At the checked Central London point, the planning-authority layer returns Westminster; within 1,400 metres it also returns the Oxford Street Development Corporation, Lambeth, Camden and the City of London. The thirty-five conservation records span several source owners. Hanway Street appears as one Camden record and one separate Westminster record, so its shared title does not erase their authority distinction. Soho, Bloomsbury, South Bank and Fleet Street further demonstrate the radius’s breadth. An exact address and property outline must therefore be located before any authority record, conservation boundary or architectural consequence is assigned to the project.
Do I need planning permission for an extension in Central London?
Sometimes, not always. Westminster is the authority returned at the checked Central London point, and named conservation records such as Soho and Covent Garden lie within 1,400 metres; if one covers your address, permitted development rights can narrow sharply. A check of your exact address against the official map, or a lawful development certificate, settles the question before you commit.

A Central London proposal should begin with cartographic certainty. If the property relates to Westminster’s Hanway Street record, its design explanation must cite that source; a relationship with Camden’s separate Hanway Street record requires an independent Camden assessment. The same conditional approach applies to Soho, Mayfair, Bloomsbury, South Bank, Fleet Street or any other returned area. These are authority-owned records rather than interchangeable neighbourhood labels. External scale, visibility and materials should be discussed only against relationships supported by the exact site check, with both Hanway Street rows retained whenever the review considers them.
Central London technical scoping should record planning authority, conservation record ownership and existing fabric as separate facts. A measured survey can establish elevations, roof, openings, boundaries and levels, but the evidence needed to explain them depends on the exact map result. The technical schedule must list Camden’s Hanway Street record and Westminster’s same-title record independently wherever they enter the review. Covent Garden, South Bank and other nearby records also retain their own sources. This structure prevents a drawing note, contextual conclusion or requirement from being transferred between authorities merely because two records share a title.
Local analysis
What matters in Central London
Central London planning-authority boundary evidence
Central London is represented by a Westminster point, yet the 1,400-metre result also contains the Oxford Street Development Corporation, Lambeth, Camden and the City of London. Plot the complete site and proposed works against current authority geometry before choosing a planning route.
Central London exact-address authority check
The same discipline applies to the two Hanway Street conservation rows: one belongs to Camden and the other to Westminster, and neither title alone establishes a boundary relationship. The verified site position determines the decision-maker and which authority-owned record may apply; nearby results remain separate evidence, not presumed participants in one combined central context.
Central London nearby conservation evidence
Central London returns thirty-five conservation rows, all of which remain distinct records. Two are titled Hanway Street, but one is owned by Camden and the other by Westminster; each must retain its authority label and be tested separately against the site.
Central London designation decision
Adelphi, Albert Embankment, Birdcage Walk and Bloomsbury are further entries in the radius, not a nearest-first ranking. A record covering the property may require area-specific evidence, while a setting relationship needs a located explanation. The shared Hanway Street title provides no basis for merging records, transferring guidance between authorities or reducing the returned count.
Central London feasibility and fee sequence
Deciding how much to spend before consent is the real first choice for a Central London project. Buy a feasibility stage on its own, and let it settle whether Westminster or a neighbouring authority would determine your application before any drawing money follows. Thirty-five conservation records sit within 1,400 metres of the checked point, so the exact-address check belongs in that first purchase, not the last.
Central London programme realities
Only once the constraint picture is fixed should planning drawings be commissioned. A householder application then runs to a statutory target of around eight weeks once validated, though nothing guarantees it. Technical design and building-regulations work are best held back until a decision arrives, because redesign after refusal wastes every detailed hour.

Central London project routes and services
Sequencing matters more than speed when a project sits in Central London. With Westminster returned at the checked point and Camden, Lambeth, the City of London and the OSDC all within 1,400 metres, the feasibility service earns its place first, pinning down the decision-maker and any nearby conservation records.
Choosing the right service in Central London
Conservation-area expertise is the natural companion here, given that thirty-five named records fall inside the radius and any of them could prove relevant once the address is mapped. Planning drawings and a managed planning application follow once the route is known. For interiors-only work, building-regulations drawings alone may be the honest recommendation. Technical design comes last, translating a consent into something a contractor can price.
Local evidence
What the local evidence tells us about Central London
Central London survey evidence
A Central London drawing package should identify the authority source behind every mapped conservation relationship. If Camden’s Hanway Street record is relevant, label it as Camden and explain that geometry; if Westminster’s separate Hanway Street record is relevant, cite Westminster and assess it independently.
Central London drawing coordination
Where both have a supported relationship to the property, show both rows and their different consequences rather than presenting one generic Hanway Street context. The same source discipline applies to Adelphi, Bloomsbury or other returned areas. Coordinate footprint, elevations, external changes and viewpoints with the verified record and the confirmed planning route.
Local process
How we would sequence a project in Central London
Central London consent-to-design sequence
The delivery sequence for Central London should include a routing checkpoint before concept approval. Confirm the site authority, then test each relevant conservation row against the full property boundary. Camden’s Hanway Street record and Westminster’s separate Hanway Street record must occupy different entries in that schedule, with the outcome for each recorded.
Central London technical delivery sequence
Prepare the planning narrative and external drawings around the supported authority context, whether Hanway Street, Soho, Bloomsbury, South Bank or another returned area. Later coordination should preserve those source labels so a shared title never turns two authority records into one submission assumption.

Central London’s evidence requires authority-labelled interpretation. Westminster is returned at the checked point; Camden, Lambeth, the City of London and OSDC occur within 1,400 metres. The conservation data includes a Hanway Street row owned by Camden and another Hanway Street row owned by Westminster. Both remain separate even though their titles match. Charlotte Street in Camden and Charlotte Street, West in Westminster reinforce the need to preserve source ownership. The correct method is to match the precise property to each live record, state the supported relationship and avoid combining several central authority contexts into one heritage description.

Why does the Central London evidence list five authorities?
Westminster was returned at the checked Central London point, while OSDC, Lambeth, Camden and the City of London appeared within 1,400 metres. Central boundaries sit close together, so the wider list is a routing warning. Even same-title records such as Camden’s and Westminster’s Hanway Street entries remain separate; the exact property check determines which authority evidence applies.
Can a Central London project rely on the nearest named conservation area?
Not without a boundary check. Central London returns records owned by several authorities, including separate Hanway Street entries for Camden and Westminster. Proximity and a matching title cannot establish inclusion or relevance. The property must be tested against each current authority map before any record is used, and two same-title rows must never be combined.
What is the first architectural task for a Central London address?
Fix the Central London route before the form: verify the property’s planning authority, then test each potentially relevant conservation row. If Hanway Street is involved, keep its Camden and Westminster records separately labelled and reach a finding on each. Elevations, roof changes, materials and supporting evidence should follow only after those authority-specific relationships are established.
Why does a property's planning history matter for a Central London extension?
Earlier decisions shape what remains possible. A past approval may already have used part of a home's extension allowance, a refusal signals what the authority resisted, and conditions on old consents sometimes remove permitted development rights entirely. In Central London, where Westminster is returned at the checked point and four other authorities sit within 1,400 metres, the history also confirms which file to search. Reading it first stops a strategy being built on rights that no longer exist.
Which extension type suits Central London homes: rear, side-return or loft?
No single route can be recommended, because Central London's stock varies too widely for a pattern to hold. A rear or side-return addition only works where there is external space to build into; a loft conversion turns on roof form and headroom, which a measured survey establishes. Flats generally lack the permitted development rights houses enjoy. With conservation records like Mayfair and Bloomsbury among those nearby, the exact-address check should precede any preference between routes.
