Question 1

How much does a side-return kitchen extension cost on a W11 Notting Hill terrace?

Accepted Answer

A single-storey side-return on a Notting Hill terrace — taking in the structural opening, the new roof structure, rear or overhead glazing, and a new fitted kitchen — generally falls in the range of £90,000 to £165,000. Houses where the party wall coincides with the side boundary add party-wall surveyor costs, and the Pembridge and Ladbroke conservation areas restrict glazing types and external materials, both of which can push the specification higher. Planning, party-wall and build costs are each shown as separate lines in our quote so the total is transparent before any commitment is made.

Question 2

Do extensions in Notting Hill's conservation areas need full planning permission rather than prior approval (W11)?

Accepted Answer

Across most of W11, Article 4 directions have removed the standard permitted development rights that would allow smaller extensions without a planning application. The practical effect is that a rear or side addition on a Notting Hill terrace almost always requires a full RBKC planning application. Key constraints are external materials, roof pitch, and the extension's relationship to the rear garden boundary. We check the conservation designation for your specific street at the site visit and give you a straight, honest assessment of likely approval prospects before any application fees are spent.

Question 3

What does a full renovation of a period conversion flat in Notting Hill cost (W11)?

Accepted Answer

A complete refit of a Victorian conversion flat in W11 — stripping back the structure, replastering, full rewire, full replumb, then a new kitchen, new bathroom, and a finished floor and decoration throughout — typically runs between £45,000 and £90,000 depending on the floor area and the finish level specified. Leasehold flats require a written licence for alterations from the freeholder before structural or services changes begin. We include the licence-of-alteration process in the project plan and issue an itemised quote broken down by trade on the day of the site visit.
