Conservation areas exist to protect places of special architectural or historic interest.
That can create additional planning controls over alterations, demolition and development.
But homeowners sometimes assume that being in a conservation area fundamentally changes the Party Wall process.
Usually, it does not.
The Party Wall Act and conservation-area controls are separate
The Party Wall etc. Act 1996 applies according to the type and location of the proposed works.
Typical triggers remain:
- new walls at the line of junction;
- work to party walls or party structures; and
- qualifying excavation near neighbouring buildings.
Conservation-area status does not itself create or remove those triggers.
Planning controls may be more sensitive
What conservation-area status can change is the wider planning context.
External alterations may receive closer scrutiny.
Materials, roof forms, demolition, windows, elevations and boundary treatments may be particularly important.
Obtaining planning permission does not remove Party Wall obligations where the Act applies.
Likewise, complying with the Party Wall Act does not amount to planning permission.
Traditional buildings can require more careful design
Conservation areas frequently contain:
- Victorian terraces;
- Georgian houses;
- Edwardian properties;
- traditional masonry;
- shallow foundations;
- historic parapets;
- chimney structures; and
- older roof forms.
The age and construction of the building can make the engineering and Party Wall methodology more important.
Demolition in a conservation area
Demolition can create both planning and Party Wall implications.
Removing an attached structure might expose a shared wall to weather or alter the support conditions of neighbouring construction.
The Party Wall consequences should be considered independently from any conservation-area consent requirements.
Extensions
A rear extension in a conservation area may still trigger Sections 1, 2 or 6 in exactly the same way as an equivalent extension elsewhere.
The architectural design may differ because of planning requirements, but the Party Wall analysis still depends on the construction.
Roof works
Conservation areas can impose tighter planning control over roofs and elevations.
Where approved roof works also require:
- raising a party wall;
- cutting steelwork into it;
- changing parapets; or
- inserting flashing,
the Party Wall process may still apply.
For the statutory works themselves, see Simple Survey’s Section 2 Party Wall Guide.
Does the Party Wall surveyor decide whether the design is attractive?
No.
The Party Wall surveyor is not the conservation officer.
Their role is not to determine architectural merit.
They focus on disputes within the Party Wall Act.
Listed buildings are different again
A listed building within a conservation area may require Listed Building Consent for particular works.
That adds another separate legal regime.
The key point
Conservation-area status does not replace, suspend or expand the Party Wall Act.
It means the project may have additional planning and heritage constraints operating alongside it.
Simple Survey can help
If you are planning structural work to a property in a conservation area, Simple Survey can review the Party Wall implications while your architect deals with the planning and heritage aspects.
