The design provides a regular/irregular spiral stair forming a double helix that cantilevers out over the water within a wharf cut out, standing on four existing piles.

Constructed completely out of pipe and angle, comprising over 600 unique parts and an astounding 400 lineal metres of pipe.

With every single pipe section forming an integral structural member within this complex structure, this was no straight forward Structural Steel build for the team at Stevensons.

Due to its unique shape and form the entire structure was fabricated in its entirety on a specially designed support frame before being cut into two pieces for transport to the site adjacent to Te Papa.

When installed the top platform gives an impressive 8.5m drop into Wellington harbour at low tide or for the less brave a secondary exit 3m lower.

This Platform was opened to the public by HRH Prince of Wales and Duchess of Cornwall on the 14th November 2012 to much fanfare and has since won a Distinction in the Rural/Park/Recreational Landscape Design section of the 2013 NZILA Awards and a Wellington Civic Trust Award for Innovative use of a Public Space.
