What is a kitchen extension?

A kitchen extension is an extra area of space added to your existing kitchen, which typically requires building work. It will make your kitchen larger, and will often add value to your home.

Is a kitchen extension right for your home?

A kitchen extension can open up smaller spaces to make a multi-functional room, like a kitchen-diner for the whole family to enjoy. An extension can also create separate areas, such as a utility room for doing the laundry.

Is there enough space for my extension?

The side of the house, the garden or a neighbouring room are all great spaces for a kitchen extension. Any structural changes will need planning permission checked by your builder.

How much will a kitchen extension cost?

Kitchen extensions are usually priced per square metre, so larger extensions will cost more. Set a budget for building work, and have a contingency for other potential costs, like a party wall settlement or site insurance. Remember to budget for furniture and decor too.
