The London Loft Conversion Company designs and builds loft conversions across Shepherds Bush and the surrounding W12, W6 and W3 postcodes, around 15 minutes from our Fulham base. One in-house team for feasibility, design, planning, structural engineering and the build itself. One fixed price, VAT included, written contract.

The streets off Shepherds Bush Green and either side of Uxbridge Road filled up fast in the late Victorian years, and the result is tight rows of 1880s and 1890s terraces on roads like Coningham Road, Percy Road and Stowe Road. Most of them carry a rear back addition ("outrigger"), which is exactly the footprint an L-shaped dormer builds over. That makes W12 classic L-shaped territory: a master bedroom and a proper bathroom in one project, with nothing visible from the street. Straight rear dormers suit the simpler roofs toward Askew Road and Wendell Park.
Planning is refreshingly simple in one respect: the whole of W12 sits under Hammersmith & Fulham Council, so there is no council-boundary guesswork. Full applications typically take 8–10 weeks; Lawful Development Certificates, which cover most Shepherds Bush dormers, are usually decided in around 6 weeks. The main caveat is the Wormholt estate, the 1920s garden-suburb streets north of Uxbridge Road, where roof alterations are restricted and a standard dormer is unlikely to be approved. There, a low-impact Velux conversion or a carefully designed application is usually the route, and we confirm your street's exact position before quoting.
We're around 15 minutes by road from our Fulham base, straight up Fulham Palace Road and through Hammersmith, which means same-day or next-working-day survey visits across Shepherds Bush. A good share of our W12 work comes through neighbour referrals. Once one loft on a terrace is done well, the scaffolding tends to move a few doors down.

Most Shepherds Bush properties fall into two or three roof types, and the right loft conversion depends on yours. Here's the short version.
The W12 classic. Most of the Victorian terraces off the Green and either side of Uxbridge Road have a rear outrigger, and an L-shaped dormer builds over it to add two rooms, usually a master bedroom and a generous bathroom. Permitted development on the vast majority of houses outside the Wormholt estate.

£54,000 – £68,000
Read more about rear dormersThe highest-spec option for the taller terraces around the Green and the streets where a full extra storey makes sense. Rebuilds the rear roof at a steep angle to create vertical walls and maximum floor area inside. Always needs planning permission, which we prepare and submit as part of the fixed quote.

Shepherds Bush is one of the better-value corners of zone 2 west London for a loft conversion. The housing stock is the same solid Victorian terrace you find in Chiswick or Brook Green, but W12 build prices sit a notch below its smarter neighbours. The ranges below are 2026 figures for terraces in W12 and the W6 and W3 edges. Final quotes are confirmed in writing after a free home survey.
| Type | Typical range | Build time | Planning |
|---|---|---|---|
| Velux | £38,000 – £48,000 | 6–8 weeks | Usually permitted development |
| Dormer | £54,000 – £68,000 | 8–10 weeks | Usually permitted development |
| L-Shaped Dormer | £64,000 – £80,000 | 10–12 weeks | Often permitted development |
| Hip-to-Gable | Less common in W12 | – | – |
| Mansard | £74,000 – £98,000 | 12–16 weeks | Planning permission required |

From the first survey to handover, everything happened when they said it would. The fixed price genuinely was fixed, and the weekly photo updates meant we always knew exactly where the build was. The dormer has completely changed how we use the house.

Our loft was a dumping ground for ten years and now it's the nicest room we own. The crew were tidy, polite and honest about what was possible, and the finish is better than we dared hope for.

Loft conversions in Shepherds Bush typically cost £54,000 to £98,000 depending on the type and the property. A standard rear dormer on a Victorian terrace usually falls between £54,000 and £68,000. L-shaped dormers, the most common choice on the outrigger terraces off Uxbridge Road, run £64,000 to £80,000. Mansards are £74,000 to £98,000, and a Velux conversion starts from around £38,000. Every figure is VAT included and confirmed in writing after a free home survey.
Often not. Rear dormers and L-shaped dormers on Shepherds Bush houses usually fall under permitted development, needing only a Lawful Development Certificate. You will need planning permission for a mansard, for any conversion of a flat or maisonette, and for most roof work on the Wormholt estate, where alterations are restricted. We assess your street's exact position at the free survey and handle whichever route applies.
A full planning application typically takes 8 to 10 weeks with Hammersmith & Fulham. A Lawful Development Certificate, which is all most Shepherds Bush dormer conversions need, is usually decided in around 6 weeks. We prepare and submit everything, deal with any planning officer queries, and build the approval time into your project programme.
The L-shaped dormer. Most of the Victorian terraces off the Green and along the streets either side of Uxbridge Road have a rear outrigger, which is exactly the footprint an L-shaped dormer builds over, adding a master bedroom and a generous bathroom in one project. Straight rear dormers are the next most common, particularly toward Askew Road and Wendell Park.
Sometimes, but the options narrow. The Wormholt estate, the 1920s garden-suburb streets north of Uxbridge Road, restricts roof alterations, so a standard rear dormer is unlikely to be approved. A Velux conversion that keeps the roofline intact is usually the realistic route, and where more space is essential we can advise on whether a full application has a genuine chance. We give you a straight answer at the free survey rather than an optimistic one.
All of W12: the streets around the Green, both sides of Uxbridge Road, the Loftus Road and White City end, and out west through Wendell Park to Askew Road. We also work across the borders into Hammersmith W6 and Acton W3, and our Fulham base is around 15 minutes away, so survey visits are easy to arrange anywhere in the area.
