“Stephen is one of Australia’s most considered and sensitive architects with an enviable capacity to enhance, renew and invent works of the greatest quality.”
Leon van Schaik AO, Emeritus Professor of Architecture and Innovation Chair in Design Practice Research, RMIT University
Stephen Collier is an architect and urban designer whose work spans urban design, architecture, interiors, furniture, design research and independent design review. He established his practice in 2005, following professional experience in Europe and Australia, including work with internationally acclaimed Spanish architect Manuel de Solà-Morales and five years with the NSW Government’s Urban Design Advisory Service and the City of Sydney Council.
An enduring interest in the relationship between different scales of design has shaped Stephen’s education and practice. He holds a Doctor of Philosophy in Architecture from RMIT University and a Master of Large-Scale Architecture (Urbanism) from the Universitat Politècnica de Catalunya in Barcelona. During his postgraduate studies, he worked on a project for Barcelona’s Barceloneta port district that required him to consider the design of a residential interior and the form of the wider city simultaneously. This way of thinking—moving between the intimate scale of occupation and the larger structures of the urban environment—continues to inform his work.
Stephen’s early professional experience in Europe further developed this perspective. In Manuel de Solà-Morales’ office, he designed furniture while also contributing to the redesign of Antwerp’s historic docklands and riverfront; where urban form, public open space and infrastructure were considered together. The first project he worked on in the office, the La Sang urban renewal and social housing project in Alcoy, Spain, received the Premio FAD, one of Spain’s most prestigious architecture awards. He also worked on the redevelopment of the Stationsplein in Leuven, Belgium. The project transformed a chaotic, car-dominated traffic intersection into an efficient multi-level transportation hub and civic space. On his return to Australia, Stephen spent five years with the NSW Government’s Urban Design Advisory Service and the City of Sydney Council, developing an understanding of how individual buildings, urban form and the public realm relate to one another in the local Australian context of Sydney.
Stephen has worked on projects in Spain, England, Hungary, the Netherlands, Belgium, Papua New Guinea and Australia. His doctoral research examined the relationship between observation, memory, imagination and the experience of architectural space. This research continues to inform his practice, encouraging an approach that moves between close attention to the particularities of a place and a broader understanding of its cultural, spatial and social conditions.
Since 2024, Stephen has chaired the Northern Beaches Council Design and Sustainability Review Panel. He also undertakes expert witness work in the Land and Environment Court, bringing architectural and urban design expertise to the assessment of development proposals and planning disputes. He has held university teaching positions in New South Wales and Victoria.
His professional interests go beyond the making of individual spaces and buildings to the ways in which architecture shapes everyday life, contributes to the character of places and helps define the relationship between individual needs and collective interests.
