    Hi All,

    I live in a detached property and have just got planning permission for a single storey rear and side extension.

    Along the side of my land that is currently garden space where the side extension will go, we have fences that define the boundary between the side of my land and the bottom of 2 of my neighbour's gardens.

    To have the maximum space available for my extension, I would like to replace the existing boundary fences with what will be the side wall of my new extension. This also avoids creating a tiny gap between my new side wall and the existing fence which could not be accessed and would be difficult to maintain.

    I've seen lots of things posted saying that I'm allowed to build up to the boundary line but even if this is true, I'm not sure whether that means I'm allowed to build up to the existing fence or whether I can replace the fence with my new wall to use as a boundary instead. To be clear, there will be no guttering etc overhanging into the neighbour's gardens as the plan is to have valleys in the new roof so it all stays on my side.

    Any advice appreciated.

    Thanks

    You have planning permission, so you need to build to the approved plan, or submit another if you want to shift walls.

    Thanks for your reply although I'm not sure its helped me too much. The building regs plans do not mention how far up to the boundary I can build or tell me whether I can replace the fence with my new wall.

    In general, does anyone know what you are allowed to do in this instance?
     
  5. You should build to the approved planning drawings etc as stated above , and the building regulations drawings should correspond with the planning drawings.

    They wont. The planning permission plans will.

    Does that help?

    Hi both,

    Yes it does. Thank you. I've checked them out and called the planning officer and there is indeed a tiny less than 1mm gap between the new wall and fence which would equate to around 5" so this has answered my question. Thank you for your help!
