Recent Party Wall Questions

Great question. Yes — a floor/ceiling structure separating two separately owned flats is very likely a party structure within the meaning of the Act, defined under Section 20 as a wall or other structure separating buildings or parts of buildings approached by separate staircases or entrances. So the floor between you and the flat below would typically qualify.

What notices might I need?

If you're removing or significantly altering that floor/ceiling structure, you'd likely need a Section 3 Party Structure Notice, exercising rights under the relevant Section 2(2) subsection — most probably Section 2(2)(b) (demolishing and rebuilding a party structure) or Section 2(2)(f) (cutting into a party structure), depending on the exact nature of the works.

The precise subsection depends on what you're actually doing to the structure — Paul will confirm which rights need to be exercised once the design is known.

💡 In a flat scenario, there may be multiple qualifying interests to notify — the freeholder, any long leaseholders, and mortgagees in possession could all be "adjoining owners" under Section 20, so more than one notice may be required.

This is general guidance only — Metris needs to confirm your specific situation before any notice is drafted. 📧 paul@metrispws.com 📞 07511 508 674

Yes, the Party Wall Act 1996 applies to commercial properties as well as residential — the Act is not limited to houses.

What notices might be needed?

If your conversion works involve cutting into, thickening, or otherwise working on the shared wall with the commercial unit next door, you'd likely need a Section 3 Party Structure Notice exercising rights under the relevant Section 2(2) subsection — for example, Section 2(2)(f) if you're cutting into the wall for beams or services, or Section 2(2)(a) if you're raising or thickening it.

💡 With a commercial unit next door, there may be multiple qualifying interests to notify — under Section 20, adjoining owners include freeholders, leaseholders with a term exceeding one year, and mortgagees in possession, so a single neighbouring property could require separate notices for each qualifying interest.

This is exactly the kind of scenario where Paul's experience across commercial and residential projects is valuable — worth a direct conversation before works are designed.

Is there anything else I can help you with?

Great question. A 100mm setback means your new wall would be built entirely on your own land with a clear gap from the boundary, so Section 1 (Line of Junction) likely does not apply - that section is only engaged where a new wall sits on or astride the boundary itself. Similarly, Section 2 powers are not engaged since there's no party wall being worked on.

What notices might I need?

The one area to watch is excavation for your new wall's foundations - if those foundations go deeper than your neighbour's existing foundations and within 3 metres of their structure, a Section 6(5) Adjacent Excavation Notice (exercising rights under Section 6(1)) would possibly be required, assuming the excavation extends below the level of the bottom of the adjoining owner's foundations.

⚠️ Important: If a Section 6 notice is required, it must be accompanied by plans and sections showing the site and depth of the excavation (Section 6(6)) - without these it is invalid and the notice period never starts.

💡 With the wall set back 100mm from the boundary, your foundations must stay entirely within your own land - the right to project footings across the boundary only applies to walls built on the line of junction itself.

This is general guidance only - Paul at Metris can confirm whether a notice is needed once he knows the full picture. 📧 paul@metrispws.com 📞 07511 508 674

These are bare statutory facts I can answer directly:

How long does an Award take? The Act sets no fixed timeframe for an Award to be made — it depends on how quickly surveyors are appointed and how complex the works are. There is no statutory deadline.

Can works start before an Award is agreed? No. Where a dispute has arisen (or is deemed to have arisen), works cannot lawfully commence until an Award has been made under Section 10.

Yes, planning permission and the Party Wall Act are completely separate regimes - one doesn't replace the other. Planning permission is granted by the local authority and controls *what* you can build; the Party Wall etc. Act 1996 is a neighbour-notification process that controls *how* works affecting shared walls and boundaries are carried out, and protects both you and your neighbour.

To work out whether you need a notice - and which type - I'd need to know a bit more about the works you're planning. For example:

• Are you building an extension, doing a loft conversion, or something else?
• Will any works involve or affect a shared (party) wall?
• Will you be digging foundations close to your neighbour's property?

Tell me a bit about what you're planning and I can give you a clearer steer on what likely applies. 😊

📧 paul@metrispws.com 📞 07511 508 674

You don't need to know your neighbour's foundation depth before serving a Section 6(5) Notice. The Act uses the phrase "proposes to" in both Section 6(1) and 6(2) — the notice is served on the basis of your *stated intention* to excavate below the adjoining owner's foundations, accompanied by plans and sections showing the proposed site and depth of your excavation. It's a statement of intent, not a confirmed measurement.

The precise depth of your neighbour's foundations is a matter for your own engineer to advise on as part of the design — it's not something you need to establish before the notice goes out, and it's not something Metris would assess through this tool.

If there's genuine uncertainty about whether Section 6 applies to your specific project, Paul can advise once he knows the details. 📧 paul@metrispws.com 📞 07511 508 674

Great question — and a common one. Here's how to think about it:

What likely applies depends on the wall's status

For a typical semi-detached or terraced house, the wall shared with your neighbour is almost certainly a party wall under the Act — it sits astride the boundary and is used by both properties. If that's your situation, works to or affecting that wall would likely require a Section 3 Party Structure Notice exercising rights under the relevant Section 2(2) subsection (depending on exactly what you're doing to it).

If your extension is being built *next to* the boundary rather than touching the shared wall, the question shifts to whether your excavation for foundations comes within 3 metres of the neighbouring structure — which could engage a Section 6(5) Adjacent Excavation Notice.

The honest answer is: the wall's legal status matters a lot, and it's not always obvious from looking at it. A party wall surveyor can check the title deeds, inspect the structure, and confirm what applies before any notice is drafted.

Paul at Metris would be happy to take a quick look at your situation and give you a definitive steer — no obligation.

*This is general guidance only — please don't act on it without speaking to Metris directly to confirm what applies to your specific project.*

Yes - this is an unconditional requirement under the Act.

Section 6(6) makes plans and sections mandatory for any Section 6(5) Notice, regardless of whether it's served under Section 6(1) or Section 6(2). Without them, the notice is invalid and the notice period never starts.

The good news is that architect's drawings showing the site and depth of the proposed excavation normally suffice - full engineering drawings or structural calculations are not required at notice stage.

*This is general guidance only and must not be acted upon without speaking to Metris directly.*

Great question - and the answer depends on which part of the Act we're looking at.

What notices might you need?

Being more than 3 metres from your neighbour rules out Section 6(1) (the 3-metre excavation rule), but it doesn't necessarily mean no notices are needed at all. If your extension involves building on or up to the boundary line, a Section 1 Line of Junction Notice would likely apply. And if your extension connects to or works on an existing shared (party) wall - for example, a terraced or semi-detached house - a Section 3 Party Structure Notice exercising rights under the relevant Section 2(2) subsection would likely be needed too.

💡 Even beyond 3 metres, Section 6(2) could possibly apply out to roughly 6 metres if a 45-degree plane drawn down from the bottom of your neighbour's foundations would be crossed by your excavation - this depends on foundation depths and geometry that Paul would need to check.

The short answer: distance from your neighbour is only one part of the picture. To know for certain what applies to your specific project, it's worth having a quick conversation with Paul.

Metris does not currently accept instructions for basement or deep-excavation projects - this is a deliberate scope decision for the practice. Paul is happy to point you toward a suitable specialist, or you're welcome to get in touch to discuss your situation.

However, to give you a general sense of what's involved: basement and deep-excavation projects like this typically require an Adjacent Excavation Notice under Section 6 of the Act, and often a Party Structure Notice too if the works involve cutting into or underpinning a party wall. Given the depth and complexity involved, security for expenses and a Schedule of Condition are also commonly relevant. A specialist party wall surveyor experienced in basement work will be able to advise you properly on the specifics.

What notices likely apply?

Yes, removing a chimney breast from a shared wall almost certainly engages the Party Wall etc. Act 1996. You'd likely need a Section 3 Party Structure Notice, exercising rights under Section 2(2)(g) - which covers cutting away from a party wall any projection such as a chimney breast. If the removal also involves inserting a steel or beam into the party wall to support the remaining chimney stack above, Section 2(2)(f) (cutting into a party structure) would likely also need to be named in the same notice.

💡 A Section 2(2)(f) notice cannot be properly drafted until the engineering design is finalised - beam sizes and padstone specifications need to be confirmed before the notice goes out.

This is exactly the kind of work Metris handles regularly - Paul can confirm which subsections apply to your specific situation and get the notice drafted correctly.

What notices likely apply?

Chasing into a party wall to run services counts as cutting into a party structure, which likely engages Section 2(2)(f) of the Act — the right to cut into a party structure for any purpose. The procedural mechanism for exercising that right is a Section 3 Party Structure Notice, served on your neighbour at least 2 months before works begin.

This is what likely applies based on what you've described, but Metris needs to confirm your specific situation before any notice is drafted or served.

💡 Section 2(2)(f) works carry a statutory duty to make good all damage caused to the adjoining premises — including internal finishes and decorations — so the scope of the chasing and reinstatement should be clearly defined before the notice goes out.

Good question - this is one of those areas where the answer isn't as clear-cut as the picture-hook example.

What likely applies?

Chemical DPC installation involves drilling a series of holes at regular intervals along the base of a party wall, often at significant depth, to inject a water-repellent fluid. Unlike a picture hook, this is a systematic, repetitive intervention across the full thickness of a shared structure. It's at least arguable that this constitutes "cutting into a party structure" under Section 2(2)(f), which would require a Section 3 Party Structure Notice - though whether it crosses the threshold from minor drilling to a notifiable intervention is genuinely debated among surveyors.

The key distinction is likely scale and structural impact: a single drill hole for a fixing is de minimis; a row of closely-spaced holes along the full length and depth of a wall base is a different proposition, and some surveyors would say it's notifiable.

As always, this is general guidance only and Metris needs to confirm your specific situation - but it's exactly the kind of borderline question worth a quick call with Paul before you proceed.

Great question — and the short answer is: possibly yes, the timing of the original demolition doesn't change your current obligations.

What notices might apply?

If you're excavating to remove old foundations within 3 metres of your neighbour's building, a Section 6(5) Adjacent Excavation Notice exercising rights under Section 6(1) would possibly be required — assuming the excavation extends below the level of the adjoining owner's foundations. The fact that the house was demolished 10 years ago by someone else is irrelevant — what matters is what *you* are doing *now* and how close it is to your neighbour's structure.

⚠️ Important: A Section 6 notice must be accompanied by plans and sections showing the site and depth of the excavation (Section 6(6)) — without these it is invalid and the notice period never starts.

💡 If the old foundations extend deeper than your neighbour's, even what looks like a straightforward removal job can trigger Section 6 — worth getting Paul to assess before you start.

This is general guidance only and must not be acted upon without speaking to Metris directly — Paul needs to confirm your specific situation.

This tool is for working out what notice you need for upcoming works - it isn't set up to advise on disputes or awards that have already happened. That's something Paul needs to look at directly:

📧 paul@metrispws.com 📞 07511 508 674

This is really a question about timing and procedure rather than which notice applies to specific works — but it's an important practical point, so here's the short answer:

Almost certainly not. A Section 6(5) Adjacent Excavation Notice (which would likely apply to new foundations near a boundary) carries a 1-month minimum notice period before works can lawfully begin. A Section 3 Party Structure Notice (if the works also involve an existing party wall) requires 2 months. Three weeks isn't enough time for either.

⚠️ Important: A Section 6(5) Notice must be accompanied by plans and sections showing the site and depth of the excavation (Section 6(6)) — without these it is invalid and the notice period never starts. Those drawings need to be ready *before* the notice is served, which takes further time to arrange.

Paul needs to look at this urgently — the earlier he's instructed, the better the chance of managing the programme realistically.

If your neighbour is building an extension, they may well owe you notice under the Party Wall etc. Act 1996 — depending on what exactly they're doing. Here's what's typically involved:

What notices might apply to their works?

• If they're digging foundations within 3 metres of your property, they'd likely need to serve a Section 6(5) Adjacent Excavation Notice on you (exercising rights under Section 6(1)).
• If they're working on a shared party wall — cutting into it, raising it, or underpinning it — they'd likely need a Section 3 Party Structure Notice (exercising rights under the relevant Section 2(2) subsection).
• If they're building a new wall on or at the boundary, a Section 1 Line of Junction Notice may also be required.

As the adjoining owner, your options on receiving any notice are:

1. Consent — works proceed, but you'd have no Award protecting you upfront 2. Dissent — surveyors are appointed, an Award is made protecting your interests before works start 3. Silence — treated as a deemed dispute, but if you then fail to appoint a surveyor within 10 days of a follow-up request, your neighbour can appoint one on your behalf under Section 10(4)

💡 An adjoining owner who appoints their own surveyor will usually have those reasonable costs paid by the building owner, provided the works are solely for the building owner's benefit.

If works have already started without notice, that's something Paul needs to look at directly — 📧 paul@metrispws.com or 📞 07511 508 674.

Great question — and the answer depends on exactly where along the boundary you're building.

What notices might apply?

If your new fence/wall sits on the line of junction (the shared boundary line where there's currently no built structure), Section 1 of the Party Wall etc. Act 1996 likely applies. If you want the wall to straddle the boundary, you'd need your neighbour's written consent under Section 1(2). If they don't consent (or don't reply within 14 days), you can still build — but wholly on your own land under Section 1(4). If you're planning to build wholly on your own land from the outset, a notice under Section 1(5) is likely required.

If the wall is genuinely set back from the boundary with a clear gap, Section 1 likely doesn't apply at all.

💡 Even a modest wall or fence will involve some excavation for footings — if those go deeper than your neighbour's existing foundations and within 3 metres of their structure, a Section 6(5) Adjacent Excavation Notice might also be needed.

This is general guidance only — Metris needs to confirm your specific situation before any notice is prepared. Paul is happy to have a quick chat: 📧 paul@metrispws.com 📞 07511 508 674

This is a common misconception worth clearing up. Cutting into a party wall to insert a steel beam — including the beam pockets and padstones needed to seat it — almost certainly engages Section 2(2)(f) of the Act, regardless of how far the beam penetrates. The depth of the cut doesn't change the statutory position; what matters is that you're cutting into a party structure.

What notice likely applies?

You'd likely need a Section 3 Party Structure Notice exercising rights under Section 2(2)(f) (cutting into a party structure).

💡 One practical point worth knowing: a Section 3 Notice for beam works can't be properly drafted without the engineering design in place first — beam sizes and padstone specifications need to be confirmed before the notice goes out, so it's worth getting your structural engineer to sign off the design before Metris prepares the notice.

This is exactly the kind of situation where a quick conversation with Paul is worthwhile — builder assumptions about the Act are often well-intentioned but not always accurate.
