I've found a few, small, claimed to be pyramid greenhouses, but they are more TeePee than pyramidal.
Angles are too steep, six panels instead of four etc.
A greenhouse would be a nice addition to my gardening endeavors and one of the nice parts is, we have quite a bit of 1" square steel tubing.
Lightly rusted, but that's no big deal.
Grind it clean where it will be welded, power sand the flat surfaces and either leave it as is or paint it with a rust converting paint like
Since the sticks of square steel tubing are 20' long, cutting them in half and building a 10' x 10' base would be a doable deal.
Granted, the room at bench height - 36" or so - would leave you with an area of about 5' + and there would be enough room to run some small
experiments over the winter.
Thinking is, the upper half could be sheeted in Lexan - trade name for polycarbonate plastic - which is similar to plexiglass, but considerably
stronger and resistant to ultraviolet rays.
Fwiw, I have Lexan windwings on my 32 roadster and after about ten years of use they are quite clear and still look like new.
Venting the pyramid would be easily accomplished with a simple manual window opening device.
Aside fom all that, other than the novelty value and keeping in mind all the stories about what happens to things in a pyramidal structure it looks
like a pyramid shaped greenhouse could be advantageous over a square or rectangular one.
A true north orientation would be easy to accomplish in my yard.
Not sure where I'd find the time to build one, but it strikes me as an interesting experiment.
