Our neighbours (the side of their house is the back of our garden, and their garden runs along side our driveway) are looking to put an extension on the end of their house and are requesting access to our garden and drive to do this. This would mean removing part of our fencing will the work is going on - which would be quite a while apparently. I have attached a paint sketch of the lay out - we have no gate/fence on our drive to the road, but the garden is separated from the drive by a fence - this is the fence they would want to remove to carry out the work.
My problem is we have two young children (2 and 3 yrs) who use the garden daily to play in and this would obviously make it unsafe as it would mean the garden perimeter would not be secure whilst the work is being carried out. i.e. there would be easy access to the road from our garden/drive, and to the area the work is being carried out in. Would I be justified in denying access/permission on these grounds or would they have to ensure that our garden is secure from the works/road whilst the fence is down and they are carrying out work??
I don't really know much about this or where I stand in regards to it all. Please help.
