This is part of our 60 second read series of articles!

The Party Wall etc. Act 1996 applies to specific construction works that may impact shared walls or nearby structures. If your project involves any of the following, Party Wall procedures must be followed:

Internal Works

  • Chimney Breast Removal – Cutting away or supporting chimney breasts attached to party walls.
  • Wall Removals – Removing walls tied into a party wall, often for open-plan layouts.
  • Internal Excavations – Needed for new ground beams or pad foundations.

Loft Conversions

Loft works typically require Party Wall procedures for two reasons:

  • Removing roof coverings (which exposes the party wall)
  • Inserting steel beams into the party wall.

Extensions

Side, rear, or front extensions often trigger the Act due to:

  • Excavations for new foundations
  • Walls built on or near boundaries

Basement Conversions

Deep excavation and underpinning works near or under a party wall always fall within the Act’s remit.

New Walls

Whether building up to or astride a boundary line, Party Wall Notices must be served.

Other Works

Less obvious notifiable works include:

  • Changing roof coverings
  • Removing structures attached to a party wall
  • Removing chimney stack

All of these works give rise to the need for Party Wall Notice to be served and for the following Party Wall procedures to be followed.
