Question 1

What does a loft conversion on a W5 or W13 Edwardian detached house typically cost in Ealing?

Accepted Answer

A hip-to-gable conversion with a rear dormer on a four-bedroom Edwardian detached in W5 — creating a full double bedroom, en-suite and landing — generally sits between £65,000 and £115,000. Ridge height on these properties is usually generous, and the gable end can be built out without touching the footprint below. Where a heating upgrade is also needed, that element is managed through a Gas Safe registered partner and priced separately. Our same-day itemised quote at the site visit breaks structure, roofing, dormer, internal fit-out and finishes into individual line items so you can adjust scope with clear numbers in hand.

Question 2

How does Ealing Council's Walpole Park conservation area affect what I can build in W5?

Accepted Answer

The conservation designation around Walpole Park carries Article 4 directions on certain streets, removing permitted development rights that would otherwise apply automatically. This means a rear extension or loft alteration that would be straightforward in most W5 postcodes may need a full householder application rather than a prior-approval certificate. The practical effect is less about whether the project is possible and more about the consent route and the choice of external materials — reclaimed brickwork to match the original fabric, for instance, rather than a contrasting render. We cross-check the exact designation for your address at the survey stage and clarify the planning pathway before any design work is commissioned.

Question 3

Is a side-return extension viable on the narrower terraced streets of W13 near Ealing Broadway?

Accepted Answer

The terraced roads feeding into the W13 side of Ealing — between the Broadway and the Hanwell boundary — do include narrower plots where the side passage measures under a metre, which makes the structural question around spanning steels more involved than on the wider W5 avenues. That said, many W13 side-returns have been successfully built: the key is engineering the steel span correctly and choosing a glazed roof or lantern that maximises light without increasing load. A combined side-return and rear extension on a W13 terrace, including a full kitchen replacement, typically runs £55,000 to £105,000 depending on depth, glazing spec and kitchen tier. Party Wall Act notices on shared boundaries are handled as part of the build programme.
