Addition to load-bearing cantilever
Welcome to the Forum!
certainly some photos would aid us in providing some useful comments. What is the depth of the cantilever? does the roof bear upon the cantilevered wall or is it a gable endwall? how is the sunroom to be constructed, roof type, cathedral ceiling, etc.? I could go on with more questions ...... many items have to be evaluated before a simple question can be answered.
what is your building code? do you construction drawings? are you required to file for a building permit? just a few more to think over
