The Party Wall etc. Act 1996 is separate from planning permission and Building Regulations. Some extension and loft-conversion works can fall within the Act, particularly work to an existing party wall, new boundary walls or excavations near neighbouring structures.
Common situations that may engage the Act
Government guidance identifies work such as cutting into a party wall to take the bearing of a beam, raising or rebuilding a party wall, building at or astride a boundary and certain excavations within 3 or 6 metres of neighbouring structures.
Planning permission does not remove Party Wall duties
Obtaining planning permission or Building Regulations approval does not remove obligations under the Party Wall etc. Act where it applies. Likewise, agreement under the Act does not replace planning or Building Regulations requirements.
Loft conversions can involve party-wall work
A loft conversion in a terraced or semi-detached house can involve beams bearing into a party wall or other works to the shared structure. Those details should be identified early so the homeowner can obtain appropriate Party Wall advice where needed.
Extensions can involve excavation and boundary work
New foundations close to a neighbour may trigger the excavation provisions depending on distance, depth and the neighbouring foundations. Boundary wall proposals can also fall within the Act.
Archi Project scope
Archi Project does not include Party Wall surveyor services in the standard architectural package. We can identify obvious design interfaces, but formal Party Wall advice or notices should be handled by a suitably competent adviser where required.
Frequently asked questions
Is the Party Wall Act part of planning permission?
No. It is a separate legal regime.
Does a loft-conversion beam automatically mean I need a Party Wall notice?
It depends on the actual work and shared structure. Cutting into a party wall for beam bearings is one of the examples covered by government guidance.
Does Archi Project act as Party Wall surveyor?
Not as part of the standard architectural package.
