Where do Hammersmith and Fulham’s conservation area boundaries run?

Below is a plan of the borough with each designated area drawn from the national planning register, and a postcode search that resolves inside the page rather than on a server. Use it to see which side of a line you are on, not to decide it: the polygons carry a small amount of simplification, and half a metre matters when a boundary passes through your own plot.

Forty-seven areas are registered here across 959 hectares, and no one of them dominates. The largest, Old Oak & Wormholt, is 79.7 hectares — under a tenth of the designated total — and the smallest, The Billings & Brompton Cutting, is half a hectare. That patchwork shape is the practical point: cross a main road in this borough and you can leave one designated area and enter another with a different character and a different appraisal behind it. Two gaps in the record are worth knowing before you start. The national register holds no designation date for any Hammersmith and Fulham area, and it links no council document to any of them either, so the character appraisal that will eventually be quoted back at you has to be found on the council’s own site. No Article 4 directions have been uploaded for the borough. That is a gap in the register, not evidence that none apply, and it should be checked with the council directly.

Answers for Hammersmith and Fulham

How many conservation areas does Hammersmith and Fulham have?

Hammersmith and Fulham designates 45 conservation areas — Hammersmith Grove, Brackenbury Village, Fulham Palace Road, Parsons Green and Walham Green among them. Designation is not the only map an address is checked against here. At 51.94% of its land in Flood Zone 3, this is the most extensively mapped of the 33 boroughs, ahead of Southwark on 43.16% and Newham on 39.4% (Environment Agency, retrieved 2 September 2026), and the two layers overlap along the Fulham riverside. The Environment Agency is explicit that a borough share describes an area of land rather than an individual property, so we check the address itself before specifying anything.

What changes need planning in a Hammersmith and Fulham conservation area?

Any external alteration visible from a public space typically requires full planning permission inside a conservation area: roof additions, dormers, replacement windows, rendering, hardstanding, and demolition. Internal works generally do not, unless the property is also listed.

Do I need a Heritage Statement in Hammersmith and Fulham?

Yes. Every application inside one of the borough's conservation areas carries a Heritage Statement, and it has to answer the character appraisal the council has adopted for that specific area, name the assets a scheme affects, and set out what the design preserves. In Hammersmith and Fulham a second document often travels with it: Flood Zone 3 covers 51.94% of the borough's 16.4 sq km of land, the largest share of any London borough on the Environment Agency Flood Map for Planning (retrieved 2 September 2026), so a great many designated addresses also need a Flood Risk Assessment in the same submission. We write both.

Can I have a roof extension or mansard in a Hammersmith and Fulham conservation area?

Roof work is judged against the terrace it belongs to. Where the existing roofscape along a run of houses is consistent, a rear mansard or a dormer set behind the ridge is a normal outcome even in a designated street; a dormer on the front slope is not, and it is refused as a matter of routine. The decision record says the same thing from the other end. Of 1,569 householder decisions Hammersmith and Fulham made across the three years of MHCLG returns ending March 2026, 62 were refusals (PS2, Open Government Licence v3.0). A refusal in this borough usually means a design that ignored the roof it sits on.

How long does conservation area approval take in Hammersmith and Fulham?

Hammersmith & Fulham Council statutory determination is 8 weeks for householder applications. Conservation officer consultation adds 2–3 weeks in practice. Expect 11–14 weeks from validation to decision.

Which Hammersmith and Fulham postcodes does this conservation area application service cover?

In most London boroughs a conservation area is the exception you check for. Here it is closer to the default: 47 designated areas covering 958.9 hectares of a borough of roughly 1,640 (planning.data.gov.uk conservation area register, retrieved 1 September 2026). The table below lists the districts we draw in. Fees quoted are the statutory England rates for 2026, not our estimates.

PostcodeAreaDominant stockWhat it means for a conservation area application
SW6Fulham / Parsons GreenVictorian terraces, mansion blocksFulham / Parsons Green sits wholly inside SW6, so Hammersmith & Fulham Council validates every conservation area application submitted from an SW6 address.
W6Hammersmith / Brackenbury VillageVictorian terraces, mansion blocksHammersmith / Brackenbury Village sits wholly inside W6, so Hammersmith & Fulham Council validates every conservation area application submitted from an W6 address.
W12Shepherd's Bush / White CityVictorian and Edwardian terracesW12 covers Shepherd's Bush / White City only; Hammersmith & Fulham Council handles the conservation area application.
W14West Kensington / Barons CourtVictorian and Edwardian villasWest Kensington and Barons Court sit on the Hammersmith and Fulham border with Kensington and Chelsea, and W14 covers ground on both sides, so an application from this postcode can land with either authority. We settle which one first, from the address, because each council adopts its own appraisals and quoting the wrong one is a validation problem rather than a drafting one.
SW10West Brompton / World's EndGeorgian and Victorian terraces, listed buildingsSW10 crosses the same boundary in the other direction at West Brompton and World's End. Determination follows the address, not the postcode, and the two councils' policies maps are both checked before drawing work begins — along with the flood layer, since the southern end of SW10 runs down to the river.

What changes about a conservation area application in each part of Hammersmith and Fulham?

The clearest evidence of how much of this borough is designated is not a map, it is a count. Hammersmith and Fulham determined just ten larger householder prior approvals — the deep single-storey rear extension route — in the three years to March 2026 (MHCLG planning application statistics, PS1, retrieved 1 September 2026). Croydon determined 529 in the same window. Ten cases is far too thin to draw a rate from, and we are not offering one; the number is worth quoting only because it shows the permitted development route barely operates here.

How do conservation areas and Article 4 affect a conservation area application in Hammersmith and Fulham?

Designation costs you the route, not the answer. A house inside one of these areas stands on article 2(3) land, so Class B roof enlargements, side extensions, two-storey rear extensions and cladding all leave permitted development, and what would have been a £274 certificate or a £249 prior approval becomes a £548 householder application. What it does not usually cost is consent. Hammersmith and Fulham approved 1,507 of the 1,569 householder applications it decided in the three years to March 2026 — 96.0%, the highest rate of the 32 boroughs the figure can be calculated for and thirteen points above the London average of 83.0% (MHCLG planning application statistics, retrieved 1 September 2026).

The same holds for listed buildings, which is more surprising. The council decided 119 listed building consent applications to alter or extend over those three years and granted all 119 — the only London borough with a clean sheet on that measure, against a pooled London rate of 91.2%. Read alongside 260 certificate of lawful development applications, a very low count for a borough of this size, the picture is consistent: here almost everything goes through the application process, and almost everything that does gets through it.

The price is time. Hammersmith and Fulham agreed an extension of time on 59.6% of everything it decided — nearly six applications in ten, against 34.5% across London and second highest of the 33 authorities — and only 88.3% of its householder decisions landed inside eight weeks. Plan on months rather than weeks, and use them: a scheme that answers the character appraisal before it is submitted is what this borough rewards. The Article 4 direction, which covers HMO conversion and some ground-floor shop-to-residential changes, sits on top of all this and is checked address by address on the policies map.
