Caerau including garden wall to front

Caerau is an early 18th century lofted single-unit cottage that features an added parlour wing on the right and a modern wing on the left, which replaced an earlier structure. The cottage is built of rubble masonry with a boulder foundation, rendered and limewashed. It has a roof covered with old small slates, heavily grouted on the older part, and stone gable copings on the right with cement copings on the left. The original extent of the house is indicated by a large chimney stack on the right gable and a false stack on the left, along with a stack on the right gable of the parlour and a matching false stack on the left gable of the modern extension.

The main entrance is now offset to the right of the large chimney and leads into the parlour bay. It features a boarded door with a glazed upper panel, flanked by unevenly spaced recessed four-pane casement windows, with the left window originally serving as the doorway to the original cottage. A raking half-dormer above has a two-pane casement window with a small upper light. The rear elevation of the original cottage includes a widened four-light 'picture' window, with each window containing narrow eight-pane sash windows separated by timber mullions. The parlour window on the left is a recessed four-pane casement that retains its original proportions, while the modern addition on the right has two closely set twelve-pane sash windows. There is also a small iron skylight on the rear pitch.

In front of the older part of the cottage is a low stone wall that encloses a rectangular garden with rounded corners, featuring two entrances with wrought iron gates. Originally, the plan was for a single-unit crogloft cottage with a central offset doorway. The current entrance leads into the parlour bay on the right, with a passage on the left leading to the original part and a steep wooden staircase to the loft. Inside the original section, there is a wide inglenook fireplace on the right end, with a stop-chamfered ceiling beam and hewn joists. The roof consists of two bays with a crude collared truss made from reused timbers. There is a second entrance to the newer bay on the left, which also provides access to the original part.
