Plas Tregayan

Plas Tregayan is a house with a significant early 17th-century core, substantially expanded in the early 19th century. The original section formed the servants’ hall and service wing, to which an L-shaped main house was added at right angles, and subsequently extended with single-pitched additions. The house is constructed from rubble masonry, with the older section potentially retaining some timber framing, all rendered with roughcast. The roof is covered in large slates laid in diminishing courses, and features tall, rectangular stone stacks with dripstones and capping.

The main part of the house is a two-storey, attic structure with a three-window front. It has a smooth-rendered plinth and a first-floor sill band. The central doorway is framed by a smooth-rendered architrave and has double doors, topped by an arched fanlight with radiating glazing bars. The windows are tall, two-pane casements, and the attic windows are barred. The shallow-pitched roof includes tall gable stacks. The north gable return has a single first-floor 12-pane hornless sash window to the rear, and continues as a full-height wing with a two-storey, single-window wing at the west end; both wings have tall gable stacks. The full-height wing has French doors on the ground floor, a 16-pane hornless sash window on the first floor, and an unequal hornless sash window in a hipped-roofed gable dormer. The two-storey wing features a ground-floor 16-pane hornless sash window and a tall 16-pane casement above.

The south gable return, set at a right angle to the older part of the house, has a four-window range of 12-pane hornless sashes, with openings offset to the right. There is a gable stack and a lateral stack to the right of the second window. The entrance to the former servants’ hall is positioned below the third window, and a raking dormer sits above the fourth. Single-storey, single-pitch additions have been built to the west end and to the rear, connecting to the north wing of the early 19th-century house; these additions primarily feature two- and four-pane sash windows.

The doorway to the older part of the house opens into the former servants’ hall, which retains a large chamfered beam and bressumer over the fireplace in the southwest corner. The north wall of this room is believed to be timber-framed, and the wall of the adjoining room displays exposed, diagonally set, timber framing. The central doorway to the main part of the house leads into a wide central hall, flanked by principal rooms beyond large sliding doors. These rooms have moulded covings, and the sitting room has a marble fireplace with chamfered angles. The dog-leg staircase has a plain rail on stick balusters and leads up to the rear of the house, where the upper hallway features a circular skylight with coloured glass and an ornate moulded surround. Some doors have moulded architraves, and some attics retain 17th-century six-panel doors. Several upstairs rooms have chamfered beams with moulded stops, retain simple marble fire surrounds, and mostly retain panelled window shutters.
