6 Rhiw Fach Terrace

6 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 in the quoins, and feature slate roofs with rectangular stone chimneys that originally had four flues each. 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 directly below. The door for each house is on 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 a higher eaves level and ridge. It 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 on the right side of 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 rendered and painted. Houses 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 enclosed by low slate rubble walls, some of which feature 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, are small gardens on land that slopes down to the stream, with walls also formed from upright slate slabs.
