Castletown

Castletown is a house built in 1811 by Peter Nicholson and William Reid for Robert Mounsey of Carlisle, with a rear facade dated 1831. It is constructed from calciferous sandstone ashlar and features a chamfered plinth, a moulded cornice, a parapet, and angle pilaster strips. The roof is made of green slate with lead hips and stone chimney stacks. The building has two storeys and five bays, with flanking pedimented wings that are two storeys and two bays each, as well as extensions to the right that include a two-storey single bay and a single-storey three bay section.

The garden front boasts a stepped tetrastyle portico with squared columns and incised decoration, a design commonly used by Paul Nixon, a stonemason from Carlisle. It also features a moulded cornice and a cast-iron balcony. The entrance includes a glazed door with a fanlight and sidelights, along with a large overall round-headed patterned fanlight. The large casement windows on the ground floor have external louvred shutters, while the upper floor features sash windows with glazing bars.

The rear entrance is marked by two Doric columns in antis. Inside, the house has moulded plaster ceilings, panelled shutters for the windows, and panelled doors. The hall is highlighted by Doric columns and a semicircular cantilever staircase, while the dining room features Ionic columns with an entablature.
