Step 4 – The nominated expert awards a Party Wall Award that determines what work can be done, how and when it can be done. You will take lots of photos of the property and evaluate the property before and after the work is completed. We did not even see a copy of the drawings, and they were moved by our planning permission, which we won on appeal anyway. They need a planning permit, because they have consumed all the space below the approved development, although it was a little strange to ask us to sign something if we don`t know the total impact on our property. With our construction work, we will clarify a party wall agreement sooner rather than later, we don`t even have a client! Anyway, I would ask to see the plans – if not, how can you make an informed decision? You should then realize the impact of the work on your home. If the work does not damage your property, you can always object if an application for construction is filed with the Council. But the agreement is a matter of private law and I do not think you can revoke your consent if an expert believes that the work would not cause damage to your property. I think so. Remember that construction can only begin two months and one day after receiving written permission or agreement of your price. In case of excavation, it is reduced to one month and one day. .
