Old Hall Farmhouse, garden wall and gate piers

Old Hall Farmhouse, along with its garden wall and gate piers, dates to the 17th century and stands in Middle Mayfield. The building is constructed of ashlar with a clay tile roof featuring shaped verge overhangs, ashlar ridge stacks, and an integral end stack with grouped cylindrical shafts. The main house follows a three-room lobby entry plan and includes a dairy extension to the north, reflecting a local vernacular style.

The principal house is two storeys and an attic high, positioned to the left, with a lower two-storey dairy extension to the right. Gables are present on the left, right, and centre, each with coped verges on shaped kneelers. It has chamfered mullion windows set in rebated surrounds. Ground and first-floor windows to the left, right, and centre (except for a casement on the first floor right) feature four transomed lights. Other windows are two-light chamfered mullioned. Continuous hood moulds cover the ground and first floor windows while the attic windows have long, straight hood moulds. A gabled porch is situated to the right of centre, with a four-centred arch leading to a 20th-century glazed door within a square-headed doorway, also with a hood mould. The dairy extension incorporates a three-light chamfered mullioned window on the first floor.

Inside, the house reveals an exposed 17th-century close-studded timber-framed partition between the central and south rooms. An inglenook fireplace is found in the north room, and the south room displays a 17th-century decorative plastered ceiling. A set of 17th-century panelled doors, originally from the attic, have been relocated downstairs. The roof structure features 17th-century trusses with vertical studs between the collar and beam, double trenched purlins, and wind braces. A coped ashlar wall and square section gate piers topped with concave-sided caps enclose a small front garden, contributing significantly to the setting of the farmhouse.
