10 Mawddwy Terrace

10 Mawddwy Terrace is part of a terrace of eight workers' cottages located in Minllyn, Dinas Mawddwy. Built in the mountain-Gothic style, the cottages are constructed with selected local slate laid on bed and feature slate roofs. The design includes two bilaterally symmetrical cottages that create a large gable at each end, which are set slightly forward to dominate the central cottages. Each cottage has a 4-paned half-glazed door with a plain overlight, and 4-paned horned sash windows on both floors, all topped with triangular heads made of shale voussoirs. The upper floor windows in the central cottages are set within five large raised gabled dormers. The cottages have deep eaves supported by extended purlins and ridges with shaped ends. Stone stacks are located on the party walls, featuring necking strings and outsetting heads. The large gable ends display decorative timber framing in the upper half. Internally, the partitions are reportedly made of slate slabs set on end, which is an innovation attributed to Buckley and his architect, James Stephens. This terrace is part of the group of cottages numbered 7 to 14 Mawddwy Terrace.
