Walled Garden, Westerton House

Westerton House is an early 19th-century classical house with alterations and additions made around 1910. It features two storeys and an attic, with a symmetrical design comprising five bays on the right and a later sixth bay on the outer left. The exterior is finished in painted stucco and includes a base course, blocking course, and paired pilasters flanking the original bays.

The south elevation, or main front, has a pedimented centerpiece that highlights the five-bay block. It includes a modest tripartite doorpiece with a two-leaf studded Gothick door, a blind round-arched fanlight, and narrow lights. Above the door is a broad window flanked by blind oculi and topped with a triangular pediment that has a blind oculus at the center, capped by urns. The two symmetrical bays on either side are terminated by paired pilasters, and there are later canted dormers symmetrically placed. The broad sixth bay on the outer left has windows on both the ground and first floors. An L-plan link connects to a service block on the outer right, which was formerly a gabled rectangular block serving as a chapel.

The west side elevation has two bays, featuring an advanced full-height projecting tripartite window, with bipartite windows symmetrically placed to the outer left, and canted dormers.

The north rear elevation includes a piend-roofed blank block on the outer right, with recessed bays at the center and an advanced single-storey, two-bay block on the outer left.

The windows are plate glass timber sash and case, and the roof is covered with grey slate and lead flashings, with coped apex and ridge stacks.

The service wing is a two-storey gabled block aligned north-south, with the rear portion possibly having had ecclesiastical use, also finished in stucco. The north elevation features a pointed arch window with a leaded light at the center, flanked by blind cruciform arrowslits at the ground level, and three blind quatrefoils symmetrically arranged in the gable. The south elevation has a blank gable, while the east elevation consists of three bays, with a window at ground level to the right, a bipartite window above with a gable breaking the eaves, a broad blank bay at the center, and a bipartite window at ground level with a dormer-headed bipartite window above on the left.
