Follow your plan and revise it as needed. Measure and cut the walls, floor, and roof boards. To save problems later, be sure all cuts are square. Label each piece--otherwise it's easy to get a piece out of place. Trust me on this.



Brass screws don't rust, but they are soft so pilot holes are important. Drill them with two different bit sizes. Holes in the board you are passing through should be the same diameter as the screw shanks. Holes in the board that the screws are tightened into should be smaller than the screw threads. Temporarily assemble the pieces to ensure that everything fits correctly. Hint--place nails in the pilot holes or drive the screws just part way in.
