Question 1

How much does a single-storey rear extension with a new kitchen cost in Maidenhead (SL6)?

Accepted Answer

On a typical SL6 terraced or semi-detached house, combining a single-storey rear extension with a fully fitted kitchen generally runs from £54,000 to £98,000. The structural shell, glazing package, and kitchen specification each pull the figure in different directions: bifold or roof-light glazing adds to the shell cost, and a high-specification kitchen with stone worksurfaces costs considerably more than a mid-range suite. For the larger detached homes in the outer SL6 area near Bray or Cookham, the extension itself can be deeper and the overall programme broader, so budgets in those cases often sit toward the higher end. Every element is priced as a separate line item on the day of the site visit.

Question 2

Do I need planning permission for a rear extension on my house in Maidenhead (SL6)?

Accepted Answer

Most single-storey rear extensions on SL6 houses qualify as permitted development: up to four metres deep on a detached property or three metres on a terrace or semi, subject to height and material constraints set by the Royal Borough of Windsor and Maidenhead. Larger detached homes toward Cookham and Bray can sometimes qualify for the householder prior-approval route, allowing up to eight metres depth. The exceptions are properties within one of the borough's conservation areas or where an Article 4 direction has removed permitted-development rights — both of which require a full planning application. We verify the applicable planning route at the site visit, before extension costs are finalised.

Question 3

Is a loft conversion a good option on a Maidenhead (SL6) terrace near the Elizabeth line?

Accepted Answer

The Victorian and Edwardian terraces concentrated around Maidenhead town centre and the railway station are well suited to a rear dormer loft conversion: rooflines are typically gable-ended, headroom is adequate, and a rear dormer almost always qualifies as permitted development. The result is usually a double bedroom and an en-suite bathroom — a meaningful addition without altering the house's footprint or requiring any garden space. On larger post-war detached houses further into SL6, a hip-to-gable conversion maximises the usable floor area at roof level more effectively. With direct Elizabeth line services into central London, the uplift in usable and saleable space from a loft conversion in SL6 is one of the stronger cases for the investment.
