If you are handy with tools you can make a lean-to hot house with a little lumber and buy the polycarbonate panels via Amazon.
Think A frame with hinges to lift one side to access the shelves inside.... and on panel with an auto open hinge.
The auto open hinges have a piston that is filled with temperature sensitive gel....it expands as the temp gets over 80 and then the panel opens to vent the excess heat.
Whole thing would cost about 300 bucks for lumber box of poly panels, and 2 hinges.
“buy the polycarbonate panels”
I bought the much cheaper “clear” ( but you can’t see clearly through it) 4 year greenhouse film. Has lasted 8 years and still doing fine.
Ha! Still have the link:

If making one for occupation T recommend getting clear vinyl for some clear windows. The vinyl will have to be replaced every year so don’t overdo it’s use..
