier structure on the site. This block contains a small single-unit cottage with a tiny angles fireplace.

Inside, the central entrance hall is divided by a moulded plaster arch, with a staircase leading towards the rear. The staircase has turned balusters and a swept rail. Throughout the building, there are reeded doorcases, and several original decorative cast iron fireplaces remain in the upper rooms.
