Description
Downton House is a two-storey building with a rendered exterior, featuring a five-bay south front and two-bay 19th-century additions to the left. These additions include a large apsidal-ended rear wing and a rubble service wing set back from the front elevation. Additional ranges are set at right angles to the rear, all topped with hipped slate roofs and tall brick stacks. The entrance has an open timber porch with a flat roof, leading to a central six-panel door with a fanlight above. The windows are tall twelve-pane sashes with stone cills, while the 19th-century ranges have larger window proportions.
The interior showcases a Neo-classical decorative scheme. The hall and landing feature arches with fluted colonnettes and key-blocks, along with plaster cornice friezes adorned with triglyphs and rosettes. Doors and windows are framed with fluted architraving, and there are panelled shutters and window reveals, as well as a moulded dado rail. The marble fire-surrounds have ornamental friezes, some incorporating 18th-century cast-iron hob grates. Built-in glass-fronted cabinets and bookcases display Chippendale-style glazing patterns. The drawing room boasts an ornate plaster ceiling in the Adam style, which appears to be of a later date. The stairs run axially to the house at the rear of the hallway, featuring a plain turned newel, a ramped rounded handrail, and stick balusters.
