7 Rhiw Fach Terrace

7 Rhiw Fach Terrace is part of a row of houses located in Cwm Penmachno, within the Bro Machno Community. The buildings are constructed from squared dark stone rubble, with buff stone used in the quoins. They feature slate roofs and rectangular stone chimneys that originally had four flues, along with deep stone lintels above the ground floor windows and doors.

The houses numbered 1 to 3 and 8 to 10 are designed as 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, which has its door on the left. No 1 has been extended at the rear with flat slate rubble, resulting in higher eaves and a taller roof ridge, and it includes a window on each floor of the southwest return. No 10 features a basement due to the ground sloping down to the stream, with a door and two windows located to the right on the northeast return. The 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. Nos 1 to 7 retain 19th-century sash glazing, most of which still has the 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 of the houses largely maintains small pane glazing, either horned sashes or fixed panes.

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