Building Rocks slightly - Best way to reinforce / Window Door placement

Hey folks, I'm not sure if anyone here has the knowledge to assist me but I'm not sure where else to ask. I'm remodeling an old chicken house into a guest house and once I removed the old asbestos siding the building started to sway slightly when I was on the roof. We assume the sway will be corrected when siding is put back on the building, however, this raises concerns for window and door placement. The building is small ( 18' x 22' ) and has an offset gable roof. I would like to put an 8' wide sliding glass door on the west side but this will mean less siding to reinforce the building.


This screenshot is the original design for window and door placement.

This screenshot is what we are thinking would be a better option to maintain stability of the structure- but i hate it

And here is a photo of the structure as it is now.

Does anyone know of a good way to reinforce the building while much of the west side is cut out for doors and windows? Would these door and window placements render the structure unsafe?

Thank you!

To be clear, the unsafety you are pointing to comes specifically from the lack of corner bracing? Is it your opinion that,with added corner bracing, having 1/3 to 1/2 of the area of the westernmost wall open for doors and windows, the building will be stable?

I plan on replacing the existing rafter ties with more attractive and sturdier lumber. Adding more of them won't be a challenge, however, the bed is lofted on the opposite end so I plan to use the joists of the loft itself as extra building bracing and having rafter ties like so.

Sheet the exterior, that will take care of shear. In the meantime if you want to open up walls for doors/windows, add temporary bracing. Being an old structure, you may want to plumb it up before bracing it in place, then add your exterior sheathing. On a smaller building like this we've used chain falls or come-alongs to square it up before re-sheeting it.

Okay, so we keep coming back to sheeting the exterior, however, if the bottom 8 feet of the west side is opened for a door and window the sheetable surface area is greatly diminished. Do we think the upper half is enough?

Thank you everyone for your responses.

You may end up with a portal wall situation by opening up much of the west wall. Headers would need/should run to each corner wall. Sheething is best bet for sheer on the walls themselves then. Location and local wind loads will dictate your needs.

Are you a contractor? These are simple questions and not very complicated.

Most skilled contractors would have a decent solution and would just need a bit of help making sure they were doing enough to make it solid.

Sheet inside and outside with plywood. Blocking, sheet the roof, add solid headers, angled bracing from corner to corner and the other suggestions folks here have given you and it will be very solid.

All of that or some of it. That is what contractors do and learn.

However, just realize, we aren't there, we can't see everything, we don't know the requirements in your area, weather, wind loads and have no responsibility for your actions and take no liability for what you end up with. We are just friendly guys who are chatting about stuff.
