Party Wall Surveyor in Barnet

Barnet’s 1930s suburbs across Finchley, Hendon and Edgware, Victorian property around Barnet town, Hampstead Garden Suburb conservation, and modern infill generate steady party wall work. The Party Wall etc. Act 1996 governs notifiable works. Our London head office in SE1 covers Barnet across north London. The London Borough of Barnet’s area generates frequent instructions on suburban extensions, conservation work in Hampstead Garden Suburb, and infill development.

Party Wall Agreements for Barnet Projects

Most Barnet projects raise party wall obligations from the design stage. Rear and side extensions to the borough's extensive 1930s suburban stock across Finchley, Hendon and Edgware, refurbishments to Victorian property around Barnet town and Whetstone, conservation work in Hampstead Garden Suburb, and infill development consented by the London Borough of Barnet all routinely require notice under the Party Wall etc. Act 1996.

CHP Surveyors has been established since 2004 with offices in Wickford, London and Hampshire. Our London head office at Boundary Row in SE1 is RICS regulated and delivers specialist chartered surveying on dense urban sites with technical depth. Barnet coverage extends from Cricklewood and Hampstead Garden Suburb through Finchley, Hendon and Edgware to Barnet town and Whetstone. Many extension projects also pair with daylight and sunlight reports at the planning design stage.

James Crowley is the past London and National Chair of The Pyramus and Thisbe Society, an organisation with a great interest in party wall and neighbourly matters.

Having been involved in projects across the UK for both domestic properties and larger, city centre developments, we have experience and knowledge of the more complicated methods of construction, including temporary restraint works, piling to form a triple basement and jet grouting. We have also negotiated licences for the use of scaffolding and tower cranes.

How is party wall work managed in Barnet?

Party wall work in Barnet is managed by a single named surveyor on each file, from first contact through to the final award. The starting point is a free initial assessment with a qualified surveyor from our London office, covering the proposed works, the relevant sections of the Act, and the notice strategy. Barnet projects typically involve party structure notices for suburban extensions, line of junction notices for new boundary walls on infill plots, and section 6 excavation notices for any deep foundation work.

After the assessment the surveyor drafts and serves the statutory notices, manages adjoining owner responses, and produces a detailed schedule of condition with photographs and full written notes. For Hampstead Garden Suburb and other conservation property the schedule includes additional detail on materials and any visible defects. Where the matter is agreed paperwork stays proportionate. Where dispute arises the party wall award is drafted properly and served. Building owners and adjoining owners across Barnet get continuity throughout.

Over the past four years, CHP have worked very successfully with us in their capacity as party wall surveyors. Through his calm, sensible approach and excellent communication skills James Crowley, in particular, gained the trust and confidence of the entire team and stakeholders. Looking forward to working with CHP again.”

What does CHP do when a Barnet notice is disputed?

When an adjoining owner dissents from a Barnet party wall notice, the matter moves into the formal award process under the Act. Each side appoints a surveyor, or both agree on a single agreed surveyor. The appointed surveyors then prepare the party wall award covering the works, conditions, schedule of condition, and any agreed protections.

For Barnet properties, where suburban extensions and infill development are common, the award stage often involves structural review and consideration of how the new work integrates with existing 1930s stock. Notice periods under the Party Wall etc. Act 1996 are fixed at two months for party structure works and one month for excavations. The building owner generally covers reasonable fees on both sides.
