i Have a greenhouse kit that youngest DD bought me some 3 years ago, A lot of stuff has happened since then to prevent me from putting it together. I even foresaw high winds from rolling it away to my street fencing by purchasing two 10' 4'x4's and two 8' landscape timbers to sink screws into all of the corners--it is a lean-to design, 4'x6', and, just like wooden fencing timbers you need enough buried underground to keep it secure. I haven't finished all of my research for Type but something Like this should do to countersink screws into the aluminum skins and into the 4 wooden posts.
I anybody here has suggestions, please post!!

For fencing, an 8' 8" diameter post is buried 3' down, 5' above, but those are holding up Other fencing materials.
I believe that 2' underground should suffice for this project.
I HOPE to build it later summer, early fall.
I do NOT intend to electrically heat it. I will save up soda 2 liter bottles and let solar heating keep it marginally warm.
I also, if I intend to use it next winter, will need to simply create a "wind wall" with removable metal fence posts--I have extras--and a piece of 4'x'8' plywood to directly block the severe winter winds that we get here. I guess if I can take the time to paint it with some mistint paint it will last longer than a couple of seasons. I certainly have space to store this.
Such will also be for my shed over the Inner Sanctum cistern, which I will probably have built by somebody else. THAT will Have to have new outlets, so I will be asking my electrician to see to it. They (the company,) will need to be sure that the electricity run underground some 20 years ago has not been damaged over the years from exposure. Then I need outlets on every wall, one exterior outlet to plug into, and an appropriate electric heater to keep the building at 45 degrees F, so that the water pump doesn't freeze, crack and break like the decrepit pump rusting away over it currently. I don't care if the builders insulate it or not. I can do That myself. It will need to be built with wood so that, like my wooden barn, will breathe and will retain heat.
A metal or plastic building won't do. They fry in the summer, freeze in the winter, and I'm not even sure are a good place to store your mowers, but this is a matter of opinions. Certainly, if you have a fenced in small back yard that type of building is very reasonable and affordable.
I also want 2 windows in this building, one south facing, above the entry door, and another east facing. A west facing window will be prone to high winds and excessive weathering. DD's and I will do shelves. I intend to store my numerous watering hoses in this building.
During the summer I will put my heated hoses in there, during the winter I want to have hose reels attached to the walls for storage. My hose storage last winter was hackneyed but it kept them in one place, so excusible.
My 115+yo house has west windows but NONE on the 2nd floor, and only 1 west facing window in the basement, none east facing bc Something?!? is under the porch and we don't know what that is. just that a south facing window-to-nowhere exists and none of the 3 of us is brave enough to take it off and look.

ALSO, most important, this will end my 25 year stretch of running a hose to the house to fill my horse's water tank. The cistern is some 50' to the entrance of my barn. I am sure that next winter I will patting myself on the back for Finally achieving this milestone.
