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

On a sloping site and approximately 90m N-S by 40m, the garden is defined by rubble stone walls which, on the E and W sides, converge at the S (downhill) end. Part of the W wall has an inner brick face. E and W walls have pointed doorways, which on the E side has a wrought-iron gate with quatrefoil and trefoils in the arch (also used at 4 Church Street, Tremadog, and possibly made at Britannia Ironworks, which produced architectural ironwork for Clough Williams-Ellis in the early-mid C20). In the NW corner is a large stone water tank, later used as a swimming pool, with brick and render inner walls.

The N side is occupied by a former coach house of rubble stone and slate roof. It has replacement windows and door to the S side facing the garden. Its N side facing the drive to the house, retains original openings but the details are all modern. On the E side is an added lower tack room.
