It's not an offence, per se, (or contravention', in those areas where parking enforcement has passed from the police to the local authority) to park on the pavement anywhere outside of London.
It's only an offence to obstruct a public footpath (which, from your post, it seems unlikely that you'd actually be doing).
So I can't see why you'd have any problems.
However there are always a few awkward neighbours, aren't there?
