It’s really coming together! This weekend we finished the walls and started sheathing. There’s a completely different vibe standing on the trailer now. Once enclosed, you can really start to visualize the space.
The green stuff you see is a special product called “Zip System.” Rather than simply using standard OSB or plywood, this stuff has a waterproof coating on one side. Each of the seams will be covered by rubber. This creates an air and water barrier around the whole structure. It costs a bit more but it appears to be well worth it.
