We build with concrete and steel and 2x6 walls. We use spray foam insulation and good materials for flooring and trim that won’t wear out tomorrow. We build for about the same as it would cost to take an existing house; demo out all the stuff that doesn’t meet code, make it meet code, then put back all the good materials that won’t wear out tomorrow. Trust me your big line items are still there when you refurbish something to meet codes; and governments aren’t going to fund projects that don’t meet code. That is before you even get to the discussion of what people actually want their finishes to be.
