These projects always vary in complexity. We have done a number of these now using strong materials which are treated to last in the marine environment. These designs generally start with an initial idea and then evolve as the project progresses towards the final design. If you are interested in any marine based construction we would need to know the strength of any underwater footings or banks so that we can advise on the process we will use to complete the work. We use treated wood for the structural aspects of these projects and can advise on any floating walkways or similar materials needed to complete the project.
