TECHNICAL: The geodesic dome, the starting point, is a frequency four, its great circles forming the lines that are cut along in the splitting of the surface.The chipped sphere surfaces are scaled from the center of the sphere and therefore remains true to the geometry.

The surfaces in between becomes radiating, perpendicular to the spheres surfaces.



The ambitions of the system was honored by 3D-modelling the entire skeleton. Printed nodes that are laser cut and robot welded, meet the high precision requirements of the lattice structure.

The nodes are designed as steel shoes that are open in one dimension and two inches in the other, so they can accommodate the family of standard rafters.

In collaboration with our engineer we developed a table with the differend stresslevels. It generates the dimensions for the timber to be used for the different struts.

This dome used 2x4 inches and 2x6 inches construction timber and same size plywood-beams, a total of four different strength classes,

to minimize material consumption.



The dome was set on the site with half nodes, as in all other intersections of the surface. The ring of nodes were attached to inward pointing beams, that were weighed down by 18 tons steel plates, that formed the floor and prevented the dome from lifting in strong winds.

The building envelope consisted of translucent greenhouse membranes on the spheresurfaces and transparent PVC film as windows on the perpendicular surfaces.

All the wood used for the facade, flooring and interior is local grown Douglas pine.Because the project was temporary, the façade was made of old boards that could be only difficultly used for other purposes.
