The 6 metre rule is another part of section 6 of the Party Wall etc. Act. It can apply where an excavation is within six metres of a neighbouring building or structure and cuts a line drawn downwards at 45 degrees from the bottom of that building's foundations towards the excavation.
Why the 45-degree line matters
The rule is not “any digging within six metres”. It concerns a geometric relationship between proposed digging and the location and depth of nearby foundations. Without reliable dimensions and a drawing, a homeowner may not be able to assess it accurately.
What information should the designer provide?
You will typically need the position and depth of proposed foundations or excavation, and sufficient information about the relevant neighbouring building. The statutory notice must be accompanied by plans and sections, not just a text description.
Can our notice builder do this?
No. Section 6 notices are intentionally excluded because technical drawings and details are required. Our guided builder is limited to certain existing-wall and boundary-wall notices.
Does permission to build replace notice?
No. Planning permission and building regulations approval are separate from the Party Wall Act's notice requirements. Read the 3 metre rule and extension guide together before deciding what is needed.
Based on the GOV.UK explanatory booklet and the Party Wall etc. Act 1996. This is general guidance for England and Wales; the applicable rules depend on the actual work and affected owners.
