Party Wall Quote

What Is a Party Wall Surveyor?

A party wall surveyor is a specialist property professional who administers procedures under the Party Wall etc. Act 1996.

Their role is not to act solely for the building owner or adjoining owner. Instead, when appointed under the Act, a surveyor must act impartially and resolve party wall matters fairly and professionally.

A Party Wall Surveyor Greenwich typically assists with:

Determining whether the Act applies

Preparing and serving notices

Advising property owners and developers

Preparing schedules of condition

Assessing risks associated with proposed works

Negotiating with adjoining owners

Producing Party Wall Awards

Resolving disputes

Monitoring compliance with Awards

The Act provides a framework that allows building owners to undertake certain works while protecting neighbouring properties.

Why Party Wall Matters Are Common in Greenwich

The borough includes:

Georgian terraces

Victorian and Edwardian housing

Listed buildings

Conservation areas

Apartment developments

Commercial buildings

Mixed-use developments

Basement extensions

Large regeneration projects

Areas such as Greenwich Town Centre, Blackheath, Charlton, East Greenwich, Westcombe Park, Maze Hill and North Greenwich frequently see:

Many of these projects trigger obligations under the Party Wall etc. Act 1996.

Understanding the Party Wall etc. Act 1996

The Party Wall etc. Act 1996 applies throughout England and Wales.

The legislation provides rights for building owners to carry out certain works affecting shared walls, boundaries and neighbouring structures while protecting adjoining owners from unnecessary risk.

The Act does not prevent development. Instead, it establishes a legal process that must be followed before certain works commence.

Failure to comply can lead to:

Project delays

Legal disputes

Injunctions

Increased costs

Damage claims

Difficult neighbour relationships

Seeking advice from a Party Wall Surveyor Greenwich at an early stage can prevent many of these issues.

What Does a Party Wall Surveyor Greenwich Do?

Schedule of Condition

A schedule of condition records the state of adjoining property before works begin.

The document typically includes:

Dispute procedures

The Award provides clarity for all parties.

Working hours

Vibration controls

Access provisions

Security requirements

The Award protects both the building owner and adjoining owner.
