The design solution for the site has resulted in a simple geometric form generated from a pure half ellipse which, by its very shape, simultaneously allows a widening towards the northern end of the floor plate to capture key views and light and draw them into the floor plate and contraction towards the southern end where the core tucks neatly and efficiently into the curvature of the ellipse.
This results in a highly efficient floor plate set in a modern side core configuration, which provides tenants with complete flexibility in the use of space. A side core configuration provides the following benefits over a traditional central core building:
- higher degree of flexibility in fitout
- improved interaction of staff being all located centrally and not staggered nor divided by a central core
- improved sense of equality amongst staff with an even distribution in the access to shared natural light and views
- opportunities for internal tenancy communication stairs within the floor plate
There are essentially two facades:
- The East, West and South facades are one continuous curved skin, which is discreetly treated with solar controlled frit patterns which subtly change and merge in response to the activities within.
- The North facade responds to the northerly sun angles with external horizontal louvers to provide passive shading. The main building entry is recessed to form a generous plaza on the northern side, prompting activation of the ground floor retail spaces, including a café and possibly a child care centre. The commercial lobby space is defined by an elegant curved wall leading towards the expressed lift core within. Materials are rich, yet understated.
The southern core space is highly efficient, mainly through the use of a single all-floor lift bank. Lifts open directly onto the open floor plate, providing a high degree of visibility through the office spaces out to the views beyond. The core is carefully designed to conceal all of the essential building services, such as goods lift lobbies, toilets and riser cupboards.
The result is a simple and elegant building form which will become a remarkable and memorable city landmark.
