    Planning a Tooting extension or loft

    Tooting's terraced and semi-detached homes often have strong potential for rear, side-return and roof alterations. The key is to check the original building, neighbouring precedents and structural condition before deciding which extra space offers the best value for the household.

    What to check before choosing a contractor

    • Check the exact conservation and planning position rather than relying only on nearby precedents.
    • Resolve shared walls, drains and restricted access early for terraced-house extensions.
    • Compare rooflight and dormer loft options using usable floor area, not just the footprint shown on a plan.

    Tooting: nearby work and Totterdown Fields

    No finished Tooting job on the site yet. The closest we can show you are our Earlsfield side return and our Wimbledon whole-house renovation.

    Totterdown Fields

    Totterdown Fields was the London County Council's first cottage estate, built between 1901 and 1911, with about 1,244 houses. It's been a conservation area since 1978 and has an Article 4 Direction. Windows and doors you can see from the street, re-roofing in a different material, porches, front hardstanding and front walls all need planning permission. If you live there, a like-for-like approach is usually the safe starting point.

    Tooting is Wandsworth borough, so skips and scaffold on the road need council licences. The Wandsworth Article 4 guide covers the estate in more detail.

    Common Questions

    Many extensions fall under permitted development. Properties in the Tooting Bec Gardens Conservation Area may need planning permission from Wandsworth Council. We check this at our free site visit, then give you a fixed-price quote.

    A typical loft conversion with us, a rear dormer with an en-suite, costs about £80,000–£90,000 to build, and a typical kitchen or side return extension about £90,000–£100,000 (build price; kitchen units, flooring and other second-fix items are supplied by you). Both exclude VAT and professional fees. Prices are the same across the boroughs we cover, though access and logistics can affect the final figure. You get a fixed quote after a site visit.

    Loft conversions: around 13-15 weeks as a realistic target; larger or complex schemes take longer; written programme after survey and design. Kitchen and side return extensions: around 13 weeks on site. Detailed timeline provided before work begins.
