Wicked Tiny House - Interior Construction
With the exterior fully weatherproofed, it was time to move inside, and just in time too, as it was the end of December! The first task, clean out the inside and start with a blank slate. Out went the clawfoot bathtub, old rough cut boards, old windows, and everything else that had stored in the house.
First up, insulation! I was able to get a great deal on factory seconds of 3" thick pieces of foil faced polyisocyanurate rigid insulation, which provides an R-value of 6 per in. The previous owner had insulated the floor with fiberglass batt's (the pink stuff) which isn't the best choice for tiny houses. The vibration when moving the house can cause the fiberglass insulation to settle/move, resulting in reduced R values. That, and he had installed it before putting the roof on, so the majority of the insulation had gotten wet and was beginning to mold in places. After removing the old insulation, and replacing some of the subfloor material that had started to rot, the floor was installed. Next came the walls, and then ceiling. Any gaps were filled in with Great Stuff spray foam. It took a long time cutting all the insulation to size and filling in all the gaps. The result was a huge mess, but a very tightly insulated house.
Next up, roughing in the electrical and plumbing. I wanted the house to be both on and off grid capable, so figuring out the utilities took a lot of research, trial and error, and a little bit of experimenting. I had almost no electrical or plumbing experience, but I borrowed some old books from my dad, and went to town. I did a rough electrical layout on paper and planned for five individual circuits, with all the lights on two circuits, and all the outlets on the other three. The reason for having the lights on two separate circuits was so that in the future, if I am living off grid, I can convert those two circuits to 12 volt, and run the lights directly off the batteries, rather than having to convert the power from DC to AC and then back to DC to run the lights.
