want to add a small addition to our kitchen. the addition would extend out under the soffits of the house (14") and would be 6-7 feet wide. The exterior wall will have a window and door added. So basically it will be a box or bay addition sticking out the side of the house. What is the best way of building the floor. Do I cut the header at the end of the floor joists and extend the joists out? or do I just use hangers and add the joist to the floor header (the one that is sitting on top of the concrete basement wall) from the outside? Thanks for any replies.
