Ty Gwyn Outdoor Education Centre

Ty Gwyn Outdoor Education Centre is a late Arts-and-Crafts style former convalescent home that stands 2½ storeys tall. It features pebble-dashed walls and graded slate roofs with projecting eaves, hipped at the right end, and brick chimney stacks. Most of the windows are horned sashes. The building has a long range built across a slope, with the entrance located towards the left end between lower wings that are splayed at 45-degree angles, creating a symmetrical composition reminiscent of early 20th-century Arts-and-Crafts designs.

The gabled entrance bay has a doorway on the right side, which is recessed inside a round-headed arch made of brick voussoirs, and it features replacement double doors. To the left of the entrance is an 18-pane window, with a similar window above it on the upper storey, and a tripartite window to the right. The attic includes a 4-light small-pane casement window. The wings have 8-pane windows on each storey and two 8-pane windows in the gable ends, which flank shallow external stacks. Further to the right, the main range has three French doors with small-pane glazing and overlights, while the upper storey features 12-pane sashes beneath small-pane fixed lights.

The right end wall has two wide round-headed small-pane windows in the lower storey, a 12-pane window in the upper left, and an inserted escape door and stairs in the upper right. The rear of the building includes large inserted windows from the 1960s alongside original horned sashes. There is a gabled projection to the right of centre, with superimposed stair windows to its right. Further to the right is a parallel rear wing that originally housed the intensive care unit, which shares similar detailing with the main range, and has a hipped lean-to on the front side that contained the original pantry. The left gable end of the main range has a combination of 12-pane and 8-pane windows, along with a replacement attic window.

Inside, the entrance foyer features an open-well stair with plain balusters and newels, and scrolled tread ends. The interior has been altered, but originally, the kitchen was located at the left end, adjacent to the dining room, with a classroom at the right end.
