Kitchen garden walls and former coach house (The Studio) at Plas Tan-yr-allt

The kitchen garden walls and former coach house, known as The Studio, at Plas Tan-yr-allt are located on a sloping site measuring approximately 90 meters north-south by 40 meters. The garden is enclosed by rubble stone walls that converge at the southern end. The western wall features an inner brick face. Both the eastern and western walls have pointed doorways; the eastern side includes a wrought-iron gate adorned with a quatrefoil and trefoils in the arch, which may have been made at Britannia Ironworks for Clough Williams-Ellis in the early to mid-20th century. In the northwest corner, there is a large stone water tank that was later converted into a swimming pool, featuring brick and render inner walls.

The northern side of the site is occupied by a former coach house constructed of rubble stone with a slate roof. This building has replacement windows and a door on the southern side that faces the garden. The northern side, which faces the drive to the house, retains its original openings, although the details have all been modernized. Additionally, there is a lower tack room added to the eastern side of the coach house.
