Party Wall Guidance

What is a Party Wall or Party Structure?

Is my work affected by the Party Wall etc. Act?

You must find out and check  whether your work is covered by the Party Wall Act.  Your local building control and planning departments will not tell you, you might want to check with your architect or designer.

If you intend to carry out building work in one of the following categories you must correctly notify all affected neighbours by sending a Party Wall Notice:

  • Work on an existing wall or structure shared with another property.
  • Building a free-standing wall of a building up to or astride the boundary line.
  • Excavating near a neighbouring building

What is a Party Wall or structure?

Party Walls or Party Structures are defined as one of the below:

  • A wall that ‘straddles’ the boundary line between two premises is a party wall, even if it has not been built against and does not form a part of the neighbour’s building.
  • A wall that divides two premises and forms a part of the structure of both is a party wall. This applies even if only part of the wall forms a part of the structure.
  • A flank wall of a building that has been built against is a party wall to the extent that both premises use it. This means part of the wall can be a party wall and part might not be. This is the case even if the enclosure was done after the building was originally built.
  • A garden wall straddling the boundary is called a Party Fence Wall — repair costs will be shared under the Act.
  • Other parts of a building may be party structures and need similar process and notices — for instance the floor between two flats is a party structure.
