No 23 (Rockhill House), With Walls Enclosing Garden To North East

No 23, also known as Rockhill House, is a house built in the early 18th century and modified in the early 19th century. It is constructed from local stone rubble, which is rendered and colourwashed on the front elevation. The house features a hipped Welsh slate roof with a large eaves overhang and brick chimney stacks. It stands three storeys high and has three bays. The ground floor has large 12-pane sash windows, while the first floor has 16-pane sash windows, and the second floor has casement windows, all set in plain openings. The central entrance consists of a 6-panel door with a fanlight, located in a semi-circular arched recess.

Although the interior has not been seen, the boundary walls surrounding the garden are made of local stone with brick backing and ashlar copings. These walls are approximately 1.25 metres high on the south side, where they sweep up to the house, and are level on the north side. The east boundary averages 1 metre high and features plain railings about 600 millimetres high above. There are square ashlar gate piers with pyramidal tops and a 20th-century metal gate.

The house was built for Bartholomew Day between 1725 and 1742, with modifications made around 1830 to 1840, as noted in G. Sweetman's "History of Wincanton," published around 1904.
