I asked the question if the Piplings purchased the house for the specific purpose of opening a nursery and if so I would have expected their solictor to have advised them of the restrictions.

I didn't get an answer, so I presume they knew full well that they would have to challenge some existing laws and get the neighbours on side.

It's curious that the council had 27 objections to the change of use from a residential property to a nursey and only 1 in favour when the application was put in last year. Yet the permission was still granted. Therefore be thankful that these covenents are in place. It could be a hotel or a wine bar next time and it could be next door to you.
