Question 1

What does a side-return extension with a fitted kitchen cost in Chiswick, W4?

Accepted Answer

A single-storey side-return on a W4 Victorian terrace — structural opening, new roof section (pitched or flat), full-width glazing, and a fitted kitchen — typically falls between £72,000 and £118,000. Glazing grade, kitchen specification, and whether the rear wall is also opened up push the figure across that range. Inside the Bedford Park conservation area, external materials and joinery details are governed by Hounslow's design guidance for the area, which adds both time and cost; we flag that as a separate line in the quote. The written breakdown is in your hands on the day we come out.

Question 2

Do Article 4 directions in Bedford Park remove my permitted-development rights for an extension (W4)?

Accepted Answer

Yes. The Article 4 direction attached to the Bedford Park conservation area withdraws the permitted-development rights that W4 homeowners on streets outside it would normally use. Any extension, roof alteration, window replacement or change to external materials on a Bedford Park property requires a full planning application to Hounslow. The council's design guidance for the area expects works to reinforce the original Arts and Crafts character in proportions, materials and joinery detailing. On streets in W4 that fall outside the designation — the majority of Chiswick — standard permitted-development rules apply and rear extensions under 3 m on a semi go through without a full application.

Question 3

Beyond the side-return, what renovation projects come up most often on Chiswick's Victorian and Edwardian stock?

Accepted Answer

After the side-return, dormer loft conversions are the next most frequent request — converting a basic roof void into a bedroom with en suite and bringing usable square footage up to the ridge. Whole-house programmes that combine structural work, a kitchen refit, one or two bathroom refits, replumbing and rewiring into a single coordinated schedule are common on properties that have not been touched in twenty years. Properties near Chiswick House occasionally call for restoration detail: repairing original sash windows, reinstating period cornicing, refinishing original timber floors.
