Okay, need some help... thoughts on mounting?

Okay, keep the randy jokes to yourself.  I mean the mounting of the chateau!

So... do I center mount it (as seen at right) with about 3 inches all around?  Bad side... harder to run a road right up to the edge.  Or do I offset a bit so you CAN run a road right up to the gate?  I would then have a bit of space on two sides I could fill in with a garden or something similar.
