QuoteSplit the gap between both ends, i.e. both end bays will be 3/4" narrower. Think in terms of your sheathing and making sure there is a stud at 4' intervals to support the edges. Usually you would put an extra stud or blocking at the corners to support the drywall edge and exterior corner boards so the end bays end up being several inches narrower.
QuoteFor the width question, it's just cheaper to trim off the joists than to buy another sheet of ply and rip 3" strips to fill that extra gap. If you were building on a continuous concrete foundation and wanted to rent forms or contract out the work, you'd probably find that those extra 3 inches would be relatively expensive because reusable forms come in 24" increments. I don't think the loft joists are an issue. If they were intended to rest on a let-in ledger then you could always use hangers instead but it might be cheaper to just cut down 16 footers. So it really comes down to deciding what you're going to cut and trying to minimize waste.
QuoteIf you hook your tape on the start of the board then place joists on 16 inch centers the difference is made up as you start the first board even with the end then the rest on centers. Think that way in drawing too.
