Wonastow House

Wonastow House is a simple Regency-style building, featuring painted stucco and a shallow hipped slate roof with oversailing eaves. The house has a rectangular double-depth plan facing west, along with a southeast service wing that is the former house. The two-storey facade has three windows and includes a centrally located rectangular flat-roofed porch. This porch has a large segmental-headed opening at the front, which is now filled with a multi-paned sash window, likely a former doorway. The ground floor has two 12-pane sash windows, while the upper floor features three 9-pane sashes. A chimney stack is offset to the right, located behind the front ridge of the roof.

On the right-hand return wall, there is a curved, flat-roofed bay window. In the angle with the rear wing, a lean-to conservatory is attached to the front wall of the wing, covering a doorway and a window, and above this is a tripartite sash window. The south gable of the wing has an extruded former bread-oven, which is not visible from the inside, and a gable chimney.

Inside, there is a straight staircase with stick balusters and fluted architraves around the doorways. The dining room, located at the rear of the right-hand side, has long and low proportions and features two coved niches at the front end.
