Blight Rayner has designed a 29-storey campus style office tower that will sit high above a “gorge-like” open ground plane on Brisbane CBD’s northern edge.
The 200 Turbot Street proposal, submitted to Brisbane council for planning assessment, will sit between Wickham and King Edward parks, across from a four-storey 1940s Neo Georgian heritage building, the former Brisbane Dental Hospital and College.
The “eroded” tower base has been designed to unlock the surrounding steep and rocky landscape, while a glazed foyer pavilion echoes the scale of the adjacent heritage building and defines the southern edge of the site.
Negotiating a 15-metre topography shift, the 20 metre-high space at ground level will provide for improved pedestrian movement and lines of sight between Wickham Park and Turbot Street.

“Centrally, a series of landscaped terraces, stair and escalators create a landscaped amphitheatre,” Blight Rayner states.
Two railway corridors that sit just below the surface of the site present as another key constraint, limiting foundation and load point options. Blight Rayner explains in planning documents how the tower design negotiates this problem.
“The tower is shaped, folded organically with a migrating structure which is designed to minimise load points,” the architects note. “The structure is designed to migrate to load points which straddle the two rail tunnels.”
The site is owned by the Queensland government, but developer Mirvac is behind the development proposal under an agreement which allows the comany to hold off on purchasing the site until it can find an anchor tenant.
The development application was submitted to council on 4 August.
