Mount Alyn Lodge (including gate piers at drive entrance)

Mount Alyn Lodge comprises three blocks: a gatekeeper's lodge of four bays to the west, a central carriage house, and accommodation of three bays to the east. The building is constructed of brick and features dentilated eaves under a pitched slate roof. The western block is two storeys high, while the eastern block is three storeys high.

The western block is rendered and retains twelve-pane sash windows on its northern elevation, with an original sideways-sliding sash window in the cottage ornée portion. A late 19th-century wooden porch with carved and pierced barge boards is present at ground floor. The western elevation is three-sided, designed to provide views of the drive towards Mount Alyn. The eastern block has a two-storey canted bay projection topped with Victorian decorative ironwork and a two-storey projecting gable end from the central carriage house section. It features four-pane sash windows to the northern elevation and a separately articulated stair turret to the south, capped by a pyramidal roof with a lead ball finial. The north-facing side of the central section has no windows, while the south-facing side has a segmental arched carriage opening and open windows. An attached wall extends eastwards from the arch, connecting to the former wash-house and toilet.

The cottage ornée section has been converted to a garage at ground floor level, likely in the early 20th century, and it has a corrugated iron roof projecting from floor level. Three blocked windows are located on the first floor, positioned under an open triangular pediment with dentilated details. Some original render remains on this section.

To the north of the building, two Gothic Revival gate posts of carved stone, with decorative ironwork to linking stone walls, flank the drive. Each gate post has a two-centered drip stone over a trefoil inset panel. The carved foliage to the cusps and drip stone are left unfinished on the east side.

In the western block, no original fixtures and fittings were observed, although exposed floor joists are boarded over. Access to the eastern block was not possible during the 1996 re-survey.
