10 Rhiw Fach Terrace

10 Rhiw Fach Terrace is a row of houses located in Cwm Penmachno, within the Bro Machno Community. The buildings are constructed from squared dark stone rubble, alternating with buff stone in the quoins, and feature slate roofs. Each house has rectangular stone chimneys with water tabling, originally having 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 upper windows positioned at the eaves and ground floor windows and doors aligned below. The door is to the right for most houses, 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 on the roof, with 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 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 maintains 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 composed of upright slate slabs. Across the lane from the front of the houses are small gardens on land sloping down to the stream, with walls made from upright slate slabs.
