Large dome shape made out of 340 pieces of card-board all working together as one surface.
Each triangle is small enough to be made out of reclaimed card.
Circles of varying diameter can be cut out of individ-ual triangles to make the shape let in more light and be more transparent.
How it works
The full dome is made out of 360 triangles (of 6 different types). Quantity of each triangle is also a multiple of 6 (i.e. 30, 60, 120). The diagram below shows
The shape consist of 6 large identical hexagonal surfaces, joined together by larger triangles.
Entrance to the dome is hexagon.

Sizes and quantities of triangles to make
- Trace over the stencil.- Cut along the traced line with scissors. - Score the cardboard along the red line with a craft knife. - Label triangles and mark different edges- Sort triangles into piles for easier assembly after-wards
- Staple triangles together following the pattern of the left. Flaps should match up.
- To make the entrance staple triangles together following the pattern of the left. Reinforce the flaps on the internal circumference with extra layer of cardboard so it make a solid edge.
- Staple triangles together following the pattern of the left.
- Join 5 hexagons made in step (2) and (3) together with 5 triangles made in step (4). It does not matter where the entrance goes. The shape should be flex-ible at this point.
- Add 5 triangles made in step (4) to the shape made in the previous step. It would be easier if one person would be inside the dome.
- You might want to leave some connections loose to make positioning of the final hexagon easier
- Join two ends of the chain made in the previous step.
8 - Carefully lift the final hexagon in place and staple the edges together from the inside.

The shape is slightly larger than a half-sphere with the bottom being 400mm below the split line. This should give a visual effect of the shape being buried in the ground.
It is made out of branches tied together with cable ties. Smaller lengths are bunched together to make longer and thicker sections.
Twigs with leaves and greenery can be added in the final step to make the shape look more solid
Make 3 circles of diameter 2.5, 2.35 & 0.7. Their cir-cumferances need to be 7.8, 7.3 & 2.2m respectively.
- To do this first make single line lengths which are longer than the needed circumferences (by around 1m). Use multiple branches for each length to make the final rings stonger. -Secure bunches together with cable ties, but do not tighten them yet. -Mark out lenths of needed cicumeferance on each length. You should have 1m extra in each bunch. - Join circles together so that their ends overlap and one end touches the marker. Lay out another couple of branches along the joint so that one length joint together two ends- Tighten all the cable ties.
- Make 5 lengths of 4.9m for the arches by bunching together smaller branches with cable ties. - Put cable ties on the ends. - Mark their mid-points.
- Mark 0.78m lengths along the circumference of smaller circle made in step (1). You should have 10 markers at the end and they should all be equally spaced.
- Bend arcs to that their ends join the circle on per-pendicular sides of it. Cable-tie them in a criss-cross fashion as in the detail.
-Make sure the tops join at the mid line marked in the previous step.
-Cable tie the top together.
- Place the entrance circle along one of the arcs and mark where it goes.
- Tie additional supports for the circle to the arches and horizontal circles as shown on the diagram.
- Tie the circle to the supports and the arch.
- Cut the arch below and above the circle as shown in the diagram.
- Pull the larger circle over the top of the shape made in the previous step. It should be around 800mm off the ground at this point.
- Cable tie the circle to the arches in criss-cross fash-ion (as shown above)
- Weave smaller branches in between the main structure following the pattern on the diagram. These branches can have leaves on them. Distance between twigs should be determined by the amount of branches you can source.

Structure made out of flat panels arranged in folded fashion. The stability is achieved by the pieces leaning towards the centre.
It is assumed that the structure would be pre pre-fabricated beforehand (on a CNC-router) and purely assembled during the workshop. Pieces will be joined by cable tied through pre-drilled holes. Each part is numbered for easy assembly. Alternatively it can be made using a circular saw and a hand drill.
Some panels can be made out transparent mate-rial (i.e perspex, polycarbonate) or with cut outs to give the interior more light.
Location of parts
- Connect the entrance to the roof by threading cable ties through pre-drilled holes. Do not tighten them yet.
- Connect 4 back panels together to each other.
- With one person holding the entrance, one holding the back panels and one holding the roof, connect the back panels to the roof.
Connect the rest of the penels to each other and to the roof using pre-drilled holes and cable ties.
