Rarely, on the evidence. The borough recorded 8 larger home extension grants and 2 refusals across twelve quarters, too few for a published rate, and no prior-approval-not-required decisions at all. It issued 260 lawful development certificates, and withdrew 15.9% of applications before decision.

Answers for Hammersmith and Fulham

What can I build under PD in Hammersmith and Fulham without planning?

Single-storey rear extension up to 3m deep (attached house) or 4m (detached); side extension up to half the original width; loft conversion up to 40m³ (terraced) or 50m³ (semi-detached); single-storey outbuilding within the curtilage; replacement windows and doors. All subject to material match, eaves setback (20cm), and not facing a highway.

Does Permitted Development apply to flats in Hammersmith and Fulham?

No. Permitted Development rights apply only to houses (Class C3 dwellings). Flats and maisonettes require full planning for almost every external alteration.

Are PD rights different in a conservation area?

Yes — significantly reduced. In a conservation area: side extensions and two-storey rear extensions are not PD; cladding is not PD; chimney removal needs planning; roof additions are restricted.

What is a Lawful Development Certificate?

An LDC is a formal confirmation from the council that your proposal is lawful PD — recommended before building, useful when selling. Costs around £103 for council fees + drawings.

Do I need building regulations even under PD?

Yes. Building regulations are entirely separate from planning. Permitted Development removes the planning requirement only — you still need building control sign-off for structure, insulation, fire safety, drainage, and ventilation. We deliver both planning and building regs drawings.

Which postcode districts around Hammersmith and Fulham do we cover for permitted development scheme work?

Every Hammersmith and Fulham postcode district we draw in, the stock that dominates it and the authority that validates a permitted development scheme there. Hammersmith and Fulham fees below are the statutory England rates for 2026, not permitted development scheme estimates.

PostcodeAreaDominant stockWhat it means for a permitted development scheme
SW6Fulham / Parsons GreenVictorian terraces, mansion blocksA permitted development scheme at an SW6 address in Fulham / Parsons Green is determined by Hammersmith & Fulham Council under its own Local Plan policies for Fulham / Parsons Green.
W6Hammersmith / Brackenbury VillageVictorian terraces, mansion blocksHammersmith / Brackenbury Village sits wholly inside W6, so Hammersmith & Fulham Council validates every permitted development scheme submitted from an W6 address.
W12Shepherd's Bush / White CityVictorian and Edwardian terracesShepherd's Bush / White City sits wholly inside W12, so Hammersmith & Fulham Council validates every permitted development scheme submitted from an W12 address.
W14West Kensington / Barons CourtVictorian and Edwardian villasA permitted development scheme in West Kensington / Barons Court may land with Hammersmith & Fulham Council or RBKC Planning — W14 crosses the boundary, and the W14 policies map decides it street by street.
SW10West Brompton / World's EndGeorgian and Victorian terraces, listed buildingsSW10 straddles a boundary: West Brompton / World's End addresses fall to RBKC Planning or Hammersmith & Fulham Council, so confirm which authority validates the permitted development scheme before submitting SW10 drawings.

Which Hammersmith and Fulham neighbourhoods suit a permitted development scheme best?

Roof pitch, wall build-up and plot depth change every few Hammersmith and Fulham streets, and each one changes what a permitted development scheme can achieve at that address.

Does Hammersmith and Fulham planning policy restrict a permitted development scheme?

How designation changes a Hammersmith and Fulham permitted development scheme: Hammersmith & Fulham Council maintains 45 conservation areas, including Brackenbury Village, Fulham Palace Road, Parsons Green. Inside any of them a Hammersmith and Fulham permitted development scheme cannot rely on permitted development, and the route becomes a £548 householder application determined in 8 weeks rather than a £249 prior approval in 6 weeks. Hammersmith Grove sets the tone for Hammersmith and Fulham casework.

Hammersmith and Fulham and Article 4: Article 4 removes PD for HMO conversions; restrictions on ground-floor shop-to-residential in certain streets. A permitted development scheme planned at a SW6 address is checked against that direction first; Hammersmith & Fulham Council publishes the Hammersmith and Fulham extent, and the SW6 line rarely follows the Hammersmith and Fulham boundary you would expect.

Hammersmith and Fulham housing stock: Victorian and Edwardian terraces — particularly two-storey bay-fronted terraces south of the river in Fulham and Parsons Green; mansion blocks along main roads. Suburban-feel residential streets with strong conservation area coverage; well-established mansard precedents on many terraces. Read that before choosing a permitted development scheme route in Hammersmith and Fulham — construction, not postcode, sets what is achievable.
