Once we finished assembling our quonset hut, the next step was to build the end walls. We opted to build our own, rather than purchase them as part of the building kit, so that we could completely customize the size and placement of the doors and vents.
First, we screwed pressure treated boards to the cement to form a sill that we could build off of. We used our own rough cut lumber to frame the walls, doubling the boards in some places to reach the quonset hut’s 14’ peak (our sawmill only allows us to cut 10′ logs). Deciding how to secure the upper part of the wall to the curved metal structure was a bit tricky. We ended up putting roofing screws through holes that we drilled in the drip edge, which can be seen as little green dots in the photo below.
For siding, we used upcycled roofing steel. To get the steel to match the shape of the quonset hut, we had to carefully cut each piece. Brandon would stand on a ladder on the outside holding a sheet in place, while I stood on a ladder on the inside to trace the curve of the drip edge. We then cut along the line using tin snips.
Although you can see some light along the right side of the wall, the drip edge overlaps the cut edge of the roofing steel by a few inches, preventing water from leaking in. We will evaluate whether spray foam insulation is needed to fill these little gaps, and if necessary, we’ll tackle that project in the spring. For now we’re just focused on getting the building closed in to keep the animals out of the wind!
