Roof is currently being tiled, in the next couple of weeks I want to build a pair of softwood ?garage? doors.
Height is 2085 (82?) and width 3302 (130?) for the pair ..~ 1650 each
Been getting my original thoughts together ? as per this sketch:

an outer frame which is rebated to take a tongue & groove ?infill?, I would make my own t&g using full length loose tongue splines, all well glued to each other, and into outer frame. I would horizontal brace (on inside) at hinge handing points, and fit a diagonal strut between the braces for racking strength ? as per this pic:

initial thoughts on sizes of timber to use, and how to do it are in the drawing

interested in views on sizes of timbers, in particular the top/ bottom rails and the side stiles, joints etc.
Also not sure if cross brace should strut against horizontal support & verticals as shown, or horizontal only as I have seen in some carpentry books. See:

Also no real idea yet on how to joint in the horizontal braces ... seen dowels suggested in one book, other option I suppose could be a half lap joint ?
A couple of observations about the design, the inner splined panel can't be glued to the outer stiles, natural expansion and contraction would tear the doors apart.
Even though the bracing looks good in the drawings, I think they are much too close together to keep the doord from racking. You could build the doors and line the back with quarter inch plywood, that would keep them from ever sagging. This would also solve the problem of attaching the horizontal bracing as it would be mostly cosmetic.
