She has worked for a diverse range of both public and private clients including: Lendlease, City of Sydney, Artbank (Australian Federal Government Initiative), Firstdraft Gallery, NSW Department of Planning and the Government Architects Office.

Aileen Sage is the alter ego she created with Amelia Holliday in 2013 as a pseudonym for their partnership that includes practice, research and education. Recognised for their narrative-based approach and unexpected multidisciplinary collaborations, Aileen Sage is interested in how art and design can encourage meaningful connections and interaction between people of varied generations, backgrounds and cultures.

In 2016, Aileen Sage produced the project 'The Pool: Architecture, Culture and Identity in Australia' as co-creative directors for the Australian Exhibition at the Venice Architecture Biennale. The project combined multiple creative industries, academics, technical and engineering experts and nationally significant cultural commentators. The publication produced for the exhibition, won the Adrian Ashton Prize for Architectural Writing and Criticism and has been shortlisted for The Cornish Family Prize for Art and Design Publishing. The radio stories produced for the exhibition have been featured on national public radio and are held as a resource on the ABC Radio National website.

Isabelle is actively involved in the architectural and creative arts community and is regularly engaged in speaking, teaching and critique at all three schools of architecture in Sydney as well as the University of Canberra and the Design degree at the National Institute of Dramatic Arts (NIDA). She has also spoken about working across art and architecture at the Art Gallery of NSW, Newcastle Region Art Gallery and the Sherman Contemporary Art Foundation.
