Hillside, Former Sunnyside Hospital, Booth House

Hillside, originally the nurses' home for Sunnyside Hospital and later known as Booth House, is a building designed by John Alexander Ogg Allan between 1931 and 1935. It is an Arts and Crafts style building, now used as offices (as of 2012). The building has a long, near-symmetrical design, with two main storeys and an attic, and three-storey gabled end wings, forming an H-plan. It is built of painted concrete harl with contrasting ashlar stone margins. The building has a base course, deep eaves to both the upper and lower slopes of the mansard roof, and dormers abutting the upper eaves. Window openings are generally rectangular, with some round-arched openings on the south side. Some windows are bi-partite (two-part) or tripartite (three-part). A flat-roofed extension is located to the east.

The south elevation is symmetrical, with a central, two-and-a-half storey, sixteen-bay section flanked by projecting, three-storey, gabled end bays. A central, single-storey, five-bay, flat-roofed porch projects forward, featuring large, key-stoned, round-arched window openings and stone piers and railings which form a balcony to the first floor. The porch has moulded architraves. The end bays have canted bay windows with five lights on the ground floor, and four-light windows on the second and third storeys, with slit window openings in the gables.

The north (entrance) elevation is also symmetrical, with a central, two-and-a-half storey bay featuring a wide, key-stoned, moulded, round-arched entrance opening. The entrance has recessed, multi-pane, glazed, two-leaf doors with a glazed fanlight and side panels, flanked by stone panels with carriage lights. Above the entrance, there are tripartite window openings, and a single attic dormer.

The west elevation is asymmetrical and three storeys high, with nine bays. An off-centre gabled bay incorporates a canted bay window with four lights on the ground floor, and prominent wallhead stacks are present.

The building has predominantly multi-pane metal casement windows with top-opening hoppers. A mansard roof covers the central section, and there are ridge and wallhead stacks, as well as cast-iron rainwater goods. Gables have raised skews.

The interior, observed in 2012, retains a fine decorative scheme and its original layout is largely intact. A full-height, panelled lobby and entrance hall are present, alongside a multi-pane glazed screen with central swing doors. There are engaged polygonal-plan timber columns, and a dog-leg staircase with moulded timber banisters and curved newels. The ground floor corridor features timber dado panelling, part-glazed doors with fanlights and sidelights. Upper storeys have boarded timber doors with opaque glazing, and residential rooms contain integral pointed-arched wardrobes.
