Description
Bron Turnor Mawr is a substantial early 19th-century house that was formerly a rectory. It features a symmetrical design with two stories and a four-window range, including a central advanced bay with two windows. The building is constructed from roughly coursed mortared rubble masonry, using large stones for the quoins and lintels. It has a hipped slate roof with advanced eaves and verges, broad end stacks that have dripstones and capping, and flat coping over a hood. The main façade faces the road and the river valley to the south, showcasing slightly recessed 12-paned hornless sash windows. The interior was not inspected during the survey conducted in June and July 2003.
