Kitchen Extension Cost in Pimlico: 2026 Price Guide

Pimlico - where a graceful grid of white stucco terraces and garden squares laid out by Thomas Cubitt, alongside the post-war Churchill Gardens estate - sees a steady stream of rear kitchen extensions, and for good reason: it's often the single change that makes the biggest difference to how a house actually lives day to day.

Typical costs

• Small extension (up to 15m²): roughly £30,000-£45,000
• Medium extension (15-25m²): roughly £45,000-£70,000
• Larger or wraparound extension (25m²+): £70,000 upwards

These figures are a guide, not a quote - they cover building work, a standard fit-out, and typical finishes. Bifold or sliding doors, roof lanterns, underfloor heating and a higher-spec kitchen will all add to the total.

What affects the price locally

In Pimlico, the biggest local factor is usually access. Many streets are close terraces with no side access, which means materials have to be carried through the house and skips have to sit on the road - both of which builders will price in. Properties within the Pimlico conservation area, designated in 1968, plus the Churchill Gardens and Lillington and Longmoore Gardens conservation areas sometimes face tighter controls on matching brick, roofline and window styles to the existing building, which can add to material costs even for a rear extension that doesn't need planning permission.

Foundations matter too - the Victorian and Edwardian housing near St George's Square was typically built on shallower footings than current standards expect, so a structural engineer often specifies extra depth that a modern property simply wouldn't need.

Do you need planning permission?

Permitted development covers a lot of single-storey rear extensions, but not without limits, and those limits bite harder on terraced and semi-detached houses than detached ones. Inside Pimlico's conservation areas, expect those rights to be trimmed back further still - check with the City of Westminster's planning department, or a builder who already works locally, before finalising a design.
