I am building a tiny house on an 18 foot long 8 foot wide 10k double axle trailer. It's my first building project and I have a deadline of August 24th when our lease is up. I'm using locally sourced and milled lumber and sheep's wool from Oregon Shepherd for insulation. The roof is a Corten corrugated steel roof. I'm going with no plywood, no vapor barriers (except tarpaper against metal surfaces) and air gaps between my insulation and my siding to try and build a breathable wall system. No bathroom, we are happy to poop in the woods. The shower will be a showerhead coming out the exterior and we will build a little outdoor screen wherever we land. The sink will also have mirrored plumbling to the outside allowing an exterior sink to be attached as well. I hope to hear your advice and experiences as my build progresses and learn from you all.
Started in May, which is subfloor/floor month. June will be framing/roof/exterior siding, and July and August will be everything else.
Here are my plans to begin with:
The fridge will be propane... same with the stove and the on demand hot water heater.
Trailer with aluminum flashing and tarpaper attached
Attaching 2x4s with self-tapping trailer deck screws. 2x8 joists will be nailed into these. Most of my lumber is spruce- light and strong
Screwing and nailing in the joists (went with both)
Subfloor and sill plate finished. 2x4 furring strips bolted and screwed in. The floor will be 2x6 shiplapped fir that will run horizontally, nailing into the furring strips and the joists. The sill plate pictured is some reclaimed old growth redwood, which is also bolted and screwed in. Finally, there's 1x wooden spacers attached across the bottom. I stapled plastic nursery netting to this, and it will provide my air gap for my wool insulation. Theres my newborn baby too
I welcome all comments and will update soon! Thanks!
