Tre-domen Farmhouse

Tre-domen Farmhouse is a two-storey house built from local red sandstone rubble, with some areas rendered and others limewashed. The front features a Welsh slate roof, while the rear has concrete tiles. The house has an L-shaped plan, with a short wing that projects forward from the left side of the entrance front, which serves as a granary.

The entrance is accessed through a newly added gabled porch. Each floor has two 2-light casement windows with elliptical heads. The roof is steeply pitched, featuring a central stack with two flues set in a diamond pattern, and an additional triple-flued stack on the left gable. The right gable end is blind.

On the rear elevation, there are two small paned casements and a modern single-pane window on the ground floor, with three small paned casements above, the left one being smaller. The rear gable has one large modern window and a smaller older window below, along with a small paned casement above. The granary wing has a small window on the ground floor, while the front of the granary features a window below and an external stair leading to a plank door under a gabled hood above.

Inside, the Victorian interior remains unaltered and very plain, with simple wooden fire surrounds, a timber stair, and plain joinery. The overall layout of the house has also not changed.
