House Extensions · W12 Shepherd's Bush
W12 borders the major White City regeneration; Hammersmith & Fulham applies householder control across the terraced streets around Askew Road.
The borough-level guide to house extensions in Hammersmith and Fulham sets out how the same work is handled across the rest of the authority.
House extensions in Shepherd's Bush are dominated by single-storey rear and side-return additions on W12's victorian and edwardian terraces, post-war estates and, with double-storey and wrap-around schemes where the plot allows. Hammersmith & Fulham Council weighs depth, height and neighbour daylight; many extensions across Shepherd's Bush, White City, Wood Lane, Askew Road fringe are Permitted Development, which we confirm with a Lawful Development Certificate before you build.
The whole spectrum — rear extensions, side returns, wraparounds, double-storey, basement digs. Planning-led design with detailed technical phase, ideal for victorian and edwardian terraces, post-war estates and typical of Shepherd's Bush.
Across Shepherd's Bush, White City, Wood Lane, Askew Road fringe in W12, the dominant property is victorian and edwardian terraces, post-war estates and major new-build around white city, with the bbc and westfield-led regeneration. That stock shapes what house extension drawings looks like here: the right approach for a period terrace differs from a mansion-block flat or a new-build, and Hammersmith & Fulham Council judges each on design quality and neighbour impact. We survey the specific Shepherd's Bush property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the W12 streetscape.

The White City Opportunity Area — Westfield, the BBC site, and Imperial's research campus — has transformed the north of W12 and lifted values across the postcode. For a house project it improves the backdrop; your scheme is still governed by Permitted Development limits and the council's householder policy, which we apply.
Usually yes on the terraces — an L-shaped rear dormer within the volume allowance, confirmed by a Lawful Development Certificate, provided you're not in the Wendell Park conservation area. We check the constraints for your road and draw it for Building Control.
With houses around £800,000-£1.1m and the White City regeneration improving the area, a well-designed rear extension or loft adds family space worth comfortably above the build and drawing cost.
With Shepherd's Bush property at around £450,000 for a flat and £800,000-£1.1m for a house, the professional drawing fee is a small fraction of the value the work adds to W12's victorian and edwardian terraces, post-war estates and.

Almost always. Any structural work behind house extension drawings in Shepherd's Bush — new openings, steel beams, loft floors, foundations — needs Building Regulations approval covering structure (Part A), fire escape (Part B) and insulation (Part L), submitted to Hammersmith & Fulham Council Building Control or an approved inspector. On W12's typically terraced and semi-detached stock, a Party Wall notice to adjoining neighbours is normally required before the steelwork. We coordinate both as part of the Complete package.
In value terms, yes. The bigger risk is an unapproved or non-compliant scheme — which is why council-ready drawings and a clean Building Control sign-off matter on W12 homes.
