The solution was to combine both the greenhouse and storage shed into a single building with the roof of the shed being taller than the greenhouse. The idea is that the shared wall between the two buildings can be insulated, so that one wall (north side) of the greenhouse isn’t exposed to wind. With the greenhouse roof being somewhat low to the ground, it’ll hold the heat in closer to the ground (think along the lines of a “walapini”). I also built it at the lowest point on my property, with the hope of retaining ground moisture in and around the greenhouse.
Clearing Land
So we started! We harvested a few trees (used for firewood) to clear an area for the new building.

Tip: We used our pigs to help clear the rocks and roots from the area. They're like free excavators!

And we started the framing.

A big thanks to Joe “Bebop” Stenson for helping with the framing. Given that this is my first project of this nature, I didn't want to risk wasting any (expensive) lumber!

Now that we've had our first snow, photo proof! This came down as around 10 inches of heavy, wet snow.
