London
Harlesden’s checked point returns the Old Oak and Park Royal Development Corporation, or OPDC, rather than a London borough. Ealing and Brent also appear within 1,400 metres. Nearby conservation records include Harlesden and its extension, Old Oak Lane, Canalside northeast, Grand Union Canal and Kensal Rise. This makes authority verification central to architectural scoping. The locality name cannot determine whether OPDC, Brent or Ealing handles an address, and the returned conservation names remain proximity evidence until checked on official maps.

A Harlesden design brief should reserve authority-dependent advice until the property is plotted against OPDC, Brent and Ealing boundaries. If the official conservation map confirms Harlesden, its extension, Old Oak Lane or a canal-related designation, external form, openings, materials and visible services may need a context-specific explanation. If no boundary applies, those nearby names should not be used as controls. The authority result also matters when reviewing precedent: a physically close scheme assessed by Brent may not provide the same procedural or policy signal for an OPDC site.
Harlesden technical coordination should identify which elements cross from construction performance into planning appearance. Roof equipment, façade upgrades, ventilation, drainage and access-related external works can become authority-sensitive. Because OPDC, Brent and Ealing appear within the search, the responsible body should be confirmed before those details are final. The returned Harlesden, Old Oak Lane and Grand Union Canal records sharpen the map review but do not dictate solutions. Structure, fire, acoustics, energy and weathering should then be integrated with the verified external scope and consent path.
Local analysis
Harlesden cannot be routed safely by borough shorthand because the checked point returns the Old Oak and Park Royal Development Corporation. Brent and Ealing also appear in the surrounding authority evidence. Plot the full address against the current official boundaries and record whether OPDC, Brent or Ealing is competent before selecting a portal, fee or precedent.
OPDC’s point result belongs to that coordinate; it neither governs every Harlesden address nor creates shared control with the boroughs. This written route should precede designation research so development-corporation and borough records stay correctly attributed.
Harlesden’s six records divide between two source owners. Canalside, northeast part, Grand Union Canal Conservation Area and Old Oak Lane are returned under OPDC; Harlesden, Harlesden - extension and Kensal Rise - new are Brent records. Ealing appears in the authority search but owns none of these listed designations.
Once responsibility is known, compare the property with the appropriate official polygons and preserve every exact title, especially the extension. A match may support a focused account of outward work; radius proximity alone cannot attach canal, neighbourhood or conservation status to the address.
Local evidence
Give every Harlesden drawing issue an ownership label. The site sheet should state OPDC, Brent or Ealing and pair any verified designation with that source owner—for example, Old Oak Lane under OPDC or Harlesden - extension under Brent.
The measured information should then locate the real roof, openings, external envelope, access work and visible services affected. Do not abbreviate a canal or extension record into generic local context, and do not infer construction from it. Clear ownership on titles and notes stops a development-corporation requirement from drifting into a borough route during later coordination.
Useful local facts
A Harlesden homeowner should send the exact address before asking which council or planning process applies. The initial review can test OPDC’s point result against the site, examine Brent and Ealing proximity, and check Harlesden, Harlesden extension, Old Oak Lane and canal-related conservation boundaries.
Any prior application should be identified by authority as well as by distance. This information lets the architect define an honest first stage and prevents fees, timescales or documents being based on the familiar borough name rather than the body responsible for the property.
Local process
A Harlesden project should issue a formal planning-authority note before design freeze. It needs to record OPDC as the point result, explain whether the actual address falls to OPDC, Brent or Ealing, and state the checked outcome for nearby conservation records.
Planning correspondence, drawing titles and submission portals can then follow the same authority. Once consent parameters are understood, building-regulations and tender documents should preserve approved external details. This sequence reduces the substantial risk of cross-authority assumptions contaminating consultant scopes or contractor pricing.
Decision checklist
A Harlesden option appraisal should separate OPDC decisions from borough decisions before assessing design similarity. Place the subject address in the correct authority column, add its verified conservation outcome and describe the visible work. Only precedents matching those entries should influence the preferred option.
A Brent approval cannot be repurposed for an OPDC site merely because it is close, and a nearby canal record adds nothing without a mapped intersection. Record outstanding authority-dependent work and fees rather than guessing them. This creates a defensible route through Harlesden’s unusual mix of development-corporation and borough evidence.

Local planning
The Harlesden record must not be simplified to “Brent planning.” OPDC is the authority at the research point, with Brent and Ealing nearby, and the conservation dataset spans records associated with that wider boundary context. Harlesden and Harlesden extension are separate results; Old Oak Lane and the canal-related records also have their own extents. An address review needs to establish the competent planning authority first, then the relevant designation if any. Without both checks, an application could use the wrong validation route or claim a conservation context the point search did not prove.
