Greetings, fellow urglers ;-)

I've made a page about triaxial polytunnels.

[snip http://hexdome.com/triaxial/polytunnel/]

It looks sensible for a permanent structure, but for a small garden
polytunnel of the type that you use as a cloche, rather than walking into,
you need some way of making it collapsable. The typical concertina type can
be folded into a small package for storage but I think it would be more
difficult with your design which looks ike it would be strong against
compression in all directions, not just in the directions needed. a normal
polytunnel with a guy rope at either end keeping it in tension would be more
practical I think.

Yes: the structure was intended for semi-permanent use.

Making it collapsable was not a significant design consideration.

If you wanted to take it down, you would indeed have to dismantle it.
