My wife and I are considering a bathroom addition that would be about 10'x10'. It would be right next to the master bedroom and would also butt up against a porch. The mast bedroom is on a traditional foundation and the porch is on cinder block pilings. In the interest of saving money I am going to do the electrical, and most of the interior work. I am also going to be GC. My question is about the foundation. I know that the way I do it depends on local codes etc. however, is there a reason that I need to have a cinder block foundation going all the way around the addition perimeter? I already have the traditional cinder block foundation on one side and perpendicular to that I have the cinder block pilings. I'm thinking that I just need 1 more foundation wall parallel to the porch wall and perpendicular to the existing house wall.
Your thoughts would be much appreciated.
