One One One Eagle Street

Brisbane, Queensland

One One One Eagle Street forms the centrepiece of a trio of towers that mark Brisbane’s renowned Riverside Precinct. It occupies a site that comprises the loading docks and basement carpark access to the existing neighbouring towers either side. The site’s sever constraint was the lack of bearing points due to those existing encumbrances.

From this constraint evolved a structural solution which defines the tower, a web of trunks and branches developed from an algorithm called ‘growing towards the light’.  This algorithm was chosen as it was not only significantly more efficient than other solutions, but enabled a site specific architecture – rare in commercial tower design – to evolve, related to Brisbane’s most iconic Fig trees which foreground the site.

The tower comprises 56 levels, 44 of which are for offices, with the base over two levels, the upper for corporate access enabling the ground to act as internal public plaza and dining space.

The structure is designed to be read distinctively by oscillating illumination at night, and subtly by day respecting Harry Seidler’s adjoining towers.  A further aim was to create a new tower architectural typology which embodies the ‘subtropical river city’ and it has been universally recognised for this accomplishment.
