Description
This is a house dating to at least the 17th century, with later additions. It is a timber-frame building with a ground floor underbuilt in brick laid in Flemish bond, and a first floor clad in weatherboarding, topped by a hipped tile roof with tall brick chimneys. The building has a rectangular footprint arranged on an east-to-west axis, with three bays. It is two storeys high with an attic level.
The exterior includes a timber-frame tiled-roof porch on the front elevation, a large hipped roof that is hipped to the east and half-hipped to the west, and a pitched-roof dormer at the east end. Two tall brick chimney stacks are at the rear, along with a single-storey brick lean-to with a tile catslide roof. A late-20th century single-storey conservatory is attached to the east side. In 2022, the external windows were replaced with double-glazed hardwood units; two first-floor openings retain diamond-set square wooden mullions.
The interior reveals a large amount of exposed timber, with some replacement timbers and evidence of reused timbers. The main range has three bays, with an entrance door opening into a central hallway containing a chamfered and stopped post, exposed timber-frame walling, and a straight-flight staircase. Cross beams shared with flanking rooms support exposed ceiling joists in the ground-floor bays. The east room (kitchen) has a brick fireplace; a timber bressumer was recently removed in 2022. A large opening provides access to the late-20th century conservatory. The west room contains a substantial spine beam and joists, and a large brick inglenook fireplace with a small window and a timber bressumer. The rear lean-to has an exposed roof structure with a raking strut, rafters, and a purlin.
The first floor includes three bedrooms, where the timber framing within the external walls is visible, including tension braces, wall plates, and jowled posts. At least one further exposed spine beam and several ceiling joists are also present. A historic window opening with diamond-set square mullions overlooks the rear lean-to. A winder stair leads to an attic level subdivided into two rooms, revealing a visible timber roof structure including raked queen-post trusses, purlins, collar beams, and rafters.
