The structure of the Waitomo Caves Visitor Centre
comprises of an innovative ‘floppy pole’ system which provides spacing between
the interwoven pine laminated veneer lumber (LVL) grid. The weaving of the timber
structure to create a ‘gridshell’ is recalled by the local Hapu as a hinaki or
Maori eel trap.
Inflated Texlon® ETFE
cushions are cable ended and tethered over the gridshell structure. Each
translucent cushion is warped in plane and highly 3 dimensional; structurally
efficient in spans of 4-5m, and follows the lines of the LVL grid.
