Hello all. I have been debating on whether or not to stay in my house and add on,or to just sell. I think it would probably be cheaper on me to sell and buy what I want, but right now Im exploring all my options. One thing I would like to do is widen my living room. My house is wood framed and sitting on a block foundation all the way around. There is a small porch that spans the length of my living room and is about 4ft wide directly on the outside of my living room. I have went under the house to look at it and it's just a "cap". The block foundation runs under the living room wall the length of the living room and the concrete porch cap spans between it and the outside block foundation. Could I just build a wall on the outside of the porch, knock the current wall of the living room down and be done with it? (if I could match the height difference). The floor joists stop at the existing living room wall since the porch is just a cap. I wasnt sure if you would have to bust up the cap and install floor joists or not.
