I am happy to report that we cut all of our 10 foot monkey hut poles in half and had great success.
We made sleeves to reattach the 5 foot sections together using 2 foot sections of 1 1/4 inch PVC with a screw driven into the middle (so it would not slide down the pole it was on)
We anchored the hut to the ground using only the pieces of rebar recommended in the instructions. We added an extra 5 foot section to the structure as well.
We used a ton of bungie balls to attach a big piece of custom cut shade cloth to it, and did not anchor it to the ground at all. We did put a few very tight bungies wherever we could though on the parts of the cover closest to the legs/rebar
We used quite a few bungies going parallel to the roof supports too, to pull them all together.
We did use a shade cloth, which was 90% light blicking, but still allowed air through. I think this lead to a much cooler structure during the day. I had assumed that the breathable cloth would cause less wind force on the structure, and that may be true, but when talking to the manufacturer (http://www.thenaturalhome.com/shadecloth.htm
) about another project, the told me to use the same wind load calculations as a solid surface.
We actually have had it up it the backyard since February, and we even have a normal tarp over part of it now. We live in CT, so we don't have playa-wind to test it, but it handled the end of a snowy winter and a crazy New England spring with no issues.
My biggest caveat about cutting the PVCthough, is that it takes up ALOT of room once you cut it. We stuffed it (and a lot of other stuff) into a Neon for the drive, and while it fit, the monkey hut (and shade cloth) probably took up the most space of everything we had.
