Here is the platform build for the tiny house. My job during the build is to watch the kids, so forgive my lack of details. They started out by laying the beams on the cement blocks. Lots of measuring to be sure everything was square.
The beams don’t span the length of the cabin, so they clamped and then fastened them together.
They used temporary posts and stacked them until everything was flat. Lots of checking with a level and lots of measuring to make sure nothing was moving.
Once everything was flat, they put the joists in. Then they went around and made sure everything was flat and square again.
The smaller pieces of wood are attached at the bottom of the joists to hold up the insulation.
The posts are still the temporaries because it is better to put the final posts in place when there is more weight on them. I assume this helps ensure that it is flat when it’s done.
The insulation going into place. There is enough room between the insulation and where the floor will be for piping and maybe someday wiring.
The final floor boards in place.
The walls have been started here and then they finally put the final posts in place.
