Our Services


The Party Wall etc. Act 1996 deals with party structures and other works too. The Act covers some excavation works (such as underpinning or new foundations near an adjoining Owner’s building) and building walls, extensions or new buildings on or near a boundary. We are appointed by Building Owners (wishing to carry out such works) their neighbours (referred to as Adjoining Owners) or both parties as Agreed Surveyor.

As well as preparing schedules of condition and Party Wall Awards and agreements for works, we advise on rights and obligations and settle (or arbitrate on) matters if damage is caused.

Note: the rights and obligations of an owner include those with an interest in a property such as tenants and leaseholders with more than a one-year tenancy.

Three main types of work are covered by the Party Wall etc. Act 1996:

  • Section 1. Building on the Line of Junction. This covers building work on or near the infinitely fine boundary line. If it is proposed to construct a building or a wall, the Act may apply.
  • Section 2 of the Act. Party Structures. This includes Party Walls between buildings, floors between flats and Party Fence Walls (shared boundary walls) between different plots of land; see Party Walls and Party Structures. Works covered are listed in section 2.(2) of the Act. For example, cutting into a party wall for beam ends, damp-proof course, etc., raising the height of it for a loft conversion, repairing or rebuilding a party structure, replacing the floorboards or ceiling and/or adding sound insulation, connecting an extension to the wall, cutting off chimney breasts or other features connected to the wall, exposing the party wall to the weather, etc. Where there are two structurally separate buildings, connecting a flashing or weather-proofing between them is covered by the Act.
  • Section 6 of the Act. Adjacent Excavation and Construction. This applies where excavation for new foundations, underpinning, basement extensions and car parks, etc. are planned to go below the level of an adjoining owner’s foundations and less than three metres (and on some occasions six metres) away. See Adjacent Excavation

Where the Party Wall etc. Act 1996 applies, the Building Owner needs to serve one or more notices on the Adjoining Owner; see Notices.

Awards and Agreements
Where the Party Wall etc. Act 1996 applies, the owners need to reach written agreement or have a formal Party Wall Award drawn up.

A Party Wall Award is a document which sets out what a Building Owner can and cannot do and how/when the work is to be carried out.

An Award usually includes a Schedule of Condition of the adjoining owner’s property, which helps to determine whether or not damage is caused by the works. But a schedule of condition often simply reassures a neighbour that minor normal cracks that they were not previously aware of have not been caused by the other neighbour’s building works.

The Act uses unhelpfully strong words such as dissent, dispute, and deemed dispute. But, experienced and commercial owners often choose to be in deemed dispute so that an Award can be promptly and amicably prepared, and ensuring that both sides' rights and obligations are clear.

Ash Chartered Building Surveyors carry out aerial photography using a camera mast and professional-grade, full-frame format high-resolution camera. Our 15 metre-high, tripod-mounted mast can work on sites that are inaccessible to vehicles and cherry-pickers. Camera masts can work in built-up areas where Civil Aviation Authority regulations make the use of drones illegal and unsafe. Our 36 megapixel images enable precision viewing of defects.
