Storage Buildings II – Walls/Wall Framing
The walls are constructed just like the floors. You actually build them on their side on the floor of the shed. Use the precut studs (92 5/8") because by the time you add a single bottom plate and two top plates, the wall will be 97 1/8 inches high.
You must make sure these walls are square before you attach the plywood! I don't need to tell you the diagonals. Just measure them in the field after you nail the wall together. When the diagonals are equal, the wall is square. Nail the wall plywood so it overhangs the bottom of the wall by 1 and 3/4 inch. This will prevent rainwater from entering under the wall plate. Don't worry about the missing wall sheathing at the top.
Build the two 10 foot end walls first. When you frame for the door wall, let the bottom plate run from corner to corner. We will cut it out in a few days. Trim the edges of the wall plywood even with the ends of the walls.
For the door wall, create a rough opening that measures 8 feet wide and 7 feet tall from the subfloor. This will allow the metal overhead door to fit perfectly.
When these two walls are complete, stand them up and nail them in place. Be sure the overhanging wall plywood is tight against the floor system.
Framing the other two walls will be a little tougher. These have to be framed sideways since the two end walls are in place. Remember to let the wall plywood overhang the necessary 4 inches! These walls, don't forget, are not 12 feet long. The plates actually measure 11 feet 5 inches. The first two walls make up the difference. By allowing the plywood wall material to overhang, this allows you to nail the corners together when the walls are erected. Once the walls are erected, check the top corners of the wall for square. It should be the same diagonal as the floor if you did everything right.
