Arosfa

Arosfa is a terrace of eight workers' cottages located at Nos 7-14 Mawddwy Terrace 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 form large gables 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. These windows are topped with triangular heads made of shale voussoirs, and the upper floor windows in the central cottages are set within five large raised gabled dormers. The cottages have deep eaves, extended purlins, and ridges with shaped ends. There are stone stacks on the party walls, featuring necking strings and outsetting heads. The large gable ends display decorative timber framing in the upper half.

The internal partitions are reportedly made of slate slabs set on end, which is an innovation attributed to Buckley and his architect, James Stephens. No 8 is the northern half of the pair with No 7, forming the large gabled southern end of the terrace and also features a paned half-glazed door.
