Introduction and lumber requirements
This arbor is a solid construction consisting of 100x100 (4x4) posts concreted into the ground, 100x50 (2x4) rafters and 50x50 (2x2) laths.
The overall height is 2200mm (88") although that can be changed to suit, and the footprint (overall area on the ground) is 1100mm (44") x 700mm (28").

The pitch (angle, slope) of the rafters (off horizontal) is 18.4°.
That is: a rise of 1 in 3 (or 1/3) which means that the rafters rise 1 unit of measurement for every 3 units of measurement along the horizontal plane (run).
In the United States the pitch is given in inches, with the run (horizontal plane) being 12 inches and the rise being a ratio of that. In this case, the slope of the rafters would be given as 4" of rise over 12" of run, which is still the same thing as a rise of 1 in 3 or 18.4°.

Note: There is another similar plan with a 45° top if you prefer a steeper roof. To see click here

Lumber requirements
Use lumber suitable for exterior use. Either smooth (dressed, surfaced) or rough wood can be used. It is just a matter of personal preference.

You will need....
4 of: 100mm x 100mm (4"x4") posts 2400mm (8ft) long.
2 of: 100mm x 100mm (4"x4") beams 1000mm (40") long.
2 of: 100mm x 100mm (4"x4") blocks 500mm (20") long.
3 of: 75mm x 25mm (1"x3") rafter braces 600mm (24") long.
6 of: 100mm x 50m (2"x4") rafters 900mm (36") long.
14 of: 50mm x 50mm (2"x2") laths 1000mm (40") long.
16.5m (55ft) of 25mm x 25mm (1"x1") square stop to hold the lattice panel in.
