Garden Walls at Gwaenynog, including Mr Macgregor's Potting Shed

Late C18 kitchen garden walls with associated garden shed adjoining at the S corner. The walls surround an irregular 4-sided garden plot on all save the W sides and are of red-brown brick, laid in English garden wall bond. The walls are surmounted by flat stone copings and stand to their full height, ranging from 2.8m to 3.5m in height. In the centre of the eastern stretch is a wide segmentally-arched entrance with limestone imposts and key, and C19 boarded gates (sketched by Beatrix Potter). Adjoining to the S at the angle between the S and E stretches of wall, and facing the yard away from the garden, is a 3-bay carthouse block with slate roof and plain limestone piers; angled S gable and boarded modern doors to the left-hand bay.

In the centre of the N wall is a short section of cross wall. In the S wall is an iron half-gate leading to the service court; the section of wall to the R of this is of limestone rubble and is backed by a lean-to stable block, facing the yard, with 7 plain openings. At the SW corner, adjoining this, is Mr Macgreggor's Potting Shed. This is a long, low rectangular building in Rustic Gothick style and abuts the stable lean-to to the rear. Of limestone rubble construction with slate roof and tiled ridge. Entrance with recessed old boarded door to the W side. The garden-facing gable end has a rectangular 12-pane sash window to the ground floor with an arched, multi-pane Gothic window above; elongated stone voussoirs and opening metal casement section.

Mr Macgregor's Potting Shed has a plain beamed ceiling to the ground floor, with slate floor and ladder stair to the upper loft floor. Primary crude stone fireplace with grate.
