Garden walls at Tan-y-bwlch

The garden walls at Tan-y-bwlch were built to enclose orchards and a kitchen garden. They are made of in-situ no-fines concrete, 230-250mm thick, using crushed slate waste aggregate, and were constructed in lifts of about 60cm. The walls are on average 3 meters high, reaching up to 4 meters in some areas, forming a large sub-rectangular enclosure approximately 10 meters by 12.5 meters. The northern end of the enclosure is subdivided by cross walls into two smaller areas. The walls do not have provisions for linear movement, and the daywork joints are not clearly visible. However, there are occasional door openings with timber doorframes cast into the walls, along with straight and low triangular timber lintels. On the northern side, the wall is situated at the edge of a river terrace and features two small buttresses made from the same material. The walls are otherwise not horizontally restrained. At the southwest corner, near the northwest corner of the farmyard's northern range, there is a small attached stone-built structure that contains a privy and boiler room, topped with a slate roof. Additionally, on the northeast corner of the gardens, there is a small rectangular structure that is now roofless and located outside the line of the walls. While the walls have toppled in some places, likely due to wind pressure, they have generally remained in remarkably good condition.
