2nd floor addition supported by post and beam
Hi hope everyone is doing well. I have a question on a future addition. I have room on the back of my second floor (can anyone explain why my second floor is shorter than the first). I have pictures attached. In terms of complexity can the addition be suspended on its own footings(post and beam) In other words a 2nd floor freestanding deck with a roof. 2 Post and beam front and back and adjacent to the existing structure. Close enough that it can be attached without needing to be reinforced by the existing structure. Also by adding new footings I can suspend the room (a 2-3 foot hang on a drop beam) to gain more room. Every contracter and architect says to me with old homes you don’t know what you will run into when you open up walls. I agree but by suspending it on their own their is a lot less complexity with reinforcing with a century old structure. Has no one mentioned this possibility because it’s impossible or is is never done this way. My thought is I’m only adding a room, this way I’m building a deck with a roof. Besides blueprints and permits the actual build is a lot easier than a traditional addition with foundation.
