Hipsters hanging out inside of domes: not just for the 70s!
Young architect Kristoffer Tejlgaard and Engineer Henrik Almegaard sent over images of a plywood dome they built for the famed Roskilde Festival this summer, along with a making-of video, and it turns out the duo have innovated the formal typology in an interesting way.
Tejlgaard had volunteered at the Festival for several years, painting and building stages, but last year decided to submit a proposal of his own to build a small geodesic dome at the 2011 Festival. The organizers responded with a resounding affirmation, with a few changes: could he build it four times larger that he had originally specified? And waterproof it? And could they store a hot air balloon inside of it?
If you bone up on your geodesic history, you'll learn that one of the main reasons the geometry was abandoned was because of waterproofing problems: it was almost impossible to design a detail connection between each hexagon that didn't allow water to penetrate the envelope. Unlike older geodesic iterations, the Roskilde dome doesn't require joints at the apex of each side of the hexagons. That's because plywood accommodates a certain amount of tensile bending, allowing it to be CNC-milled as a series of flat sheets, then tensioned into place.
The plywood dome is designed to be deconstruct-able, and Tejlgaard, and it's possible to take it apart and insert modules into the hemisphere. This particular geometry is a C240 molecule, meaning that there are 240 hexagons in the finished hemisphere - compared to, say, the C60 molecule of a soccer ball.
Of course, "haters gonnna hate." Says one YouTube commenter (those bastions of cultural commentary), "4 trees died to build this shit?," to which Tejlgaard responded "Unfortunately, the trees were already dead when we got there, we just tried to make the best of it."
