Colville Lodge, 43 High Street, Ayton

Colville Lodge, located at 43 High Street in Ayton, was built in 1851 and has undergone later additions and alterations. This symmetrical, two-storey, three-bay house features gabled roofs and Tudor gothic details. It has a full-height gabled wing that projects at the rear, creating an L-shaped plan, and a later single-storey gabled addition on the southeast side.

The front of the house is constructed from coursed and tooled cream sandstone, with sandstone ashlar dressings. The sides and rear are built from harl-pointed rubble, while the single-storey addition is finished with painted harl. Notable architectural features include a raised base course, raised quoins, and droved long and short surrounds to the chamfered openings. The windows have painted mullions and battered cills.

On the southwest elevation, which serves as the entrance, there is a timber panelled door at the centre of the ground floor, flanked by narrow sidelights and topped with a plate glass fanlight. A full-width Tudor-arched porch with columnar supports and a piended roof enhances the entrance. Above, there is a corniced, square-headed, bipartite window aligned with the first floor, featuring a dated carving above it. The gablehead is topped with a corniced stack. The ground floor has corniced, square-headed, bipartite windows in the bays flanking the entrance, while pointed-arched, Y-traceried windows break the eaves above, each adorned with coats-of-arms in the gableheads. A bipartite window is centred in the single-storey addition to the outer right.

The northwest side elevation is a blind elevation to the gabled block on the right, while a full-height, two-bay wing is recessed to the outer left. The northeast rear elevation features a gabled projection offset to the left of centre, with a full-height block recessed to the right that has a single window at the first floor, also offset to the left. The southeast side elevation was not seen in 1998.

The house predominantly features 8-pane glazing in timber sash and case windows at the front, with some secondary glazing and 12-pane glazing in the rear windows. The roof is covered with grey slate, with stone-coped skews and moulded skewputts. There are brick-built apex stacks on the northwest and southeast sides, a corniced apex stack at the front, and various circular and octagonal chimney cans. The property has cast-iron rainwater goods.

The boundary wall surrounding the site at the front is made of heavily-pointed rubble, and there are square-plan weathered sandstone gatepiers flanking both vehicular and pedestrian entrances, each topped with pyramidal caps.
