1 William Street, Brisbane

1 William Street is a modern office building in Brisbane that rises over 46 floors above ground and extends 3 levels below. The structure serves as a major government administrative center housing multiple state agencies.

The site began as a manufacturing and shipping area in the mid-1800s, later became a government car park, and was redeveloped starting in 2013. The transformation reflects the city center's shift from industrial uses to modern administrative functions.

Each floor carries references to Queensland throughout its design, with different levels showcasing local elements like barramundi fish, fig trees, and sea fans. These touches tell stories about the region and its natural character.

The building houses approximately 5,000 government employees from multiple state departments and offers extensive internal transportation. Visitors should know this is an administrative building, so certain areas may not be open to the public.

The building was designed with deliberate energy efficiency measures built into its entire structure to minimize consumption. Green features are woven throughout, making it one of Brisbane's more environmentally conscious government buildings.
