Description

Chestnut Farmhouse is a house that dates back to the 17th century, featuring a range of three bays with an early 18th-century bay projecting to the left of the center and an 18th-century staircase projection at a right angle. The 17th-century section is timber-framed with brick infill, although part of it was rebuilt in brick during the 18th century. The 18th-century bay is constructed of chequer brick, complete with a brick plinth and band courses. The building has old tile roofs and brick chimneys, with the chimney between the right bays of the 17th-century section being made of thin brick.

The older range has one and a half storeys, while the 18th-century bay has two storeys and an attic. The windows are irregular wooden casements with single horizontal glazing bars, and the first-floor rear features gabled eaves-line dormers. The rear also includes a small blind oval window below the dormer in the left bay, a small paired leaded casement below the eaves between the left bays, and a notable 18th-century six-panelled door with an architrave frame and a wooden cornice hood to the right of the center.

The front of the 18th-century bay has a 20th-century leaded cross casement on the first floor of the gable and a similar paired casement in the attic. There is a 20th-century brick and timber porch-verandah with a hipped tile roof at the angle with the left bay, as well as a 20th-century lean-to at the southern end of the 17th-century range. Inside, the farmhouse features heavy stop-chamfered spine beams, curved braces, and a winder stair with shaped splat balusters.
