Old Farmhouse at Ty-brith

The Old Farmhouse at Ty-brith is a building featuring rubble stonework and a slate roof, with corrugated iron at the rear and red clay ridge tiles. The upper east bay has a corrugated asbestos roof. There are two doorways on the south side and one on the north side, while the added building includes a boarded door and a window opening.

Inside, the main open hall truss is made from substantial raised crucks that are morticed for a deep cambered collar. Knee braces with ovolo mouldings on the lower edges extend to the centre of the collar. A notable king-post above has sunk ovolo mouldings on each face and is shouldered, shaped to accommodate four mortices for braces to the upper part of the blades and to the ridge, although these two are now missing. The blades are tenoned at the top into the king post, which is trenched to support a square set ridge piece. There is significant evidence of smoke blackening. The total span of the hall is 4.75 meters, and its length is 7.65 meters.

The closed truss that forms the partition to the lower bay has slightly curved and tapered blades set into the walls, along with a cambered collar and king post. A shoulder is present only on the hall side, though it is unclear if it is applied. Two long curved braces from the blades descend to a raised sill, which also features a vertical stud to the collar. Small plates, pegged to the blades, are trenched on top for the wall plate on the stone walls. A subsidiary timber on top of the blades supports the lower tier of purlins, which are held in place by a substantial rectangular peg driven into the top face of the blade. The purlins appear to be out of their original position, although they are drilled for pegged rafters. The ridge over the lower bay is set diagonally, and the slates have been torched.
