Neighbours are planning a huge rear extension which will impact our property. They'd like us to agree to a shared surveyor to reduce their costs. We would prefer to have an independent surveyor. I know that professor surveyors are neutral but we are opposing their build and don't see any benefit to us in sharing, only the risk that the surveyor won't be truly impartial (even if we get to pick the surveyor). Neighbours are new and I'm not imagining there will be great relations after the build. We're upset about the extent of their build and impact it will have on us. Also because they didn't tell us about their plans. We found out when the council sent us a letter. They only approached us after the deadline for objecting to the plans had passed, a good few weeks after they submitted their plans. The Third Party Wall Notice was then popped through the letter box followed up by a text asking us of we can sign asap as they'd like to start their build. They don't have planning permission yet from the council but I assume they are confident they'll get it. We have objected to the council but haven't heard back and aren't optimistic about our objections being upheld.
Can anyone advise on whether we should concede to reducing their costs by sharing a surveyor? We genuinely don't see any benefits. We also think that they're only being "nice" so they can get the build underway and because they've already asked for access to our property to build their extension. They also want to remove our garden fence to do so.
We are really unhappy with the proposed build. It really is huge and will dramatically change our enjoyment of our home as it will loom over us. Being pragmatic, we think planning permission will be granted so it's a case of mitigating the impact/damage to our property and making sure we're covered where they rip down our fence etc. Hence why we wanted an independent surveyor only the neighbours really what to share ours. We still have to live next to them so don't want to piss them off even though they've clearly shown disregard for us!
Any advice would be much appreciated.
