What Aileen Sage does
Aileen Sage is a Sydney-based architecture and design practice founded in 2013 by directors Isabelle Toland and Amelia Holliday. The firm provides integrated services across architecture, landscape architecture, heritage conservation, and public art strategy, delivering projects from inception through completion. Its client base includes government and institutional clients (City of Sydney, NSW National Parks and Wildlife Service, Museums of History NSW, Western Parklands City Authority, Bundanon Art Museum), property developers (Meriton, Scape, Toohey Miller, Mirvac/John Holland JV), cultural institutions, and private residential clients. Project types span large-scale residential towers, adaptive reuse of heritage buildings, public amenities, museums and exhibitions, and site-specific art installations.
The practice is distinguished by a narrative-led, context-responsive design methodology that embeds Indigenous knowledge through its "Connecting with Country" framework, sustained via long-standing collaborations with Indigenous design consultancies including Djinjama, Yerrabingin, Bangawarra, Murawin, and Tyrell Studio. Delivery is supported by BIM-led documentation and integrated quality assurance systems. The firm has won multiple City of Sydney Design Excellence Competitions, and its Bobbin Head amenity design was adopted as the statewide standard for NSW National Parks. International recognition includes the 2016 Venice Architecture Biennale commission for The Pool and publication in The New York Times, Dezeen, and Architecture Australia.
Aileen Sage operates as a privately held design collective with no external institutional investment. Revenue is generated through project-based professional services fees negotiated on a per-project basis, typically delivered under multi-year contracts. Work is sourced through design competitions, direct government and developer commissions, and referrals. The firm has grown organically from a founding partnership of two to a team of 10+ designers, architects, and researchers, with founding directors maintaining close personal involvement across all projects.

- Tonkin Zulaikha Greer: Sydney-based mid-sized architecture practice with a comparable integrated focus on heritage adaptive reuse, cultural and public projects, and a similarly strong record of design competition wins and awards. Directly comparable in scale, project types, and client base.
