Cwm Hesgyn

Cwm Hesgyn is a long single-storey house with an attached cowhouse, built from local rubble with boulder foundations and situated on a downhill slope. The house consists of two sections, with the right section stepped down and a byre section adjoining the lower left end. The upper section has a slated roof, while the two lower sections are covered with corrugated iron; all parts except the cowhouse are whitened.

The entrance, located off-centre to the left, is a former window that now features a small pane glazed door. To the right of this entrance is a near-centre window, which was previously the main entrance. There are two additional windows at the far left and right, all of which are modern wooden casement types. A rubble end chimney is located on the right side, complete with weathercoursing.

The stepped-down section on the right has an entrance to the left, accessed by rough slate steps leading up to a short flagged terrace. To the right of this entrance are two late 19th century or early 20th century six-pane part-casement windows. The cowhouse features a single entrance to the left, and at the lower gable end, there is a lean-to structure known as Ty Bach. The upper gable end has a loft opening with a modern four-pane window, and there are additional windows on the rear of each section of the house, with the upper part having a ground-level window that features an expressed timber lintel.

The interior has been largely modernised but retains evidence of a former crog loft in the upper section and a stepped internal stack in the lower section. The building features simple pegged collar and tie-beam trusses, with a single tie-beam truss in the cowhouse.
