I want to move 2 gate posts closer to the outside kerb but don't know how deep they should be sunk into the ground. At present the gate is about 16' in from the kerb and actually makes it difficult to park more than 5 cars when we have visitors.
The present posts are 6" x 6" hardwood, (possibly mahogany or maybe oak, not really sure), and they support a 11' wide 5 bar gate. The vertical support rails of the gate are 5" x 3" and the gate height is 48" The current support posts stand 56" above ground and are concreted in but I don't know how deep they are. I have to replace with wood as it is to be kept in context with the house, (a country cottage), so concrete posts are not an option.
Can anyone give any suggestions how deep they need to be below the concrete drive?
