		<description><![CDATA[This space frame trellis is a hybrid between an arch and a pergola.
It is formed from four pyramidal units bent into an arc and propped by two internal V-shaped supports.
The structure works like a three-hinge arch, which makes it not susceptible to differential settlements of the foundation &#8211; pegs in this case.

		<description><![CDATA[These surfaces are referred to as Schwarz’s periodic minimal surfaces, in honour of the mathematician H.S. Schwarz who first explored them in 1867. These periodic minimal surfaces can be tessellated into hexagons and heptagons consisting of equal length edges, The design of this highly efficient structure was inspired by recent research in Fullerenes.
