Home Extension: Have You Consulted a Party Wall Surveyor in London?

Aside from the basic floor plan, you might also be required to submit specific details like plumbing and electrical plans. Make these ready upon request to make the process easier for both of you. The opposite party may be more inclined to agree if they are aware of the specifics, so be willing to sit down with them and explain what you want to do and how they might be affected. If you have already consulted a party wall surveyor, explain his findings to your neighbour and how both of you are affected by the Party Wall Act. Finally, if any major changes in the plan are made, particularly as regards the project’s time frame, be sure to inform all other involved parties and send them a revised plan immediately.

Planning a Project? You Might Need a Party Wall Surveyor in London

Planning some home improvement project? Why would you need a party wall surveyor in London? A party wall surveyor is important in situations covered by the Party Wall etc. Act. There are several situations that this Act deals with: where there is an owner on each side of a shared wall, where a property owner plans to excavate near a building owned by another, or where there is an owner on each side of a boundary line marked by a fence or not marked at all. The Act lays down the correct procedures to follow when doing projects that fall under these definitions. If you fail to follow these procedures, you could find yourself liable for delays and additional costs.
