Fellow DIYers, I'm looking for input/advice/comments on adding an exterior door to my house. Currently there is no access to my back yard, except through the garage. We are renovating our kitchen and it is down to studs. There is a nook with a large window in a non-load bearing exterior wall we would like to replace with a door. Are there any red flags I should look out for?
Below is a picture of the window and wall. The corner you see on the left is the edge of the load bearing wall, and a beam extends across above the ceiling. The couple feet or so that the wall is pushed back extends out from the house.
The window is wider than 3' so we may put a narrow, vertical window section in. The rendering below kinda shows what we are planning for the door.
We would love to do this ourselves but I wanted your take on it before I sawed a hole in my house. :devil3:
