Question 1

How much should I budget for a ground-floor extension and new kitchen in SW20?

Accepted Answer

Adding a single-storey rear extension and fitting a new kitchen on a Raynes Park property typically falls between £55,000 and £88,000, covering groundworks, structural frame, roofing, glazing, and a full kitchen installation including all associated trades. Victorian terraces closer to the station usually land toward the lower end; larger Edwardian or interwar semis with deeper plots can push the figure higher. Every quote we produce is fully itemised, priced line by line, and handed over on the day we visit.

Question 2

Do dormer loft conversions require planning permission in Raynes Park (SW20)?

Accepted Answer

Rear dormers on most SW20 properties are covered by permitted development rights, requiring no planning application as long as the new structure sits below the ridge by at least 20 centimetres and does not face the public highway. The residential streets of Raynes Park carry no Article 4 direction removing those rights, and no conservation area covers the main housing grid in SW20. Work that raises the overall ridge line, or any dormer visible from the street, will always need a formal application. We check your specific address on the day of the site visit.

Question 3

Which extension type suits the Edwardian and interwar semis in Raynes Park (SW20)?

Accepted Answer

Edwardian and interwar semi-detached properties in SW20 typically have a side return running alongside the original kitchen that is well suited to infill — creating a larger ground-floor footprint without any garden loss. Hip roofs on 1930s properties are also candidates for hip-to-gable conversion, adding a full extra bedroom and en-suite above. We assess the property type, orientation, and available head height at the site visit and advise on which approach delivers the best return for the budget. Neighbouring Wimbledon and New Malden are covered under the same terms.
