Required wood and alternative sizes
There are five different lumber sizes used in this project. They are:
90mm x 90mm (3 1/2″ x 3 1/2″) for the beam and the four corner uprights,
90mm x 45mm (1 1/2″ x 3 1/2″) for the ladder upright,
70mm x 45mm (1 1/2″ x 2 1/2″) for the frame,
45mm x 45mm (1 1/2″ x 1 1/2″) for the ladder rungs,
and 150mm x 25mm (1″ x 6″) for the roof, walls, and floor
There is also 1 sheet of exterior 18mm x 2400 x 1200mm (48″ x 96″ x 3/4″) plywood required.
All the lumber used in this project is surfaced (dressed, planed) except for the 150mm x 25mm (1″ x 6″), which is rough.
If 70mm x 45mm (1 1/2″ x 2 1/2″) is unavailable in your area, you can rip 140mm x 45mm (1 1/2″ x 5 1/2″) stock in half.
Or alternatively you can use 90mm x 45mm (1 1/2″ x 3 1/2″) stock
If 45mm x 45mm (1 1/2″ x 1 1/2″) is unavailable in your area, you can rip 90mm x 45mm (1 1/2″ x 3 1/2″) stock in half.
If 150mm x 25mm (1″ x 6″) is unavailable in your area, then use the closest size that is available, maybe even decking boards.
If other size lumber is used, or if unsurfaced (rough) frame lumber is used, you will need to make some adjustments to the measurement of the plans to compensate for the size difference.
In all, you will need the following amounts of wood…
Measurements are given in millimeters and (inches). All stock should be suitable for outside use.
90mm x 90mm (3 1/2″ x 3 1/2″) surfaced/dressed stock, 5 @ 2400mm (96″)
70mm x 45mm (1 1/2″ x 2 1/2″) surfaced/dressed stock, 40 meters (132 ft)
90mm x 45mm (1 1/2″ x 3 1/2″) surfaced/dressed stock, 1 @ 2000mm (80″)
45mm x 45mm (1 1/2x 1 1/2) surfaced/dressed stock, 6 meters (20ft)
150mm x 25mm (1″ x 6″) rough unsurfaced stock, 95 meters (310ft)
1 only sheet 18mm x 2400mm x 1200mm ( 4ft x 8ft x 3/4″) exterior plywood
