Spherical Dome of Laminated Birch Plywood, Finland

At the Linnanmäki Amusement Park in Helsinki, the Owner wanted to establish a restaurant for children and youths, the form of which would reflect the shape of one of the most popular products on the menu. The Architect came up with an idea of a round two-storey wooden building with a diameter of about 17 m, whose shape is reminiscent of a hamburger. It was decided that the restaurant hall on the second floor should be entirely open and that the form of the ceiling should be convex outwards. In this context an idea emerged that the roof could be a dome with the load-bearing members left exposed.
