Abstract
The design of curved structures is complex and often leads to the development of intricate systems that are costly and difficult to assemble. A recent approach, developed by Architectural Geometry, consists in translating constructive expectations into geometric properties so that they can be taken into account as early as possible, during the choice of form.
This work studies a family of specific surfaces, called Voss surfaces. They can be constructed from simple elements, straight laths and flat panels, and standard connections. Voss surfaces possess numerous geometric properties that will enable the formulation of design tools for the generation and alteration of geometries.
These tools are applied to the realisation of a pavilion called Geogami. The design stages are presented, and detail the choice of materials and techniques. The pavilion thus demonstrates the constructive value of Voss surfaces.
