Headlam Hall

Country house with a 17th-century core, potentially incorporating older stonework, largely encased by an L-shaped entrance block dating to the mid-18th century and an early 20th-century north wing. The 17th- and 18th-century ranges are constructed of dressed sandstone, whilst the north wing is of sandstone ashlar, all set beneath sandstone flag roofs.

The three-storey entrance front comprises three linked sections. The right section is a mid-18th-century block of five bays (with a narrower five-bay return), exhibiting a chamfered plinth, raised and chamfered quoins, a richly-detailed, rusticated surround to the central, glazed double doors, and 12-pane sashes to the ground and first floors, and 16-pane sashes to the second floor, all within raised surrounds. The recessed middle section, also mid-18th-century, is two storeys with a third storey added in the early 20th century, featuring Venetian windows to the ground and first floors and a tripartite window to the second floor. A projecting, three-bay north wing to the left has quoins and 12-pane sashes in raised surrounds; its left return displays two corniced lateral stacks. The steeply-pitched and slightly-swept hipped roof has a flat top over the north wing, with three massive, corniced ridge stacks.

The three-storey, nine-bay rear elevation, with mainly renewed mullioned windows, retains 17th-century character. The E-shaped centre block contains some original mullions and is flanked by recessed single bays, with a projecting mid-18th-century bay to the left and a far-projecting north wing to the right. Four extruded bays of two and three storeys sit between the projecting rear bays. The central block features 3- and 4-light mullioned windows, with a central door under individual hoodmoulds to the ground floor; the first and second floors have mainly 4-light mullioned-and-transomed windows. The roof is hipped over each of the five projecting bays.

The interior has been altered in the early 20th century but retains a mid-18th-century panelled entrance hall with a pair of Tuscan columns. An upstairs room is said to contain Jacobean panelling and a late 17th-century chimney piece with strapwork decoration.

A detached stable range to the north and a stable block to the east are not of special interest.
