Personally i'd install a path alongside the hedges to help with cleaning up cuttings (this is wha I'm planning in my garden).
Id then create borders against this path, so the path is hidden. Its a nice large garden so the borders could be quite deep, curved borders would look really nice.
Maybe have an oval shaped lawn, with deep curved borders around it. Im not a fan of having a mass of lawn with plants flung to the outside edge, but thats my personal choice.
