I have a pergola walkway planned that drops 140mm over 9m to fall in line with the slope of the garden. There are 5 posts (per side) over the 9m with brick plinths built around the base.
What's the best advice in dealing with the slope?
1. Should the entire structure be sloped parallel to the ground?
2. Should the brick plinths decrease in height to match the ground and the top beams be level?
3. Should the brick plinths be level with the beams and just the paving & brick edges fall with the ground level?
