   shemp,

   If I'm reading you correctly here, it seems like enlarging the area where the fireplace was will leave the existing footing for the fireplace as sort of just an area of redundant concrete. You can add a new footing for the bay window and either pin it to the existing footing/foundation or float it as a separate entity.

   Or possibly you could use the footing as is, and cantilever the framing for the bay window off of that, but I can't tell from the post because I don't know how far below grade the footings are, and if there is a frostwall or full basement involved or just what exactly, but those three options would tend to exist to one degree of practicality or another.

   One thing I can figure on is that if you remove the old fireplace fairly carefully, you'll have a nicely compacted base from the weight of it for however many years it was standing there, not likely that the new foundation would want to sink.

   Thanks for the note. I was guessing I didn't need to attach the new to the existing. I think I'll just pin it at the ends. No basement just a crawl space. No frost issues, this is the Seattle area and all we worry about is rain. Can't cantiliver off existing because this is one of those houses that doesn't have traditional floor framing but 4x6 on 4foot centers covered with 2x6 then the house build up from that.  Thanks for the help.
