Thanks for the feedback Ken,
I'm not sure if it would work as a tension structure, I plan to have a
frame of sorts. Perhaps as its similar to an Hexayurt H13 angles is some
areas, othere would like to comment or try it.
I wish to have a mezzanine floor with a hinged hatch for storage, located
around where the base of the roof triangles join the base, probably with an
internal frame, likely made of metalclad (Explanantion here
http://www.instructables.com/id/Clad-Composite-Beam-From-Waste/ )
I expect this to tie it together internally.
I am going to experiment with scaffolding pole frames & tube clamp joints
for a structure requiring more weight support, as the insualted walls will
be shelf like, holding veg plants in soil . These will be covered with
removable grp opaque corrugated sheets(see pics) . Wondering if such a
metal frame could be heated / cooled with internal water carrying pipes.

I showed a veteran roofer the model& mock up yesterday. He suggested the
walls were built slightly smaller than the roof, a frame of wood should go
around the top of the walls to rest the roof on with a small overlap of 25
/50mm to stop water ingress.
He also suggested the side could be hinged, so the roof opens up. He
thought the small triangle side could be a feature, perhaps put a logo
there.
I thought this would be a good spot to put an air vent or have a chimney
coming through if required
Sorry, the paper model is a bit wonky, I left a gap to show the small
triangle, but it should be as the full size mock up
Regarding the roof as as seperate small structure, I am 6 ft 2" and can
rest on my back with feet upright with little to spare.
It reminds me of a garden cold frame shape.

I imagine this has a better chance of being a frameless tension structure.
The low end of the roof could be attached to ground with tent pegs / L
shape rebar for stability
