Dodecahaven
Use 4 7’8" 2"x4" wooden posts
rebar'd into the ground (in a square).

Place 8’x4"x4" wooden posts vertically
at each corner (bolted to base) with L pieces of metal.

Bolt 4 8’x2"x4" at top of verticals
notched into the verticals.

Add 2 8’x2"x4" verticals for door.
Add 4"x1" planks bolted diagonally
to keep cube stable.

Add 2 8’x2"x4" non-door for bed support.
Add 4 8’x2"x4" horizontals for bedsides.
Use metal L-brackets for stronger support.
Cover with plyboard for bedbase.
Add plyboard bedside to wall, and posts on
the inside bedsides, to prevent roll-offs!
Foam/airmatresses on plyboard & ground.

Cover cube with plastic, except for door.

Actually 8’ is the size of the cube side,
so the 4"x4" posts above will be 7’8"
to compensate for thickness of the beams.

Add rooftops to each side by
separately assembling squares with crafted
1" slats screwed on.
Calculated length of struts is 59.33 inches.

Note: front door "rooftop" is hinged at top.
Need 2 extra 8’ poles for door support,
when door is horizontal to become an awning.
Good for shade (or rain cover),
eg for cooking and chillin'

Cover pentagons with 4 sheets of dual
attached pentagon shapes of plastic,
by stapling to wood.
Remember small half pentagons which are
close to the ground.

Note: door will cause one dual-pentagon
sheet to have clipped triangles at edges.

Calculation of lengths

I did my own (from first principles) calculations to get the lengths based on an 8’x8’ cube (because that's what wood comes in, and the plastic sheet comes in 8’4" widths too), but visiting: http://cage.rug.ac.be/~hs/polyhedra/dodeca.html they show nicely that the sides of a pentagon (ie my struts) will be (sqrt(5)-1)/2 (ie 0.618) of the pentagon "diagonal", which is my 8’ cube size.
8*0.618 = 59.33 (almost 5’).

A little bit more calculation shows the rooftops peaks are about 30" away from the square base, so the dodecahaven will be a total of 10’6" (or 3.20m) high.
That should be impressive!
