Ealing's Edwardian terrace stock is extensive, covering much of West Ealing, Hanwell, and Acton. The borough's Residential Design Guide addresses mansard roofs with specific guidance on the minimum setback from the front parapet (1m), the maximum permitted front slope angle (70–75 degrees), and the requirement for the mansard to 'read as a roof addition, not a full storey'.
The combination of mansard and rear dormer is common on Edwardian terraces — it maximises the volume created from a single planning application. We designed the two elements as a coherent package: the mansard covering the front half of the roof, the rear dormer spanning the rear half, with a flat roof connection between them.
Ealing's planning officer raised a query about the proposed zinc cladding on the mansard front slope. The character appraisal for this area references grey slate as the traditional roof material — we provided precedent photographs of zinc-clad mansards on neighbouring streets that had received approval, and the officer accepted this as sufficient precedent.
Eleven weeks to determination. Ealing is slower than the outer borough average but faster than the inner-London norm for conservation area applications. The client's builder started on site 6 weeks after the planning decision, completing in 13 weeks with a handover just before the summer school holidays — exactly as planned.
