First Look: Foundation Assembly

Foundations are *by far* the thing I've spent the most time researching, looking at different assembly drawings, and trying to understand. There are so many different approaches it can start to make your head spin, especially if you don't come from a building background. TBH I'm still not on totally firm ground. (End of foundation-related puns ... for now.)

One constant in my mind has been that bedrock is near, so we should use the foundation Mother Nature has generously provided. It's as good as it gets. There is 4' of soil on top of bedrock at the thickest points. At the MVC site it's more like 2 feet, and at the northwest corner of the volume it's basically exposed bedrock.

The other piece of the puzzle is that we're cladding the structure in a full stone wall, so that has to sit on something hard.

So with the help of our timber framer — who also builds whole houses — here's where we're at right now:

Points to note:

  • For the stone wall, I wanted to start it directly on the bedrock, but in the interest of time-to-market we decided to go with a 2' wide concrete wall rebarred into the bedrock. I can't let my time-consuming, amateur stonework block the structure's erection. 🤭
  • 2" of foam is shown here, but we're still looking at foamed glass aggregate — specifically Glavel — as an option. We already have loads of foam in the Structural Insulated Panels (SIPs) that's giving me anxiety. (Much more on SIPs to come.)
  • Adding to the anxiety is the amount of concrete, but given the site, the building plans, the timeline, and its familiarity to most masons, it's a logical route.
