The design for the restaurant roof focused on developing a simple fabrication system within the confines of a complex geometrical form.
The principle behind the form of this new covered restaurant in Mauritius began with a simple Buckminster Fuller-esq series of triangular panels, which would be connected to form the shape. The challenge though was how to form the panels and how to ensure the structure could be built safely, easily and as cost effectively as possible in a country that regularly gets battered by typhoons.
A number of options were considered at the outset with the aim of creating the main structural elements overwhelmingly from timber. Eventually it was decided to focus on the panels themselves creating panels where all elements were planar therefore prioritising ease of fabrication of the panels.
To resolve the panel-panel connection where the geometry dictates sharp discontinuities forming, steel nodes are proposed which allow 6 (in some cases 7) panels to come together in a controlled manner. This ensures adequate force transfer between panels which are particularly onerous due to the typhoons experienced in Mauritius.
An investigation was also carried out on trying to maximise the efficiency of the roof's shape using a genetic algorithm within Grasshopper. Further rationalisation was also carried out based on the constructability and to ensure the interface between panels was achieved cleanly.
