Description

Corneybury is a manor house that likely originated in the late 16th century, with the northern front remodeled in the early 17th century and the wings updated in 1681 for Charles Crouch, as indicated by the initials '1681 CC' on the rainwater heads. The western front was altered in the 18th century, and the house underwent renovations for William Butt in the early 19th century, with wallpaper documented for the drawing room from 1826-1829.

The building is constructed of red brick from different periods and features steep old red tile roofs. It is an irregularly shaped house oriented east-west, with an E-shaped symmetrical formal northern front that includes a projecting porch and flanking wings. The house has two storeys and attics, with a lower section at the southeast. The northern front showcases gables on the projecting wings and a central feature with moulded brick gable parapets, oval attic windows set in square frames, and three-light mullioned and transomed windows, all with leaded glazing and iron opening lights.

A late 17th-century central Ionic porch with a pediment and a six-panel door is present, along with a restored pedimented brick aedicule above that features a statue of Juno. The front of the northwest gabled wing has been re-erected to face a short extension to that wing, likely from 1681, which includes a large chimney backing onto the window openings. The parapeted and gabled contemporary western end was altered in the 18th century with the addition of a two-storey segmental brick bay window that has segmental arched windows, and sash windows were inserted, with deeper ones on the ground floor. The side windows on the ground floor were later modified to triple sashes in the early 19th century. The southern front has three plus one sash windows on each floor with six-over-six panes, and round-headed windows in the lower southeast part, which likely served as a former conservatory.
