Do I Need Planning Permission.co.uk
Making the most of your Home

Hi all,

I have a question in regards to how it's best to represent a Party Wall for a ground floor extension. The property is in conservation area. We are still to discuss with the neighbours about Party Walls and if they will be happy to share the wall, by building it on the boundary (half and half). To speed things up though, we are planning on showing the wall completely on our side on the planning drawings. If, once permission is received, the neighbour agrees to share the wall, would this mean we are not building according to the planning permission and are we at risk of being enforced? Thank you!

If you secure approval for a wall that is proposed on your side of the boundary, then that is what should be built. Building something that deviates from the approval is in breach of Planning. Whether the LPA would take enforcement action is another thing.

Your best bet would be to submit a revised application for the wall centered on the boundary line. You would have to serve notice on those owners via Certificate B and Notice 1.
