The Powerhouse collection surveys the history of architecture in Australia and internationally. The collection includes handmade built-to-scale models, archives, drawings and photographs ranging from iconic buildings to domestic and social housing projects.
Model making is used to accurately prototype, develop and refine an architectural design at a small scale. The Powerhouse has many fine examples in the collection that illustrate this craft, including internationally significant models of the Sydney Opera House.
The Museum also holds in its collection models of buildings, bridges and urban developments that have been made post-construction for documentation and educational purposes.
