We have a quote from a builder to do our front drive and part of the work required will be to remove a retaining wall on the boundary and rebuild as it isn't doing its job and retaining. We are also seeking to have the chimney removed in our lounge which attaches to our neighbours.
The neighbours are happy for us to do the work. I think we will need a party structure notice for the chimney and a line of junction notice for the wall.
My question is this. My builders (who I have used before for a much larger build so know I can trust them) have said that the have a gap to do this in 2 weeks time. Can my neighbours give written consent for the work to start before 2 months have elapsed on the notice (1 month for line of junction) or are the time periods inviolable?
Thanks
