Description

Trehane Coach House is a house that was originally the coach house for Trehane House, which is now in ruins after a fire in 1946. Built in the 18th century, it features brick laid in Flemish bond on a stone base, with a hipped scantle roof and brick chimneys. After the fire in the main house, the building was raised in height and converted. It has a rectangular plan and is now two storeys tall, whereas it was originally a single storey. The facade includes three windows and a central door in a reduced opening, with ground floor openings spanned by shallow brick arches. The windows are 12-paned sashes with sidelights. A notable feature is a lead rainwater head and downpipe from the old house, dated 1703, which bears the initials W.I.C. for Williams Impaling Courtenay. This rainwater head is finely crafted, featuring a semi-circular sump, a shield with lions above, and a moulded cornice. The interior was remodelled after 1946.
