3 Rhiw Fach Terrace

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

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 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. It also features a window on each floor on the southwest return. No 10 includes a basement due to the sloping ground leading down to the stream, with a door and two windows to the right on the northeast return. Nos 4 to 7 are double-fronted, showcasing three first-floor windows and a central doorway flanked by additional 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 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, featuring either horned sashes or fixed panes.

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