I'd like to finish the ceiling in this detached garage with insulation/drywall. I've attached some pictures but I definitely don't think there are enough (rafters/joists not sure which one?) to support strapping for drywall.
My plan right now is to add a couple more of these similar joists near the front of the garage by the door so that there are enough to support 1x3 strapping. I don't know how to go about doing it because it's a 24ft garage and I'm not sure how I would get wood that long to my house. Is there a way to join smaller pieces together for something like this?
Let me know if this sounds possible or if there's something else I should be doing. I've attached some pictures (please ignore the mess it's a WIP).
