Description
Y Bwthyn is a double-fronted, one-and-a-half-storey house. It was originally built with a stone structure, now covered with a pebble-dashed finish, and has a slate roof with a chimney stack on the right side. The windows have been replaced and are set within smooth-rendered surrounds, which also frame raked half dormers in the roof. A lean-to porch with a half-glazed door sits at the central entrance. To the left, a two-window extension projects forward under a slate roof, featuring a left-end chimney stack and a doorway in the gable end. The rear of this extension is splayed, reflecting the location of the house backing directly onto the road. A further half dormer has been added to the rear of the main house. The building was not inspected.
