Description
Nos. 10 and 12 Lon Isa are a pair of semi-detached houses dating from the 19th century. They are two storeys tall and feature roughcast render with exposed grey stone on the ground floor front. Each house has a slate roof with a chimney. The front elevation showcases a large pair of gables with half-hipped roofs. On the first floor, there are four windows: each house has a 2-light casement window towards the centre and a narrow casement window at the end. On the ground floor, each house features a 3-light casement window towards the centre, along with a doorway. In the narrow recessed outer bays, which are located beyond the gables, there is a small square window on the ground floor. The glazing has been replaced.
