Sides that slope to the back
Stand a side on each end of the floor, from 18 mm exterior plywood: 600 deep and 1100 high at the front, its top cut to slope down 106 to the back, so the rain runs off behind.

Where it goes
The boards
Every size in millimetres. Bearers 50 × 75, floor boards 120 × 28, sides and roof from 18 mm exterior plywood, slats 100 × 22.
Left side
1100 × 600 × 18600 deep, 1100 high at the front and 994 at the back, 18 thick.
On the floor at the left end, from the front to the back.
Right side
1100 × 600 × 18The same as the left side: 1100 at the front, 994 at the back.
On the floor at the right end, from the front to the back.
Stuck?Show a hint
The top drops 106 over the 600 depth: a slope of 10°, enough for the rain to run off the back of the roof. A line across a face splits it, and pushing one piece as deep as the board is thick cuts it off.
