I live on a private road. At the bottom of the road was an industrial building that the residents gave permission to be installed 30 years ago providing it was only a fire door for a commercial building. The building was converted by permitted development to a residential property. The developer is now claiming he can still use the door and has an easement over the private road. We have enough evidence to challenge his easement claims but does a fire exit for a commercial building transfer to 2 story residential house. The front door for the building is via the high street that runs along the bottom of the private road.

This is a property & land law issue & not one for which this forum can answer. All I can say from my experience is that not all easements, deeds of variations and licenses for access for escape are permanent and some can be invalidated in various ways (e.g. one named party sells up) so you need expert sector specific advice
