A rear dormer is the workhorse loft conversion on W12's terraces in Shepherd's Bush — a box across the rear roof slope adding a double bedroom and bathroom while keeping the front roofline intact for the street. Most rear dormers near Shepherd's Bush, White City, Wood Lane, Askew Road fringe are Permitted Development, which we confirm with Hammersmith & Fulham Council via a Lawful Development Certificate.
London's most popular loft type — the full-width rear dormer. Planning or Permitted Development route assessed for your Shepherd's Bush property, building regulations, structural steelwork and Party Wall notices.
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.

Almost always.

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.
