The east wall and sill is going to be bumped out four feet. 

 We've decided that the north wall (the one that separated the main portion of the house from the kitchen addition is going to disappear.  Martin is planning on taking out the sill temporarily, but putting it back in to support joists for the main floor. This wall is disappearing for a couple of reasons. If you look at our floor plans, most of this area is going to be open.  Also we need access to inside of the house for the backhoe (the one the neighbor is going to bring over to help us dig the basement). The north wall is the least load bearing at the moment, is the easiest to take out, and offers the best access for the backhoe.
