Description

Westbury House is a former farmhouse that has been converted into flats, specifically Flats 1, 2, 3, and 4. It dates from the 15th or early 16th century and was originally an open hall house with two storeys. A south crosswing was added later in the 16th century, likely between 1564 and 1569 by Robert Ivory. The building features a jettied porch and a taller north crosswing, which may date from the same period or the early 17th century. There are also 19th and 20th-century gabled additions at the rear.

The structure is timber-framed with a stuccoed brick sill and roughcast exterior. The ground floor of the south wing at the front is plastered. At the south end, there is a roughcast, single-storey, L-shaped brick outbuilding. The house has steep old red tile roofs and is H-shaped, facing east and set at the back of a farmyard. It has two gabled crosswings, a gabled jettied porch with a pointed archway, and a two-storey canted bay window to the right of the porch.

A large internal chimney is located at the junction of the centre and north wing, featuring a semi-circular attached shaft and a broad stepped face above the roof with a renewed red brick corbelled cap. There are internal gable chimneys at the rear gable of each wing and a narrow projecting stair tower at the rear angle of the centre with the north wing. The front of the house has generally three-light flush 19th-century lattice casement windows, with two-light windows in the attic at the top of the gable of the north wing. A gabled dormer on the north roofslope also provides light to the attic floor.

Inside, the hall features an elaborately moulded cross-beam that supports the inserted floor, with a hollow moulded bracket supported by a chamfered post on the rear wall. The older south service wing consists of two bays with jowled posts, convex-curved tension braces set inside the wall studs, and a clasped-purlin roof with one purlin in each slope carried on collar-and-queen-struts. There are mortices under the tie-beam for a cross-partition into two rooms on the first floor and presumably for service rooms on the ground floor, along with an edge-halved scarf in the wallplate.
