Rotunda Lodge, 16 Polmuir Road, Ferryhill, Aberdeen

Rotunda Lodge is a mid-19th century lodge with a basement and attic, situated at 16 Polmuir Road, Ferryhill, Aberdeen. The building is constructed of granite rubble with stugged long and short dressings. A base course, chamfered reveals, long and short quoins are present.

The east (principal) elevation is asymmetrical. A gableted doorway is centrally positioned on the ground floor, accessed by six stone steps leading to a modern glazed panelled door with a letterbox fanlight; the right return is blank. There are windows to the ground and first floors within a recessed bay to the right, with a modern gableted dormer to the attic floor, which is flanked to the left by a skylight. A gabled bay projects to the left, featuring a canted three-light window on the ground floor, a narrow round-arched window in the gablehead above, and a spherical stone finial to the apex. Another modern dormer is situated to the re-entrant right of the attic.

The north elevation is gabled and blank, with a modern car-port on the ground floor. The west elevation is asymmetrical and largely obscured by a mansard-roofed wing. A panelled door with a letterbox fanlight is centrally positioned on the basement floor, while a decorative two-storey timber conservatory adjoins the outer right angle, obscuring a recessed flanking bay to the right. An attic gable above the conservatory has a window to the centre and a stone finial. A doorway is located on the left return of the conservatory, while two windows are present on the basement of the left return of the wing. Decorative stained glass windows are above, flanked by a window to the left; a window is also present on the basement floor of the flanking bay to the left.

The south elevation is near-symmetrical, with a regular fenestration pattern on the basement and first floors and a gableted modern bipartite dormer on the attic floor to the left.

The majority of windows are timber sash and case. The roof is covered with graded grey slate and lead ridges. Ridge and gablehead stacks are present, with triple offset coped brick flues and circular cans. Coped stone skews feature blocked skewputts. Cast-iron rainwater goods are incorporated.

The interior showcases fine classical and Scots Renaissance plasterwork and friezes in the principal rooms and hall, with surviving cornices, skirting boards, and fireplaces.

Boundary walls of coursed, coped Aberdeen bond rubble granite are located to the east, with rectangular-plan gatepiers featuring pyramidal caps (spherical finials missing). Brick coped rubble walls extend to the remainder of the property.
