Ty Mawr

Ty Mawr is a house dating back to the 16th century, with later additions and alterations, situated within a small service courtyard. The original section is a rectangular 2-room plan with a through-passage, extended in the 18th century at a right angle to form a T-shape. Various 19th-century outbuildings are attached to the courtyard.

The external appearance combines roughly coursed rubble stone on a boulder plinth, with rendered gable ends, slate stone and brick additions, and slate roofs with slate-coped verges. The front (west) elevation has 19th-century casement windows in earlier stone surrounds on the first floor, above a full-length glass verandah supported by stone end walls and a cast-iron column with a glazed bay, creating a porch over the original entrance. The entrance itself features a round-headed doorway with chamfered jambs and run-out stops under a stone label. Below are 19th-century multi-paned horizontal sliding sash windows, all with slate cills and drips. A pair of half-glazed doors with margin lights are located to the left of the entrance, accessed via a porch with a return. Dormers punctuate the roofline, and rebuilt internal end stacks are present. A projecting stone garderobe is situated on the left of a stack on the first floor of the right gable end, alongside a small 2-light horizontal sliding sash window on the ground floor. The rear elevation exhibits a similar doorway to the front, lacking a stone label, and a horizontal sliding sash window set in a wide opening with a projecting slate lintel as a drip. A large 19th-century 3-light mullioned and transomed timber window is located on the first floor, immediately to the right of a lower projecting range which has an eaves window and an integral end stack.

The ground floor likely originally comprised a large room to the north of the passage, and two smaller rooms to the south. This division remains visible; the northern room incorporates a large, infilled fireplace and plastered beams. A chamfered beam with peg-holes for a timber partition is present in the south side of the slate-floored passage. The passage joists are chamfered with concave stops, while those in the two south rooms are roughly chamfered. A stone staircase with slate treads is located in the northeast corner, with a blocked window to the east. The first floor, initially open to the roof, features a chamfered beam and chamfered and stopped joists in the north room, a straight flight of 19th-century stairs to the centre, and a slate stair to the southeast corner, both leading to an inserted attic. The main feature of the house is a 4-bay arch-braced roof from the early 16th century. Three trusses are distinguished; the outer ones are built into the wall-tops with cusped struts above the collars forming quatrefoils. The central truss has straight principals and collar, again with struts forming quatrefoils. Wide studs, remnants of a former plank and muntin screen extending down to the first floor, are visible below the collar. Original positions are occupied by 19th-century double purlins on the backs of the principals. A 19th-century fireplace is on the south wall.
