5 Rhiw Fach Terrace

5 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, with alternating buff stone used in the quoins. They feature slate roofs and rectangular stone chimneys that originally had four flues, complete with water tabling. The ground floor windows and doors have deep stone lintels.

Houses numbered 1 to 3 and 8 to 10 are designed as two-window homes, with upper windows positioned at the eaves and ground floor windows and doors aligned below. The door is to the right in all but No 1, which has its door to 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 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 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 in forecourts enclosed by low slate rubble walls, some of which have iron railings, and slate gate-posts. The partition walls of the forecourts are mainly 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 formed from upright slate slabs.
