Will Ealing Council approve a mansard loft?

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.

What's the ideal mansard pitch for Ealing?

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.

Can I have a mansard if my neighbours don't in Ealing?

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.

How much does a mansard cost in Ealing?

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.

How much headroom does a mansard give me in Ealing?

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.
