A hidden gem reborn at the centre of the city, OneNinety allowed us to reimagine the office lobby experience. Representing a paradigm shift from the archetypal corporate lobby, we utilised a crafted, contextual approach that responds to the changing work culture of forward-looking tenants. We imagined a boutique club-like experience and an atmosphere, design quality, and level of service commensurate with a boutique hotel. 
 
Shared social, collaborative and focussed zones blur the lines between the workplace and ‘third’ place. 
 
OneNinety’s defining feature is the ‘Living Laneway’ – a string of curated experiences extending from the St Georges Terrace point of entry, through the activated lobby to a sheltered, leafy urban courtyard and through to Hay Street along the upgraded service lane. This spatial journey elevates everyday movement into an atmospheric progression, drawing in light, greenery, and people.

Anchoring the ground plane is a bold, unifying datum – a dark banded material expression that wraps from the exterior to the mezzanine level, tying architecture, program and circulation into a cohesive visual language. Full-height glazing replaces outdated facades, opening formerly underutilised edges and reconnecting the building to its urban context. Picture windows along the western façade frame views to the Cloisters precinct and a mature heritage fig tree, reinforcing connections to history and place.

Copia, a central café and wine bar, enlivens and offers a warm and vibrant heart to the building. Much more than a hospitality venue, it fosters informal interaction and community connection, blurring the distinction between public and private space. Our inclusive programming embraces the wider community and introduces a welcoming permeability that is rare in CBD commercial developments.
