Hi there,
We have been granted the planning permission for our ground floor flat. however, the challenge is that the upstairs neighbour who has a small terrace over my roof has been very difficult. The terrace (probably 2sqm, has enough space for 2 small chair and a coffee table but no space to walk around) has some incorrect decking which is not appropriate for a terrace and could potentially damage the roof, the condition of the terrace is truly below average. However, the owner of the flat above has said that it's an important aspect of the flat which he would like to sell in the future and my build might devalue his flat, impact his view.
In order to build the extension, even with the legal approval, we still need his permission to safely remove and rebuild the terrace as part of the extension. He has been quite difficult and very slow to response to my request. Since the council objected to the terrace extension, he also asked for deed of easement to my extended roof which we have told him to proceed, I think he realised it would cost him money so he stopped the topic. His typical response is if always along the line of "if I'm not happy with proposal , I won't agree" but without actually telling me what he wanted, he wanted me to propose something that he will be happy with. He also opted to go appointed his own partywall surveyor because he was worried the extension will devalue his flat (which overlook our garden and has been empty for over a year, unkept). we have a very competent architect and have paid a lot for that, the design is very good and will be a huge improvement compare to the current outlook. The replacement terrace will also cost us 3k to build (on top of the x amount on his party wall surveyor).
I feel like we have no choice but keep on trying to get his agreement and wait in despair even though I have the permission to extend and he has no power to stop it (he would if he could).
Is there anything legally we can do? I assume if we proceed with the removal of my roof which will we have the right to but in effect it will damage his terrace or worse collapse it then he can sue us?
Many thanks
