= H13 =
The H13 is a brilliant improvement on a longstanding hexayurt problem. 1 more panel gets you increased standing room and a face on which to put a full-height door.
Inventors, family, variations
- http://hexayurt.com
- Vinay Gupta invented the basic shape for regular hexayurts and a number of variations, and placed it in the Public Domain. This allows others to develop the original idea further. Known developments are here, also in the Public Domain.
- Scott Davis and Dylan Toymaker invented the H13, which solves one of the oldest quirks of the hexayurt design – how do you get a full height door way? Scott took a creative leap, switched around a couple of triangles, and came up with a design which for just one additional sheet of plywood gets you a structure with a full 8′ entry-way, much more interior walkable space (see below), and (subjectively) a much better over-all aesthetic. It's here. Vinay regards it "a fantastic piece of work", and "suspect(s) it will become a very common hexayurt in years to come"

- Also show how halves on the side create a different shape with the same volume, only flatter.

How to build it
This PDF 
can serve as a guide for making an H13 hexayurt, with the option of using the Camp Danger Hinge Technique. (hinges make the yurt prefabricated and semi-folding using only tape, meaning much less construction work, no mitering required.) The Hexayurt Camp Danger two part folding site gives instructions on creating the tape-hinges described in the PDF; between those two resources it should be very easy to create an H13 as a semi-folding yurt. Warning: this shape yurt has not yet been built using hinges, it's still theoretical, but it should work.

They can be built in "threes", like 1/16 of http://dylantoymaker.net/toybox/2010/10/20/hexayurt/ and in "nines".

Standing room
Regular hexayurts are built with 12 panels: one for each of the 6 walls, and one (cut through the diagonal to make triangles) for each of the parts of the roof. If the panels are 4' x 8', then the roofs go from 4' to 8'. Height of human adults is between 5' and 6' (and our heads are not a thickless line), so standing room is, say, slightly over 50% of the floor.
The H13 uses 13 panels, and standing room is not 6 "B" triangles but 6+4, a 67% increase.
H14, which uses 14 panels, has even more standing room: more than twice the good old H12.
