The structure is constructed from unsupported poly-vinyl chloride (pvcwithout reinforcing fabric).
The pvc is cut out using hardboard templates.All structures are glued together.
The structures have to work within very practical constraints:
-they should not be so big that they cannot fit onto potential host sites - perhaps even catering to specific sites
-they should be easily broken down into a convenient number of more portable elements
-they should allow easy drainage of water
-they should be relatively stable in wind
-the walkways should all be in contact with the ground to permit passage of wheelchairs
-the ceiling must always be well above head height to make it easy for adults to move around without bending
-there should be integrated strong and frequent anchor points
-the should work within reasonable overall weight limits
-they should recognize the potential deformations that can be caused by air pressure on unreinforced pvc
"They are flexible modular structures that can be positioned around trees, lamp posts or statues."
