Thank you for your reply. The wording is as follows:
The owner and occupiers of Number 127 and all persons authorised by him or them respectively a right of way on foot only over and along and across the land coloured green.
The garden gate is right outside my kitchen window. The neighbour runs a day care centre and the extension will house the room in which she will run her day care. This means that from having them use the right of access twice per week, they will now be using it to gain access to their property many times a day. The questions are:
1. Are they allowed to use the access through my garden for their day care centre i.e. as a drop off and pick up entry?
2. They will now need to stop and unlock a door to enter the house - it is very dark in that corner, and a light would need to be installed for them to see the door in the dark - this would shine directly into my home.
3. If at any time I wanted to extend my home (which I understand would require my to have the access moved) I would not be able to as it would go over the door into their house.
