Which Hammersmith and Fulham postcodes does this loft conversion service cover?

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

W12Shepherd's Bush / White CityVictorian and Edwardian terracesW12 covers Shepherd's Bush / White City only; Hammersmith & Fulham Council handles the loft conversion, and Shepherd's Bush / White City case officers apply the W12 conservation-area map.
W14West Kensington / Barons CourtVictorian and Edwardian villasWest Kensington / Barons Court is split at W14. Either Hammersmith & Fulham Council or RBKC Planning can determine a loft conversion here, so the W14 address is checked against both policies maps first.
SW10West Brompton / World's EndGeorgian and Victorian terraces, listed buildingsA loft conversion in West Brompton / World's End may land with RBKC Planning or Hammersmith & Fulham Council — SW10 crosses the boundary, and the SW10 policies map decides it street by street.

Hammersmith Grove is the Hammersmith and Fulham designation that most often changes a loft conversion design.

What Article 4 removes near Hammersmith and Fulham: Article 4 removes PD for HMO conversions; restrictions on ground-floor shop-to-residential in certain streets.

Do I need planning permission for a loft conversion in Hammersmith and Fulham?

It depends on your exact address in Hammersmith and Fulham. Most standard loft conversions qualify as Permitted Development (no planning permission needed) if under 40m³ for terraced or 50m³ for semi-detached, with matching materials and 20cm eaves setback. However Hammersmith and Fulham has Article 4 Directions that may remove these rights — and flats, conservation areas and listed buildings always require full planning. We confirm permitted development eligibility at the free feasibility visit.

How much does a loft conversion cost in Hammersmith and Fulham?

Two costs matter for a Hammersmith and Fulham loft: our architectural package (planning route, building regulations and structural calculations, quoted as one fixed figure) and the builder's construction cost, which varies with loft type — a standard dormer is materially cheaper to build than a mansard. We quote the design fee up front; see our fees.

Can I have a mansard loft in Hammersmith and Fulham?

Very often yes in Hammersmith and Fulham. Rear mansards are routinely approved by Hammersmith & Fulham Council where the design matches the terrace — including within conservation areas like Hammersmith Grove. A Heritage Statement and sensitive design following the borough's published guidance are essential for conservation area mansards.

What's the minimum head height for a loft conversion in Hammersmith and Fulham?

2.3m measured from existing ceiling joist to existing ridge is the practical minimum for a standard conversion in Hammersmith and Fulham. Below 2.2m usually requires dropping the ceiling below (reducing rooms on the floor beneath) or redesigning as a mansard.

Will my neighbours in Hammersmith and Fulham affect my loft conversion?

Most Hammersmith and Fulham loft conversions trigger Party Wall Act notices — legal notices to all adjoining owners. Rear dormers can also prompt right-to-light considerations in dense terraced streets, particularly in Hammersmith Grove. We handle both processes.

What types of loft conversion suit Hammersmith and Fulham homes?

Hammersmith and Fulham's victorian and Edwardian terraces — particularly two-storey bay-fronted terraces south of the stock lends itself to rear dormers (most common), hip-to-gable (semi-detached), and mansard (period terraces and conservation contexts). Velux-only conversions are possible where ridge height allows. We recommend the best structural and planning route at survey.

We cover all Hammersmith and Fulham postcodes — W6, W12, W14, SW6, SW10 — with surveyors based locally. Survey appointments within 3 working days. Our structural engineer is London-based and attends site when required.

Do I need a Party Wall agreement for a loft conversion in Hammersmith and Fulham?

We can co-ordinate the notice process; our in-house engineer handles the structural element. The Act gives neighbours 14 days to respond.
