As the pergola
is so large it has to be sturdy to ensure that it can survive high
winds. We used 4-by-4 inch timbers for the posts and 5-by-2 inch
timbers for the cross members. These are the proportions, which
from experience, I have found to work well. I have seen many pergolas
erected with 3-by-3 inch posts and they are far too flimsy.
You must take
care when you build close to an adjoining property. Don't use your
neighbour's wall as a support. This pergola was free standing with
the uprights set in concrete for stability and endurance.
