Question 1

What is the cost of a rear extension and kitchen refit on an SW17 terrace in Tooting?

Accepted Answer

On a mid-Victorian or Edwardian terrace in Tooting SW17, combining a single-storey rear addition with a full kitchen refit — foundations, structural steels, roof, rear glazing, electrics, plumbing and fitted kitchen — typically runs between £54,000 and £92,000. The footprint of the extension and the kitchen specification move the number most; a compact lean-to with mid-range units sits lower, a wide-open plan with bi-fold doors and a bespoke fitted kitchen higher. Heating work is carried out by our Gas Safe registered partner. Every trade is priced as a separate line on the quote.

Question 2

Will my Tooting terrace extension fall under permitted development or need a full planning application in SW17?

Accepted Answer

A ground-floor rear addition on a standard SW17 terrace frequently qualifies as permitted development — meaning no planning application — provided the depth stays within limits, the ridge sits below the main roof, and no more than half the original garden is covered. Streets within the Tooting Bec Conservation Area may have had certain permitted development rights removed by an Article 4 direction, which would require a formal consent even for an otherwise straightforward extension. We check your specific street at the survey, recommend a lawful development certificate where it protects resale value, and submit a full application where the design or designation demands one.

Question 3

Do conservation area designations near Tooting Bec affect internal renovation work in SW17?

Accepted Answer

No — Article 4 directions and conservation area controls apply to external changes to a building's appearance, not to work carried out entirely inside. A complete kitchen refit, bathroom refit, structural alteration or full interior renovation is unaffected by any heritage designation on your street. We note the designation at the survey so you understand precisely which elements of a project need external consent and which proceed freely, and we manage any required applications as a clearly costed item in the programme.
