Ty-Hyll (The Ugly House)

Ty-Hyll, also known as The Ugly House, is a single-storey cottage built in a pseudo-vernacular style. The cottage is constructed from large, undressed boulders, some weighing up to 3 tonnes, with smaller stones arranged in a dry-galetted manner and packed with moss. It features a recently renewed small-slate roof with deep eaves supported by crude boulder corbels.

On the right gable, there is a tapering semi-circular chimney projection that ends in a squat conical stack, while a tall, randomly-built boulder chimney is located at the rear. The entrance is near the center and has a modern boarded door set within a stopped-chamfered frame. To the left of the entrance are wooden mullioned windows, which have been renewed, featuring 2 lights, and to the right, there are 3 lights, both with leaded glass. Additional leaded windows are found on the left gable end, along with a primitive triangular-headed window in the gable apex, which contains a late 19th-century 4-pane sash. The verges are deep and supported by large slatestone slabs.

At the rear, there is a narrow 2-panel door flanked by 8-pane casement windows that serve the attic floor, which is contained within large gabled dormers. Inside, the cottage has a modern slate-flagged floor and a 3-bay modern framed ceiling made of oak, with stopped-chamfered joists. There is an end fireplace on the right with a roughly-dressed slatestone lintel and jambs, the latter featuring crude abaci, and a semi-circular slate hearthstone for the open fireplace. A modern stair and partitioning lead to the attic floor.
