Description

Tregarth is a 1-storey building featuring 3-bay pebbledash elevations on both streets, with gables above the upper windows. It has a tall slate roof and a very tall chimney stack on the right side. The Bridge Street front has two gables with small pane casement windows and two shop fronts on the left, which include pilasters and tiled stallrisers. The right shop front features a dentil cornice and a blocked-up doorway. There are modern windows and a recessed door to Henblas on the right side.

The corner of the building is partly splayed. On the Chapel Street front, there are three gables; the outer gables have similar windows to those on the Bridge Street front, while the central gable is smaller. The roof is undulating slate with a central chimney stack. The left side of Tregarth has a 16-pane sash window on the ground floor, a 4-pane window with a cornice in the center, and a late Georgian shop front on the right, flanked by pilasters. The broad gable end facing southwest features casement windows, a swept roof dormer at the rear, and a half-glazed door under a lean-to hood supported by reeded iron columns.

Inside Tregarth, there are deeply chamfered and stopped cross beams and joists, along with a timber lintel over a modernized inglenook. Some doors have roughly fielded panels.
