Is it possible to put a door in a Cantilever Bay Window? We are considering adding a door to a bay window that will lead to a new patio but we're not sure if that is possible. Does anyone know what typical city code would require if it is possible? I'm worried about the need to add concrete supports under the window. How would you dig the holes with such little clearance. Anyone ever done anything like this? The contractor that I typically use is not sure, he's never done it before.
Adding a door to the space occupied by the central window would not be a structural issue; you would in fact be reducing weight on the existing joists. (Presumably the floor joists there cantilever out over the foundation)
Your deck could be free-standing, with no tricky connections to the foundation.
