Show me the money!

We had our third meeting with David, the architect today and he has come up with a concept plan for what will be an absolutely beautiful house.  I am less than thrilled though, as I have a sinking feeling that it will be way over budget, as he seems to think that to achieve our brief, we would be better off demolishing and rebuilding.  Now, while I am all for this, the budget says "NO!" I have been in a position before where we built and lived in an amazing house with an amazing mortgage to match.  Never again - the stress nearly killed me.  Every meeting of the reserve bank would have me breathing into a brown paper bag.   Before we go any further, we will need to price it.
