Kitchen Extensions
A kitchen extension turns the kitchen into the heart of the home: a bright, open-plan space for cooking, eating and gathering. MVV designs and builds kitchen extensions across South West, West and South East London, shaping a space that suits how you live while making the most of your property and the natural light.


Our approach
We work closely with you from first concept to final finish, so your kitchen extension lifts everyday life and unlocks the potential of the whole ground floor. With careful craftsmanship and meticulous project management, we deliver a kitchen you will love, on time and on budget.
How much does a kitchen extension cost in London?
From projects we priced in August 2026, all ex VAT: the extension itself starts at around £80,000 for building the new space, roughly £2,400 per square metre, with £2,400 to £2,800 per square metre a realistic inner London range for new above ground space at a high standard. The kitchen fit out is priced separately: a kitchen diner refit starts from around £27,000 before appliance upgrades beyond the agreed specification. A two storey side return we priced recently, adding a kitchen extension with a bedroom and shower room above, came to around £188,000. Because the building work and the kitchen are two different decisions, the instant estimator prices yours from your own description rather than quoting an average. Figures are indicative, from real London projects.
How long the work takes
An open-plan kitchen extension typically takes around three to six months, covering planning, construction and finishing, depending on the scale and complexity of the scheme.
Planning permission
Many kitchen extensions need planning permission, while some fall under permitted development depending on the borough. We manage the application for you and submit the documentation your local authority requires for a smooth approval.
Choosing the right design
Our designers work with you so the new kitchen feels like a natural extension of the house. We focus on flow, light and the connection to the garden, creating an open-plan space that genuinely improves daily life.
Adding value to your property
A well-designed open-plan kitchen extension is one of the most appealing improvements to a London home and can add real value, because a bright, sociable kitchen is high on most buyers' wish lists.
