8 Rhiw Fach Terrace

8 Rhiw Fach Terrace is part of a row of houses numbered 1 to 10 located in Cwm Penmachno, within the Bro Machno Community. The buildings are constructed from squared dark stone rubble, alternating with buff stone used in the quoins, and feature slate roofs. Each house has rectangular stone chimneys with water tabling, originally designed with four flues, and deep stone lintels above the ground floor windows and doors.

Houses numbered 1 to 3 and 8 to 10 are two-window homes, with the upper windows positioned at the eaves and the ground floor windows and doors aligned directly below. The door is located to the right, except for No. 1, where it is to the left. No. 1 has been extended at the rear with flat slate rubble, resulting in a higher eaves level and ridge to the roof, and features a window on each floor on the southwest return. No. 10 has a basement due to the ground sloping down to the stream, with a door and two windows to the right on 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 decorative render around their windows and doors, while No. 6 is fully rendered and painted. Houses 1 to 7 retain 19th-century sash glazing, most of which still have their marginal glazing bars intact, 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 elevations largely maintain small pane glazing, either horned sashes or fixed panes.

The houses are set within forecourts that feature low slate rubble walls, some topped with iron railings, and slate gate-posts. The partition walls of the forecourts are primarily made of upright slate slabs. Across the lane from the front of the houses, there are small gardens on land that slopes down to the stream, with walls also constructed from upright slate slabs.
