Relocate the storage house (bod)

Hi, we have a storage house (bod) that needs to be moved to another place in the garden. The bod size is 2. 4m x 1. 8m made by wood. In the new location, it need to setup the foundation for the bod. Today there is only mud. The distance is about 50m. We prefer to move it without disassembling it. From my eyes there are 3 possible ways (see pic). Point a might be the easiest but the road is too narrow for a car. Point b has 0. 5m vertical height which requires a lift. Point c has a 0. 5m fence so it also requires a lift. Of course if we have to disassemble and reassemble then it is not a problem, but guess it costs more? See picture for details. We speak English, and need the work to be done as soon as possible. Thanks, Feng
