How Early Should You Start the Party Wall Process Before Building Work?
Planning an extension, loft conversion or major renovation involves many different stages. Homeowners often focus first on architectural drawings, planning permission, Building Regulations and finding a reliable contractor. However, if the proposed work falls within the scope of the Party Wall etc. Act 1996, the party wall process should also be considered well before construction is due to begin.
Leaving party wall matters until the last minute can create unnecessary pressure on a building project. Your neighbour needs an opportunity to consider any notice they receive, and if a dispute arises under the Act, surveyors may need time to review drawings, inspect properties and agree the necessary documentation.
Starting early gives everyone involved more time to deal with the process properly.
At Adam Joseph Chartered Surveyors, we help building owners and adjoining owners understand their responsibilities and navigate party wall procedures with clear, practical guidance.
When Should Party Wall Matters Be Considered?
Ideally, you should consider the Party Wall etc. Act during the planning and design stage of your project rather than waiting until builders are ready to arrive on site.
At this stage, your architect or designer will normally have prepared enough information to understand the general nature of the proposed works.
Projects that may require closer consideration include:
- Loft conversions involving steel beams inserted into a shared wall
- Rear or side extensions
- Excavations for new foundations near neighbouring properties
- Basement construction or underpinning
- Removing chimney breasts from a party wall
- Raising or rebuilding a shared wall
- Building a new wall on or near a boundary
- Certain structural alterations affecting a party structure
Not every renovation project falls within the Act. However, checking early allows you to identify potential requirements before they affect your construction timetable.
Our guide answering 10 common questions about party wall issues provides further information for homeowners who are unsure how party wall procedures may affect their project.
Why Waiting Until Construction Is About to Start Can Be a Problem
One of the most common mistakes homeowners make is assuming that party wall matters can be dealt with immediately before building work starts.
The reality is that the process involves other property owners, which means the timetable is not entirely under the building owner's control.
Once a notice has been served, an adjoining owner must be given the appropriate opportunity to respond. Depending on the response, additional steps may then be necessary.
For example, if the adjoining owner consents, the process may remain relatively straightforward. However, if a dispute arises under the Act, surveyors may need to be appointed and a Party Wall Award may be required before the relevant work proceeds.
Starting the process early gives you a buffer within your project schedule.
Get Your Drawings Ready
Before approaching a Party Wall Surveyor, it is helpful to have relevant drawings and information about the proposed works available.
Depending on the project, these may include:
- Architectural plans
- Structural engineer's drawings
- Foundation details
- Sections showing excavation depth
- Construction method information
The surveyor can review the available information and consider which aspects of the proposed work may fall within the Act.
Having clear information at an early stage can also make it easier to explain the proposed project to neighbouring owners.
Talk to Your Neighbour Early
Formal party wall procedures are important, but good communication between neighbours can also make a major difference.
Where appropriate, consider discussing your plans with your neighbour before they receive a formal notice.
A neighbour who unexpectedly receives legal-looking documentation relating to major construction next door may understandably have questions or concerns.
Explaining what you are planning, when you hope to start and what steps you are taking to protect neighbouring property can help create a more constructive atmosphere.
Informal discussions do not replace any formal notice required under the Act, but they can help establish communication before the formal process begins.
Adam Joseph's guide to preventing and resolving disputes in relation to party walls offers further information on managing neighbour concerns surrounding construction projects.
Make Sure the Correct Notice Is Served
If the Act applies, the correct notice needs to be prepared and served.
The type of notice required depends on the work being proposed. Different provisions of the Act cover work to existing party structures, construction on or near boundaries and certain excavation works near neighbouring buildings.
Accuracy is important.
A notice that does not correctly describe the proposed work or follow the required procedure may lead to problems later.

Some homeowners consider preparing notices themselves. For relatively straightforward circumstances this may seem attractive, but the complexity of the project should always be considered. Adam Joseph's article on DIY Party Wall Notices explains some of the points homeowners should consider before taking this approach.
Allow Time for Your Neighbour to Respond
Serving a notice is only the beginning of the formal process.
Your adjoining owner then has the opportunity to consider the proposed works and respond.
They may consent, raise questions or dissent.
A dissent does not necessarily mean your neighbour is trying to prevent your project. It simply triggers the dispute resolution procedures contained within the Act.
This distinction is important.
The Party Wall etc. Act provides a framework through which notifiable construction work can be regulated while recognising the rights of both building owners and adjoining owners.
When surveyors become involved, their role is to deal with matters arising under the Act and establish how the relevant work can proceed.
Schedule of Condition Before Work Starts
Where appropriate, a Schedule of Condition may be prepared before construction begins.
This provides a written and photographic record of the visible condition of relevant parts of the adjoining property.
The record may include existing cracks, decorative defects or other visible conditions.
A Schedule of Condition can be valuable because it establishes evidence of the property's condition before building work begins. If concerns are raised later, there is a clear reference point available to the parties and their surveyors.
It therefore benefits both the building owner and adjoining owner.
Allow Time for a Party Wall Award
Where a dispute has arisen and surveyors have been appointed, a Party Wall Award may need to be agreed.
Depending on the nature of the project, an Award can address matters such as:
- The work that is authorised under the Act
- How particular construction activities should be carried out
- Protective measures for neighbouring property
- Access arrangements where applicable
- Working procedures
- Relevant drawings and technical information
- Procedures for dealing with certain issues that may arise
The complexity of the proposed works can influence how much information needs to be reviewed.
A straightforward residential project may progress differently from a large basement excavation or complex structural development.
This is another reason why it is sensible not to build your construction timetable around the assumption that the party wall process will always be completed immediately.
Coordinate Your Party Wall Process With Your Project Team
Your Party Wall Surveyor may need information from your architect, structural engineer or contractor.
Good coordination between the professionals involved can make the process more efficient.
For example, if additional foundation information is required, obtaining it early may prevent delays when the surveyors are considering the proposed works.
Your party wall obligations should therefore form part of your overall project programme rather than being treated as an isolated administrative task.
Our article explaining the difference between a Party Wall Surveyor and an Architect provides further guidance on the different roles professionals may play during a renovation.
Start Early for a Smoother Construction Project
There is no benefit in leaving party wall matters until the last possible moment.
Considering the Party Wall etc. Act during the early stages of your project allows you to understand whether notices may be required, communicate with neighbours and provide sufficient time for the formal process.
It can also help your architect, structural engineer, contractor and Party Wall Surveyor work within a more realistic project timetable.
Whether you are planning a loft conversion, extension, basement or structural renovation, obtaining professional guidance early can give you a clearer understanding of the steps ahead.
