I don't know what you mean by "bulk out one side of the wall".
I have made a sliding door that fits entirely within the wall. At the
door opening I have two vertical pieces of 1½" angle steel with
horizontal pieces of 4"x1" screwed to them, to attach the wallboard to
on each side. The rollers and track are commercially available.
