Description

Moor Cottage is a house dating from the late 15th century or early 16th century, originally built as a cruck-framed open hall house. It features a hipped west rear wing, with the hall floor, front gable, and chimney added in the late 17th century. The windows were altered and brick infill was added in the early 18th century, and there are small lean-to extensions at the rear from the 1960s. The timber frame sits on a red brick sill with red brick infill, and the roofs are steeply pitched with old red tiles.

This 1.5-storey T-plan house faces east and has a three-window front with flush casement windows. To the left of the right-hand window is a panelled door that indicates the former position of a cross-passage. A large gable to the left of the door features a jettied top over a four-light leaded casement window that lights the chamber above the hall, which has a similar four-light window below. There is a two-light window in the south end parlour, which has a later external gable chimney.

Inside, a large cruck truss is exposed in the north gable end, which was formerly half-hipped, as shown in a drawing by Buckler from 1838. Each floor has three-light casements. The interior is of considerable interest as it retains much of its original form and details. It originally had three cruck-framed bays that were open to the roof, except for the north bay, which features a cross-passage and service rooms divided axially. The original floor consists of flat joists supported by an axial beam, and the staircase is likely located on the west wall. There is a closed truss between the passage and hall, open below the cross-beam. Peg-holes for a bench and bench-end are found at the south (upper) end of the hall, along with evidence of a large casement window that was originally on the east side. The cruck blades are unusual, with four pairs terminating just above the collar beam, classified as Type W in N Alcock's 1981 catalogue on cruck construction. The use of a side-chimney when the hall was floored in the 17th century is also notable.
