Most Harrow projects raise party wall obligations from the design stage. Rear and side extensions to the borough's extensive 1930s suburban stock across Harrow, Stanmore, Wealdstone and Pinner, refurbishments to Victorian property in Harrow on the Hill conservation area, basement digs on detached stock, and infill development consented by the London Borough of Harrow 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. Harrow coverage extends from Pinner and Stanmore through Wealdstone and Harrow town to South Harrow and Harrow on the Hill. 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.

Setting up a party wall instruction in Harrow starts with a free initial assessment by a qualified surveyor from our London office. The first conversation covers the proposed works, the relevant sections of the Act, and the notice strategy. Harrow 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 or basement work close to adjoining buildings.
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 Harrow on the Hill conservation property and Victorian stock 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 Harrow get continuity from instruction to final award.
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.”

When dispute arises on a Harrow party wall matter, the formal award process under section 10 of the Act resolves it. 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.
Most Harrow disputes settle at award stage without requiring further action. Where appeal is necessary, an aggrieved party has 14 days from service of the award to file with the county court. Notice periods under the Party Wall etc. Act 1996 cannot be shortened by agreement between parties. The building owner generally covers reasonable fees on both sides.
