Craig-y-castell

Craig-y-castell is an enlarged house built from local limestone, featuring masonry that is either rubble or axe-dressed and informally coursed. The house has coped gables and a slate roof with a tile ridge. On the north elevation of the original main range, there is a dormer that includes a 2-light Tudor window with segmental heads, iron casements, and a ventilator.

The other windows of the house reflect various recent phases of enlargement or alteration. On the front (north side), the newer windows are generally made of stone, with quarry-glazed glass, mullions, and label moulds. At the rear, the windows are mostly timber casements.

The front of the house features an advancing 2-storeyed gabled wing. To the left, there are a pair of less-advancing upper-storey gables and a single-storey crenellated ground storey. To the right, there is a gabled porch with a flight of steps and a canted, crenellated extension on its side. The house has a large axial main stone chimney, a later similar chimney to the left, and a modern lateral stone chimney at the right corner.

On the south elevation, a stone carved with the Welsh Dragon has been inserted into a gable. The dragon is depicted in a roundel, shown in modern convention as passant, with wings raised and tongue and tail barbed. Also set into the south gable of the drawing room wing is a slate sundial featuring a simple iron gnomon and painted Roman numerals, supported by two carved heads.

Inside, two rooms of the main range, located west of the main hearth, have beams and joists with similar stops, including broach stops on the main beams and simple stops on the joists.
