Step 1. Mark and cut
Mark and cut all the plywood panels, both wall and roof, to the shape and dimensions as shown in drawing a and drawing b in The Plans section.
Cut the floor frame members as per drawing f in The Plans section.
Cut the floorboards: 16 @ 1590mm (63 5/8") out of 100mm x 25mm (1" x 4") stock. Also put aside 20m (65ft) of 100mm x 25mm (1" x 4") stock for the battens that go around the top of the walls, the roof beams, ridge capping, and valley boards.
The remainder of the 100m x 25mm (1" x 4") stock can then be cut in half lengthwise, making the 50m x 25mm (1" x 2') stock that will be used for the vertical battens and the door.
Step 2. The floor frame
On a flat surface, make up the floor frame consisting of four joists and two end members out of 100mm x 50mm (2" x 4") treated stock to the dimensions as shown in drawing f in The Plans section.
When the floor frame has been nailed together, it is then ready to be made square.
NOTE: The frame is square when the distances between the opposing diagonals are equal.
Step 3. The flooring
Commence nailing the 100mm x 25mm (1" x 4") floorboards to the floor frame, beginning flush with one end. Continue placing and nailing the rest of the boards tight against one another, until the floor is covered.
The last board will most likely need cutting lengthwise to finish even with the end of the floor frame.
