Stable Block to Tregrehan House

The stable block at Tregrehan House, built in 1836 for William Carlyon, is a former stable that has been converted and includes an associated mounting block. It is constructed of red local rubble with a dressed granite plinth, quoins, a mid-floor string course, and rusticated pilasters flanking the central bay, which features a flat granite arch. The roof is made of rag slate and has a central pediment with freestone dressings above a freestone arch. The building has a rectangular plan, with former stables at either end and a central former carriage bay, along with a single-storey extension at the right-hand end that includes the mounting block in front.

The exterior is two storeys high and has a 2:1:2 bay front. The ground floor features round arches over original hornless sash windows with glazing bars and spoked fanlight heads, while the first floor has 2-light casements. The central bay projects slightly forward and is topped with a triangular pediment supported by pilasters. Below the pediment is a round arch that frames a recessed tympanum containing a central casement window, all within a freestone surround, with the tympanum supported by a flat arch. The interior has not been inspected. This building is part of an important group of structures associated with Tregrehan House.
