Party Wall Issues When Demolishing an Attached Garage or Outbuilding

Demolishing a garage or outbuilding may appear straightforward.

But if the structure is physically connected to a neighbouring property or shares a wall at the boundary, the Party Wall position should be checked before demolition starts.

Is the wall shared?

The first question is whether the wall between the structures is actually a party wall or party fence wall.

Its legal status depends on its position and how the buildings use it.

Our guide explaining what a Party Wall is under the Act provides further guidance.

Demolishing part of a party structure

Section 2 of the Party Wall etc. Act 1996 provides rights relating to certain works to party structures, including demolition and rebuilding in particular circumstances.

Where demolition affects a shared wall, notice may be required.

See our Section 2 Party Wall guide.

What happens to the exposed wall?

Removing your building may expose a wall that was previously internal or protected from the weather.

The project may therefore need to address:

  • weatherproofing;
  • roofing junctions;
  • flashings;
  • exposed brickwork;
  • structural stability; and
  • making good.

These details should be considered before demolition rather than afterwards.

Is another building replacing it?

If the garage is being demolished to make way for an extension, the new foundations and boundary walls may create additional notices under Sections 1 or 6.

It is usually more efficient to consider the demolition and replacement scheme together.
