Party Structure Notice Explained: Section 2 of the Party Wall Act
If you are planning building works that affect a shared wall, floor, or other party structure, you may be legally required to serve a Party Wall Notice under Section 2 of the Party Wall etc. Act 1996.
Party Wall notices are most commonly required for loft conversions, structural alterations, chimney breast removals, and steel beam installations, but they are often misunderstood or overlooked — which can lead to disputes, delays, or injunctions.
This guide explains what a party structure notice is, when it is required, what it must contain, how neighbours can respond, and how disputes are resolved under the Act.
If you are unsure whether your works require a party structure notice, Graham Kinnear Property Consultants can advise and manage the process correctly from the outset.

What Is a Party Structure?
Under the Party Wall Act, a party structure includes more than just a shared wall. It can include:
- A wall forming part of a building and standing on land of different owners
- Floors or ceilings separating flats or maisonettes
- Shared walls between semi-detached or terraced houses
If a structure separates buildings or parts of buildings owned by different people, it is likely to be a party structure for the purposes of the Act.
What Is a Party Wall Notice?
A Party Wall Notice is the formal notice served under Section 2 of the Party Wall etc. Act 1996 when a building owner intends to carry out works that directly affect a party structure.
These works go beyond simple decoration and involve cutting into, altering, or structurally affecting the shared element.
The notice gives adjoining owners the opportunity to:
- Understand what works are proposed
- Consent to the works, or
- Dissent and trigger the appointment of surveyors
Common Works That Require a Party Wall Notice
A party structure notice is usually required for works such as:
- Cutting into a party wall to install steel beams
- Loft conversions involving structural alterations
- Removing chimney breasts attached to a party wall
- Raising, thickening, or underpinning a party wall
- Cutting away projections from a shared wall
- Altering floors or ceilings between flats
These works are all specifically covered by Section 2(2) of the Act.
When Must a Party Structure Notice Be Served?
A Party Wall Notice must be served:
- At least two months before the works are due to start
- On all adjoining owners affected by the works
The notice period is longer than for excavation notices because party structure works directly affect shared structural elements.
Party Wall Act reference: Section 3(1)
What Must a Party Structure Notice Include?
To be valid, a party structure notice must be in writing and clearly explain the proposed works.
It should include:
- The name and address of the building owner
- The address of the property where works are proposed
- A clear description of the works affecting the party structure
- The proposed start date (at least two months after service)
While drawings are not always legally required, including plans and structural details is strongly recommended, as this reduces misunderstanding and speeds up agreement.
How Can a Neighbour Respond to a Party Wall Notice?
Once a party structure notice has been served, the adjoining owner has 14 days to respond.
They may:
- Consent in writing, allowing works to proceed
- Consent subject to a Schedule of Condition of their property being undertaken
- Dissent and appoint a surveyor
- Do nothing, which is treated as dissent after 14 days
- Serve a Counter Notice
If dissent arises, a party wall dispute exists and must be resolved by surveyors under Section 10 of the Act.
What Happens If There Is a Dispute?
Where a dispute arises, either:
- One Agreed Surveyor is appointed, or
- Each owner appoints their own surveyor
The surveyor(s) will then produce a Party Wall Award, which regulates:
- How the works are carried out
- Safeguards to protect the adjoining property
- Access arrangements
- Responsibility for making good damage
- Allocation of surveyors’ fees
Your Responsibilities When Carrying Out Works
Although Section 2 grants rights to carry out works, it also imposes duties. You must:
- Avoid unnecessary inconvenience
- Carry out works with proper care and skill
- Make good any damage caused, or compensate for it
- Comply fully with the terms of the Party Wall Award
These duties apply whether or not damage actually occurs.
Access Rights for Party Structure Works
The Act provides rights of access to neighbouring land where reasonably necessary to carry out notifiable works.
Access must:
- Be during normal working hours (except in emergencies)
- Be preceded by proper notice
- Be exercised with care and minimal disruption
These rights are governed by Section 8 of the Act and are often regulated in the Party Wall Award.
Costs: Who Pays?
In most cases:
- The building owner pays the reasonable costs of the party wall process
- This includes surveyors’ fees and the cost of preparing the award
However, surveyors can apportion costs differently if the works benefit both owners or if specific circumstances justify it.
What Happens If You Don’t Serve a Party Wall Notice?
Proceeding without serving a required party structure notice can result in:
- Injunctions stopping the works
- Claims for damage or loss
- Increased project costs and delays
- Deterioration of neighbour relationships
Serving the correct notice at the correct time is one of the most effective ways to protect your project.
Step-by-Step: Getting a Party Structure Notice Right
- Confirm whether the wall, floor, or ceiling is a party structure
- Identify whether the proposed works fall under Section 2
- Prepare a clear written notice
- Serve the notice at least two months before works begin
- Manage the 14-day response period
- Appoint surveyors promptly if required
- Comply fully with any Party Wall Award
