Bend Active

The initial aspiration of the project was to produce a method of simplifying the construction of the 5 regular platonic solids (Tetrahedron, Cube, Octahedron, Dodecahedron and Icosahedron) using only bend active timber and simple bolted connections, eliminating the need for complex nodal connections as seen in geodesic dome construction and other compound angle connections.

platonic solids

Bend active timber being the main research topic, the structural capabilities and bending radii of plywood were physically tested incorporating the several thicknesses and crucially the direction of the bend either being parallel or perpendicular to the grain, resulting in an informative results matrix.

Digital explorations were undertaken for each of the platonic solids creating various sized volumetric frame structures. The resultant sizes were due to each component being constrained to fit on a standard 2440x1220mm plywood sheet and the resultant bending radius

Following physical investigations of each, the cube was taken forward as it was; more efficient in terms of material usage, easier method of assembly comparatively and unintentionally produced a deployable mechanism similar to the famous Hoberman’s sphere.

The system utilizes identical components meaning the fabrication process can be quickly and easily performed using a CNC machine, with assembling being intuitive, not requiring different parts or specialised assembly instructions. The components were cut using my own CNC and were then simply assembled by hand using bolted connections to create the skeletal frame. Assembly was extremely quick, from flat components to finished volumetric module taking only 20 minutes.


The pre-fabricated modules can then be replicated and scaled, to suit various habitable typologies a community would need or can be used individually as a deployable shelter for the homeless/emergency relief.
