Building a retaining wall with a fence attached can be a tricky project.
What type of wall?
What type of fence?
Will the retaining wall require a council approval?
Will the combination of fence and retaining wall attract a relaxation?
These are all questions that need to be asked and answered before the project is started. Consider that there are many combinations of fence/retaining wall constructions. Not all are suited to every situation and all should be considered. If you are considering such a project make sure your contractor can quote more than one option i.e:-
-timber fence / concrete sleeper
-timber fence / timber sleeper
-colour bond fence / concrete sleeper
-colour bond fence / block wall
-powder coated aluminium / block wall
and so on.
Make sure the contractor you choose is licensed with the QBCC to perform the works. Make sure that the contractor is aware of the relevant legislation regarding the construction of fence/retaining wall constructions. If you do your homework you should end up with a successful project that will add value to your property for years to come.
