Ochil Tree House

Ochil Tree House is a house located at the end of a row on Upper High Street in Castle Cary, dating from around 1825 and likely built by carpenter William Payne. The house features finely jointed red brick in Flemish bond with Doulting stone dressings, a hipped Welsh slate roof, and brick chimney stacks. It is two storeys high and has five bays.

On the upper level, there are 16-pane sash windows, while the lower level has 4-pane sashes, all set in plain openings with rubbed brick voussoired flat heads and central keystones. In the lower bay 3, there is a 6-panel door with glazed toplights, framed by an architrave and accessed by three steps, topped with a pediment hood. Lower bay 5 features a wide elliptical arched throughway with a plain ashlar surround, inscribed on the arch and impost with "John Boyd and Co. Ltd. Estd 1867." The entrance has been divided, creating a narrow through-corridor leading to a pair of double boarded doors with panels above.

The interior has been adapted and is currently used as offices for Avalon Components Ltd, who made modifications to the rear of the house in 1979. From 1851, the house was the home of John Boyd, a horsehair weaver who established his business at Chapel Yard House in 1840. The first part of his Ansford factory was built in the grounds in 1851. The name "Ochil Tree House" comes from Boyd's birthplace in Scotland.
