My very limited experience of flying in Spain is that they can be a bit precious about airport security and planning issues - but that once airborne, things should be quite straightforward. But definitely - it is tbe local planning experience that you need to tap into there.
As it happens, a few years ago my brother restored an old farmhouse in Asturias - he found hiring local planning expertise absolutely essential to success in that also.
