State of the art mental health, drug and alcohol facility developed with sensitivity to heritage considerations

The O’Brien Centre at St Vincent’s Hospital in Darlinghurst amalgamates three previously separate services – drug and alcohol, community, and mental health – into one state of the art facility, offering an integrated service model and continuum of care for patients.

The design of the building responds to the challenges of a narrow corner block, directly adjacent to the heritage 1890’s deLacy building. By pushing the building back on the site, a new urban square is created on the street corner, and the deLacy facade, which has been hidden for many years, is given a prominent position that enhances the streetscape. The perforated bronze-anodized screen provides sun-shading on the western facade and also folds open to create a clear entrance to the building.

Internally, an open atrium creates a stairwell from level three to level seven bringing natural light and views into the core of the building. Patient facilities include a sunny common room with a large cafe/kitchen opening onto a courtyard. Patient wards and consulting rooms are planned around parallel corridors for ease of access, and finished in warm colours and materials, developing a non-institutional feel. Harbour views are captured in a two-storey glazed box on the Burton Street side of the building, which includes meeting rooms and offices.
