I've spent the past 4 weekends helping build the foundation for the house my brother is building. I do not enjoy foundation work.
Now that the walls and pad concrete has been poured, he's onto thinking about framing the first floor. He asked me to take the measurements with him and put it into SketchUp so he can have a cutlist to work off of.
This. Took. Forever. OMG. I didn't know how to frame walls before, but I do now, and I don't care for it :P Timberframe all the way, IMO.
