Extension and kitchen project guide
An extension plus kitchen project combines extra floor area with a redesigned cooking and living space, often to create a larger family hub, better circulation, and stronger connection to the garden. You usually need an architect or other building professional when the layout changes, structural work is involved, or planning and building rules must be coordinated. The outcome is driven by the quality of the brief, the existing building constraints, the level of finish, and how early structure, services, and lighting are resolved.

— Questions
Frequently asked questions
How much does an extension with a kitchen usually cost?
Costs vary widely with size, structure, finishes, and how much of the existing home must be altered. The biggest drivers are foundations, steelwork, glazing, kitchen specification, and service relocations, so a professional quote is the only reliable way to compare options.
How long does this kind of project take?
A typical project can take several months from first survey to completion, and longer if design changes or approvals are involved. The construction stage itself is often only part of the overall timeline, with design and quoting taking meaningful time beforehand.
Do I need permits for an extension and kitchen remodel?
Often, yes, especially when the extension changes the building footprint, height, structure, or appearance. Even when formal planning approval is not required, building regulations and local constraints can still apply, so it is wise to check early with the right professional.
