I need a little advice please, i'm doing a loft conversion soon and i need to know if the joists need bolting together on the overlaps in the center, and also the the new stairs that are going in are of a return type, and are going above the original ones, all the clearence's are ok do i just screw them to the walls or will it be better to sit them on some joists across the walls, the original stairs run up the center of the house.
thanks bill
