Responding to William across at 1000Huts.
See my planning application, references across in 1000Huts. My advice: keep it small, 1m each way bigger than your hut.
Other people commented on parked. No requirement in legislation to provide parking nor footpaths / trails to a hut. If you are requested to do so simply refuse. You may wish to include a photo of your bicycle / horse / rickshaw / helicopter / nearest train station / walking boots. If they will not Validate your application unless you enlarge site or add parking or UFO landing site request statement of which law requires this before Validation (Validation is simply a properly submitted application and request for parking to be added is pre-judging the application).
