No. 1 Brynhyfryd

No. 1 Brynhyfryd is the left half of a mirrored pair of houses, each featuring a painted rendered front with one window bay and an inner doorway. The houses have brick dentiled eaves and a slate roof, with No. 1 having tarred slates. The end-wall stacks are made of old red brick, with No. 2's stack built up in modern brick and shared with Cartref. The buildings are two storeys high with an attic. Each house includes a small gabled dormer with bargeboards and an iron casement pair window, as well as a long first-floor iron cross-window with small panes set back from the wall face.

The ground floor of No. 1 has a 20th-century window styled with four panes, one of which opens to the centre, and a half-glazed door to the right. No. 2 features a slightly lower head to its half-glazed door, which is immediately next to a two-light later 19th-century shop window with two plate glass panes set in a casing with piers, fascia, and cornice. At the rear, both houses share a broad central gabled wing with an old red brick chimney, two small casements in the attic, and two cross-windows with brick cambered heads and iron opening lights on both the first and ground floors. The south gable of No. 1 has a small leaded window in the attic and a larger leaded fixed light with a cambered brick head below.

The interiors of both houses are similar, featuring a ground floor front room with an exposed east-west beam and unchamfered joists. There is a beam over the partition between the houses, and the end-wall ground floor fireplace has a timber lintel, with a cupboard to the left that has a plank door. A diagonal door in the southwest angle leads to a rear lobby. There is a two-panel door to a small rear room, which has a panelled cupboard door on the south wall and a blocked corner fireplace. A cellar is located under the back wing. The enclosed narrow stair features a short length of railing with square pilasters and a thin rail on each side of the landing. In the attic storey, there is a timber-framed partition between the front range and the rear wing, and an iron column is present within the shop window of No. 2.
