Description

Picton House is a two-storey house built with painted roughcast and topped with a slate roof that overhangs at the gables. The building features a three-window range of large sash windows, with 12 panes in the upper windows and 16 panes in the lower ones, all set on slate sills. The central entrance includes an arched door with a radiating-bar fanlight, which is positioned behind a later glazed outer door. The wall face also has a fanlight.

At the base, there is a stucco plinth with broad raised angle piers on either side. The ground floor has a blank Gothic panel, while the first floor features an inset cross. The right end wall contains a small 6-pane sash window with marginal glazing, positioned above an added gabled porch that features angle piers, an arch, and a thin impost band. There are small fixed windows on either side of the porch. Inside, there is an arched door with a radiating-bar fanlight above a heavy 6-panel door that has iron studs.

The left end of the house is stuccoed on the right side but is slate-hung on the rest, and it has an added late 19th-century square bay window with a hipped slate roof. At the rear, there is a long two-storey lower northwest wing. The first bay of this wing is slate-hung and features a long stair-light above a low basement door. There is a stepped joint leading to the rest of the wing, which is stuccoed and altered, with brick ridge and end stacks. The windows include a long 20th-century metal window on the ground floor, followed by a 4-pane sash on each floor, and the last bay steps forward with a similar sash on each floor.

Additionally, there is an outshut at the rear of the original house and an added single-storey northeast rear wing. The interior is not available for inspection.
