1 Rhiw Fach Terrace

Nos 1 to 10 Rhiw Fach Terrace in Cwm Penmachno, part of the Bro Machno Community, are a row of houses constructed from squared dark stone rubble, interspersed with buff stone in the quoins. They feature slate roofs and rectangular stone chimneys with water tabling, each originally having four flues. The ground floor windows and doors are topped with deep stone lintels.

Houses numbered 1 to 3 and 8 to 10 are two-window homes, with upper windows positioned at the eaves and ground floor windows and doors aligned below them. The doors are typically on the right side, except for No 1, which has its door on the left. No 1 has been extended at the rear with flat slate rubble, resulting in a higher eaves level and ridge. It also has a window on each floor on the southwest return. No 10 features a basement due to the drop in ground level towards the stream, with a door and two windows on the right side of the northeast return. Houses numbered 4 to 7 are double-fronted, each with three first-floor windows and a central doorway flanked by windows. Nos 4 and 5 have some decorative render around their windows and doors, while No 6 is fully rendered and painted. Nos 1 to 7 retain 19th-century sash glazing, most with intact marginal glazing bars, whereas Nos 8 and 10 have replacement glazing.

At the rear, there are various extensions, including an unusual contemporary attached parallel gabled block to Nos 3 and 4. The rear of the houses largely retains small pane glazing, either horned sashes or fixed panes.

The houses are set in forecourts with low slate rubble walls, some featuring iron railings, and slate gate-posts. The partition walls of the forecourts are mainly made from upright slate slabs. Across the lane from the front of the houses, there are small gardens on land sloping down to the stream, with walls constructed from upright slate slabs.
