It would all depend on how sure he is or isn't that a building will be appearing there in the future and what he's willing to pay for "future proofing".
If he's pretty sure then a big pipe, some goodly sized conductors, possibly a xformer. and a small sub panel might be in order to just get it done now.
If not sure but maybe it will happen I would at least oversize the pipe to accommodate a larger pull in the future.
