= H13 =
The H13 is a brilliant improvement on a longstanding hexayurt problem. Compared to the common 8' hexayurt, one more panel gets you increased standing room and a face on which to put a full-height door. This would be a great option for Burning Man participants. It is "H13" because it uses 13 panels instead of the 12 required for the standard 8' hexayurt (and, doesn't that name sound awesome?)
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 Hexayurt Hinge Technique. (hinges make the yurt prefabricated and semi-folding using only tape, meaning much less construction work, no mitering required.) The Camp Danger Hexayurt Hinge Technique 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 8' hexayurts are built with 12 panels: 6 for the walls, and 6 (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 goes from 4' to 8' at its peak. Height of human adults is between 5' and 6', so there is proper standing room in, say, slightly over 50% of the floor.
The H13 uses 13 panels. One half of the roof is the "classic" shape, and one half of the roof is increased to 8' (so far called a "gable" or the "tall half,") and standing room is not 6 "B" triangles but 6+4, so a 67% increase.
The (currently theoretical) H14, which uses 14 panels to put the same "gable" shape as the H13 on both sides of the hexayurt, has even more standing room: more than twice the available standing room of the good old H12.
