The week started off on a high note, as we had our wonderful friends Rhett and Whitney visiting from out of town. Mark and I took a few days off from building to do a little hiking and a lot of catching up with them, and in the process realized that these were the first rest days we had taken since starting the build. Our aching muscles didn’t mind though, and our hearts and spirits were certainly lifted by the company of those who follow their passions and work to make their dreams a reality. After several days of campfires, hiking, good beer and even better company, we sadly waved goodbye to our friends, then jumped right back in and began work on building the floor joists for the tiny house (also called the deck).
Our basic design was to have two “skids” bolted into the concrete piers, and then to build our floor joists out of 2x10s on top of that. We constructed the skids by sandwiching a strip of 1/2″ plywood between two twenty foot lengths of 2×6 and bolting this “sandwich” together. This made the skids exactly 3 1/2″ wide, allowing them to fit perfectly into the brackets on the concrete piers. After some (okay, lots) of leveling and measuring, we secured the skids in place and were able to move on to the joists.
To get a tight and secure fit between the rim joists and the floor joists Mark used some good old fashioned ingenuity to make a “torniquet” out of an old climbing rope and a sturdy branch to pull the beams together and hold everything in place while we were nailing.
After adding spacers midway along the length of the joists -Voilà! We had the basic structure for our deck.
Since we live in a cold, cold climate, burly floor insulation is a must. With that in mind, we screwed some plywood to the bottom of the joists to make a cavity to hold the insulation (easier said than done), plugged up the cracks with expanding foam (because keeping pesky voles out of the insulation was also a priority) and rolled the R-30 unfaced fiberglass insulation into place.
Next up was stapling a vapor barrier over the top of the insulation, then placing and nailing the 23/32″ tongue and groove osb subflooring.
And now that we have a solid, square, plumb, level, and insulated deck, the real fun can begin!
