How to Join Stud Walls at Angles

When making a corner or angle with stud walls, you need to maintain the structural integrity of the wall while also providing solid surfaces for exterior siding and interior drywall. Particularly on the inside of the corner, this requires strategic placement of studs so that there is a stud present on both faces of the interior corner. If you don't do this, when the time comes to install the interior drywall, you'll have nothing to attach it to at the edge.

  Lay out the studs in both sections of the wall to provide a nailing surface on the inside face. If you are butting a 3 1/2-inch-thick wall against the face of another wall at its end, install a stud so that its edges fall at 3 1/2 to 5 inches from the end of the wall. This stud will serve as the nailing surface for the edge of the drywall on that wall.

  Secure the two walls by nailing them together. Assume that the wall that extends all the way to the corner is wall No. 1 and the wall that butts into it is wall No. 2. Drive nails through the end stud of wall No. 2 so they are driven into the studs of wall No. 1. This secures the walls together and makes them both much sturdier.

  Apply exterior sheathing onto wall No. 2 first, so that it extends over the end of wall No. 1. This helps to further bind the two walls together. When you apply sheathing to wall No. 1, line up its edge with the face of the sheathing on wall No. 2.
