Starting the back wall** of my Tiny House took a lot of planning, but honestly I could have spent MANY more hours figuring out the layout/dimensions of things like windows and their location before starting. However, I am one that tends to plan and plan and plan and never DO, so I figured just jumping into it would be best. We started by outlining the wall and wheel well header, matching up the height of the wall with the short side (height wise) of the two end walls that we had already constructed, which was easy. Then we filled it in from there, building as I decided things. There was a lot of measuring my body and how many inches high my head and eye level are while sitting and standing to help with window placement. (I've decided that the best part of building my own house is making it customized to my body and life.)
**The "back" wall refers to the long wall opposite the wall with the front door. The two short/end walls are the "left" and "right" walls when looking at the front of the house. I don't know why I decided the label the walls this way, rather than "port" and "starboard", or "driver's" and "passenger's" sides. Maybe those seemed too nautical or vehicular rather than homey. Anyway, "front" and "back" just makes more sense in my head. And I'm not sorry.
It took a weekend to finish that wall. When we finally had it completed, Dad and I enlisted my mom, Susan, my bf, Nick, my sister, Brenna, and her bf, Corbyn to help us stand it up so we could all get a good visual of the height. It looks waaaay taller than I thought it would, so I'm pumped to start the last wall, which will be about a foot TALLER than this one!
