Step 4. The walls
Cut all the required battens slightly over length. The ends can be cut off after they have been nailed (or screwed) to the plywood wall panels. Cut all the vertical and raking wall battens with a 45 degree angle at the top end. The raking wall battens are of 100mm x 25mm (1" x 4") stock and the vertical (upright) battens are of 50mm x 25mm (1" x 2") stock.
Lay the perimeter battens on a flat surface (such as the cottage floor) under the middle (larger) plywood panel, so that the top raking battens are flush (even) with the top rake of the plywood panel and the side battens are half under the plywood panel sides. Refer drawings c, d, e in The Plans section.
Nail or screw the plywood to the battens at 150mm (6") intervals.
Add the two smaller side plywood panels as per drawings c, d, e in The Plans section.
ALSO TAKE NOTE: The vertical batten is flush (even) with the plywood at one end of the wall, but at the other end the batten projects past the plywood by 35mm (1 3/8") which is the thickness of a batten plus the plywood. This is the same with all four walls. Refer drawing g and drawing g2 in the Plans section for clarity.
Step 5. The walls (cont'd)
When the plywood panels have been nailed or screwed to the perimeter battens and the battens under the joins, the overhanging ends of the battens can then be cut off (see the two pictures on the right).
