Hello mate,
I’m up in North Norfolk too although my yard is in Norwich. Have you tried Jack Richards at Fakenham? They may rent some space? Alternatively, there are a couple of places over in Melton Constable, Briston and there’s also a place at Hunworth, although I haven’t got numbers for them? The Hunworth place is right next to Thaxters Timber so they may be able to give you some info.
Good luck. Paul
