Direct answers to the questions Ealing homeowners ask every week about mansard roof extensions.
Start a free quote →Mansards in Ealing are less common historically — Ealing Council considers each application on its merits. Rear mansards on suitable terraced or semi-detached properties, matching the roofscape, have a reasonable approval rate with the right design and supporting heritage commentary where relevant.
A 70° front slope is typical for Ealing mansards — steep enough to maximise floor area while reading as a roof rather than a full additional storey. Front dormers should be small and symmetrical. Ealing Council's design guide (where published) takes precedence on detail.
Often yes, but Ealing Council favours applications supported by wider street precedents. Where mansards already exist nearby in Ealing, approval is far more likely. We review street precedents at the feasibility stage.
Our architectural fees for a Ealing mansard start at £1,575 (planning + building regs + structural + heritage statement). Typical Ealing build costs are £90,000–£150,000 depending on size, complexity and access.
Full-height — typically 2.3–2.5m ceiling from the new floor. Unlike a dormer, which gives partial head height, a mansard provides a complete additional storey within Ealing's victorian and Edwardian villas in Ealing central terraced context.
We cover all Ealing postcodes — {postcodes} — and have submitted mansard applications across the borough. Our heritage statement and design-and-access statement are included in every mansard package.
Ealing's victorian and Edwardian villas in Ealing central terraced stock is the natural context for mansard extensions — they were originally designed for Victorian and Edwardian rows. Feasibility depends on street precedent, conservation area status and party wall implications. We assess all three at the free site visit.
A mansard adds a full upper storey — typically 35–45m² of usable floor space. In Ealing this often converts a 3-bed house to 4 or 5 beds. The steep front slope (70°) and flat top read as a roof, not a full floor, which is why Ealing Council accepts them more readily than a simple box extension.
