The timber based part of the egg is essentially a panelised structure with ribs and a shear diaphragm. Like a timber frame house really - but bent. The panels are nominally just under 1200 wide to suit standard cladding sheet widths. Ribs are made from 45mm thick Kerto 'Q' Laminated Veneer Lumber. Supplied in sheet form, it is CNC router cut to 200mm wide curved profiles and finger jointed to lengths.

The two dimensionally curved cladding panels are pressed from a combination of Finnish Birch Plywood and OSB4 to a robust 18mm thick unit. After assembly the units are shipped to a local GRP specialist to have the resin and glass fibre lay-up applied and finished with the blue flow coat.

Heavily dependent on a full and accurate computer model, the evolved shape does not readily pigeon hole into convenient terms like Ellipse, Arc, Parabola - an art form as much as a structural solution. It is 13700mm wide x 8500mm long x 5800 high supplied in 30 panels.
