A party wall notice is a legal document that’s often overlooked but vitally important in construction or renovation projects involving shared and/or adjoining walls between two properties.
The Party Wall Act 1996, a piece of legislation specific to England and Wales, provides a framework for preventing and resolving disputes concerning party walls, boundary walls, and excavations near neighbouring buildings.
Understanding the act can be complex, which may be why it is often overlooked entirely, and this guide aims to unravel the act’s complexities to help homeowners, contractors, and other interested parties navigate the landscape of party wall notices.
What is a Party Wall?
Before we dive into party wall notices, we first need to understand what a party wall even is.
A party wall stands on the land of two (or more) owners and forms part of a building. This wall can be part of one building only or separate buildings belonging to different owners.
For example, in a terraced or semi-detached house, the wall dividing the houses is a party wall. The floors/ceilings between flats can also be considered a party wall.
When is a Party Wall Notice Required?
A party wall notice is required when:
- You plan to carry out work on an existing wall, floor, or boundary shared with another property.
- You are building on or at the boundary with another property.
- You are excavating near a neighbouring building or structure.
Such works include, but are not limited to, loft conversions, basement excavations, extensions, underpinning, or any structural works affecting a party wall.
What are the Types of Party Wall Notices?
There are three types of party wall notices, which we’ll look at in detail below.
1. Party Structure Notice
If you intend to alter a party wall, floor, partition, or other structure shared with another property, you must serve a party structure notice.
For example, this may be necessary if you plan to cut into a wall to take the bearing of a beam or to insert a damp proof course.
Let’s say you live in a semi-detached house and you’re planning a loft conversion. This conversion involves strengthening the party wall to support the new structure. In this case, as the work involves alterations to an existing party wall, you’ll need to serve a Party Structure Notice to your adjoining neighbour.
2. Line of Junction Notice
A Line of Junction Notice is a type of party wall notice that relates specifically to construction along the boundary between two properties.
The purpose of this notice is to inform the neighbouring property owner(s) about the intention to build on or at the boundary. The notice is intended to protect both parties’ rights. It provides the neighbouring property owner with an opportunity to dispute the proposed work or agree under what conditions the work may proceed before any work is carried out.
For example, suppose you own a property and want to build an extension along the boundary of your property. This extension’s wall will sit exactly on the boundary line and will not extend to your neighbour’s land. However, it may affect your neighbour’s ability to build an equivalent extension in the future, because they won’t be able to use the wall you’ve erected without your permission.
In this situation, you need to serve a Line of Junction Notice.
The notice would inform your neighbour of your intention to build the extension wall on the boundary line. It should include all the necessary details about the proposed work and provide them with at least a month to consider the implications and respond.
3. Notice of Adjacent Excavation
If you plan to excavate within 3 or 6 metres of a neighbouring property, and your excavation work will go deeper than their foundations, you must serve a notice of adjacent excavation.
Imagine that you’re planning to build a new basement extension in your house. The work involves excavating the ground, and this excavation will occur within 3 metres of your neighbour’s property and will be deeper than their property’s foundations. In this situation, you’ll need to serve a Notice of Adjacent Excavation to your neighbouring property owner and give them ample time to respond before starting any work.
How to Serve a Party Wall Notice?
To serve a party wall notice, you should:
- Identify the affected neighbour(s): You must provide notices to all adjoining homeowners. This includes both freeholders and leaseholders.
- Prepare the Notice: You can prepare the notice yourself or hire a party wall surveyor or solicitor to help. The notice must include your name and address, a full description of the proposed work (with plans where necessary), and the proposed start date.
- Serve the Notice: The notice can be delivered in person or sent by mail. For obvious reasons, it’s recommended to use recorded delivery or have an independent witness to the delivery.
- Wait for the Response: Adjoining owners have 14 days to respond to a notice. If they agree in writing within that time, the work can proceed. If they dissent or do not respond, then a dispute has arisen, and surveyors must be appointed to determine how the works should proceed.
What Happens if a Party Wall Notice is Disputed?
If a notice is disputed, both owners are required to appoint an agreed party wall surveyor or each appoint a separate surveyor to prepare a “Party Wall Award”.
The award will set out the details of the work, how and when it can be carried out, and stipulates any additional measures for prevention of damage. Any costs associated with drawing up the award and a surveyor’s time will usually be met by the building owner since they are the ones who instigated the party wall process.
Conclusion
Understanding and implementing the Party Wall Act is crucial for those planning any construction work that could affect a shared wall. Neglecting to observe these legal requirements can result in the work being unlawful, leading to a potential lawsuit from affected neighbours.
It is strongly recommended that homeowners seek expert advice from chartered surveyors or solicitors experienced in party wall matters to ensure compliance with the law and to keep the construction or renovation process smooth and conflict-free.
