Hi
I'm just about to start work on building my extension, but I have a question that I hope somebody will be able to answer first...
I have plans for the raft foundation, but the design is for a single storey extension as that is what I had planned on initially. I've now changed my mind and decided that the extra space a double storey extension would provide would be useful.
Do I need to make any changes to the raft foundation plan (i.e. deeper, extra reinforcement, etc.) to ensure it'll support a double storey extension?
Also, there's no mention, on the plan, of how to tie the raft foundation in to the existing standard foundations of my house; do I not need to do this?
Thanks.
