Hay Memorial Hall, Mid Street, Cornhill

The Hay Memorial Hall, dated 1893 and designed by Duncan MacMillan, is an Arts and Crafts style hall with a mid-to-late 19th century cottage attached, gifted by William Hay. The building is oriented north-south, with the cottage positioned at a right angle to the south, serving as the warden's residence. It is a T-plan structure, two storeys high with a raised basement. The hall is constructed of coursed, stugged ashlar with polished ashlar dressings, featuring a base course, moulded cill course, and light hoodmoulds with keystones.

The north gable elevation has five bays, with a shaped gable over the three central bays and single-storey, one-bay wings flanking either side. Ashlar steps with a low balustrade lead to a broad, depressed-arch doorway centrally positioned within a heavy doorpiece of pilastered jambs, flanked by paired, half-fluted pilasters. A panelled two-leaf door is topped by a four-pane fanlight. Above the doorway, a cornice and blocking course are flanked by pedimented initial plaques. A corbelled clock tower is set into a Renaissance-style panel at the apex, featuring a blue enamelled clock face with gilded numerals within a pilastered panel, surmounted by a cornice and broken pediment with a finial flanked by obelisks. The two outer bays at ground floor level feature corniced ashlar panels. Skewputts extend into pillars with domed finials.

The east and west elevations each have three bays with further single-bay, advanced, gabled wings. A depressed arch links the three central bays, accentuated by an impost course. Each wing has a window set within a corniced panel, and a semi-circular attic window is located on the west side.

The south elevation showcases a large, depressed-arch ashlar mullioned and transomed window at the rear.

Square lead-pane glazing patterns are a feature of the timber casement windows. The roof is covered in grey slates, adorned with decorative pierced clay ridge tiles. A crowstepped gable is topped with finials. Gabled, louvred timber ventilators are present on the roof, along with a ridge ventilator. Lead guttering has been retained.

The interior of the hall is subdivided, with a main hall, a committee room, and cloakrooms to the south. The hall has match-boarded panelling to dado rail height and a raised stage to the south with an apsed recess flanked by fluted pilasters, and doors set within corniced doorcases. A panelled gallery is located on the north side, and the ceiling is ribbed wooden. Stained glass features in all windows; to the north, a roundel contains a portrait bust of William Hay, along with his initials and the date 1893. The committee room has a large stained glass window depicting flowers, swags, and abstract patterns.

The warden's cottage, dating from the mid-to-late 19th century, shares minor detailing with the hall. It is a single-storey and attic structure with five bays, situated at a right angle to the hall. It is constructed with block and sneck whinstone, and droved ashlar dressings. The south elevation has five windows at ground level, with a central gable breaking the eaves, bearing a round-arched window to the attic. A late 19th century dormer is also present in the attic. An entrance to the cottage is located at the rear, through the hall, with a further door on the north side, set within an ashlar panel, flanked by a window. Sash and case windows feature, with a three-pane upper sash and a two-pane lower sash. Ashlar coped skews, corniced stacks, decorative cans, and a finial on the west gable are also present, along with terracotta ridge tiles and a skylight.
