The Round House Including Garden Boundary Wall Adjoining South

The Round House, a toll house built in the early 19th century, is constructed of painted stone rubble and was formerly slate hung. It features a slurried scantle slate hipped roof topped with a stone ball finial. The building has a square, one-room plan with a direct entry through a doorway located in a splayed corner, and an unheated room at the back in a single-storey integral outshut.

The exterior is two storeys high, with a plank door in the splayed corner and a window above it, along with similar windows on both floors of the returns. The windows are 20th-century two-light casements, and there is a small single-light window on the ground floor to the right. A small stair window is located on the east side, and there is a single-storey outshut with a lean-to roof at the rear. The south side includes a low curved painted stone rubble boundary wall.

Inside, there are plank doors, and the fireplace has been blocked by a late 20th-century chimneypiece. The Round House was built by the Tavistock Turnpike Trust, which was formed in 1762.
