The House that Phill Built

I have managed to find a cash-in-hand job helping a friend of a friend build a house. However, I do wonder as to this house's structural integrity due to my coimplete lack of knowledge of how to build stuff.

This is a picture of the garage, I've been working on the wall on the right.

Here I am working while my friends were at the snow. It looks like I was with them too, but I'm just covered in polysteryne. I am also sideways.
