Hounslow contains the Brentford reference coordinate; Ealing joins the authority evidence only at the 1,400-metre radius scale. Within the conservation radius, the dataset returns St Paul’s, Brentford and The Butts, together with Canalside, southeast part, Grand Union Canal and Boston Manor, and Isleworth Riverside. Those records create several possible contextual directions, but none proves that an individual Brentford address is designated. The useful architectural conclusion is narrower: establish the exact Hounslow site position, identify any boundary or setting relationship, and avoid applying a canal, riverside or conservation label solely from proximity.

A Brentford proposal that changes an external envelope should first be tested against Hounslow’s live conservation mapping. If St Paul’s, Brentford, The Butts or Canalside, southeast part is confirmed as relevant, the submission may need to show how massing, roof form, openings and materials respond to that specific context. Grand Union Canal and Boston Manor or Isleworth Riverside should not be invoked unless the address-level evidence supports a relationship. The nearby Ealing result is most useful as a warning that a visually close precedent may have been assessed by a different authority.
Technical preparation in Brentford should preserve the distinction between mapping evidence and design evidence. The GLA planning-authority layer’s Hounslow result at the checked Brentford research point sets the authority route; a measured survey then establishes what is actually changing. Where a returned conservation boundary is relevant, accurate elevations and sections can describe visibility, junctions and material transitions without promising an outcome. Where no returned nearby record applies, the same drawings still support coordination, but the project should omit unsupported heritage claims. Ealing-side information belongs in the file only if the exact Brentford location makes the neighbouring authority material pertinent.
Local analysis
Brentford’s checked point is under Hounslow, but Ealing also appears in the 1,400-metre authority result. The practical question is whether the actual red line, an access route or any proposed boundary work approaches that administrative edge; only then would the second authority affect design coordination.
Show the site against current authority geometry and use the result to select the planning portal, policy references and pre-application contact. This approach does not assume Hounslow for every Brentford address, and it avoids treating Ealing’s presence in a circular search as evidence of joint control.
Brentford has seven returned conservation records. They are Canalside, southeast part; Grand Union Canal & Boston Manor; Isleworth Riverside; Osterley Park; Spring Grove; St Paul’s, Brentford; and The Butts. The canal and riverside wording does not describe one continuous designation.
Compare every plausible polygon with the property and distinguish coverage from a defined setting relationship. A Canalside result may make a particular outward view relevant, while The Butts or St Paul’s, Brentford would identify a different mapped context. Each architectural consequence must therefore be supported by its own title and boundary evidence.
Local evidence
For Brentford, two canal-related names are easy to conflate: Canalside, southeast part and Grand Union Canal & Boston Manor. Test them independently before defining the drawing scope. If one is relevant, locate its boundary on the site or context plan and choose a section or viewpoint that demonstrates the proposal’s actual spatial relationship to it; if both are relevant, explain each separately.
The measured existing and proposed drawings should still concentrate on the altered building elements. A canal label, by itself, does not justify generic waterside imagery or a combined conservation annotation.
Useful local facts
For a Brentford homeowner, the best first instruction is an exact address plus photographs showing the elevations and boundaries likely to change. We would confirm Hounslow, inspect the live position of St Paul’s, Brentford, The Butts and the other returned areas, and note whether Ealing’s nearby boundary has any practical bearing.
The result should be a short route note identifying confirmed, possible and irrelevant records. That gives the design team a defensible starting point without claiming canal-side, riverside or conservation status that the radius search alone cannot establish.
Local process
The Brentford programme should lock the Hounslow route before planning and technical work diverge. A boundary review can then rank St Paul’s, Brentford, The Butts, Canalside and the other nearby conservation records as relevant or irrelevant to the site.
Design options should be compared only after that ranking, so the selected scheme responds to confirmed constraints. Later technical drawings can carry forward the approved external principles while resolving structure and weathering. This sequence prevents a nearby Ealing precedent or an unrelated Osterley Park record from steering the project without evidential support.
Decision checklist
The Brentford option review should begin with the choice most likely to alter the project route: which authority contains the supplied address. If current mapping confirms Hounslow, use that conclusion; if it identifies Ealing, replace the assumed route before further design coordination.
Next decide which, if any, of the seven conservation polygons creates a real design question. The preferred option should be supported by the particular drawing that answers that question, whether it concerns boundary position, visible scale or setting. This sequence prevents a point result from becoming an untested address claim.

Local planning
Brentford’s evidence is led by Hounslow rather than by the nearest recognisable conservation name. Ealing’s appearance within 1,400 metres means borough-edge precedents need particular care. The returned list ranges from St Paul’s, Brentford and The Butts to Osterley Park and Spring Grove, so it describes a varied search field rather than one uniform character area. For a planning brief, each named record should be treated as a question to resolve on the official map. Only the designation tied to, adjoining or materially relevant to the actual Brentford site should inform the explanation of design consequences.
