A hidden gem reborn within Perth’s CBD, OneNinety evokes a boutique club-like atmosphere with the design quality, character and level of service commensurate with a boutique hotel.

Representing a paradigm shift away from the archetypal corporate lobby experience, it utilises a crafted, contextual approach that responds to the changing work culture of forward-looking tenants bringing them greater flexibility and access to services, amenities and spaces beyond their own tenancy. Shared social, collaborative and focussed zones blur the lines between the workplace and ‘third’ place.

Its defining asset 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, verdant urban courtyard beyond and extending 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 Full-height glazing replaces outdated facades, opening formerly underutilised edges and reconnecting the building to its urban context.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 visual connectivity and place.
