well i talked the wife into letting me buy a poly tunnel and that is working great. got a frost protection system in there too and busy planning an automatic humidification setup for the springtime. Nanas are loving it even have an enclosure with undersoil heating for those 'special' ones.

Looks like those plans would work fine for a small greenhouse.
I'd add the following tweak though: If you use plastic to cover it, use uv stabilized greenhouse plastic.
It will cost you more, but it will last a lot longer. Also when covering it, go inside and cover the inside with another layer of plastic so that you have dead air space. One layer of plastic on the outside of the frame all over, then another layer inside with the wood frame sandwiched in between. That way two things will be accomplished, you will get better heat retention due to the dead air space, and your frame will last longer because the moisture won't get to it as quickly. The outside layer will need batten strips to hold the plastic on, but the inside layer can be just stapled up because it won't get as much wind and it'll stay on just fine.
We converted one of those Menard's carport/tents into a 12x 26 greenhouse and we built the end frames that same way. We put endwalls on it, installed wiggle wire and baseboard down the sides, put an inflation fan on it to inflate the poly, and it works great. We have also added a propane heater from Menards (garage heater) and thermostats/vent louvers/power intake shutter /circulating fan from Farmtek.

Why, you ask, is the shade cloth still on? I'm overwintering hostas in there, it keeps the temps from climbing as much during the day, and it's also a good place to store it, LOL! It's also good protection during a hailstorm.

These look like easy greenhouses to build and might do great with dwarf type plants.

Sandy, did you paint the pipes white or did you buy it that way?
I made a greenhouse out of the same type carport frame and I'm having some rust issues. Not sure if it'll make it through another season. I may try to get all of the rust off and paint it but, being such thin metal, I'm not sure that it can be saved.

Erlend,

What is the benefit of having the clerestory windows vs having a "simple" roof? Should that side face south?

I believe that they are hinged for opening to allow for more air circulation and cooling.
