Kitchen Extensions: What to Consider

Kitchen Extensions: What to Consider

Kitchens are the centrepiece of any home. They’re where we retreat to after a hard days work, where we entertain friends and family and where we burn all of our toast, despite getting the toaster settings right just yesterday.

Put simply, our kitchens are important. It’s why so many of us are forever eyeing that big kitchen renovation, and why yet more of us want to truly revolutionise our living experience and extend our kitchens outwards.

The benefits of a kitchen extension are obvious; more space, light and a blank canvas on which to create something that is both functional and beautiful, but what do you need to consider before you take the plunge? Here’s our essential guide:


What does your new kitchen need?

Before you get to work on any of the difficult stuff, you need to get to grips with exactly what your requirements are for your new kitchen. You’ll probably have a pretty good idea of what you want but writing it out will help you determine how much space you’ll need.

You may want an island unit, walk-in larder and range cooker. Perhaps you’ll want an American-style fridge-freezer, separate utility area and bi-folding doors. You may even want all of the above! Make a big list of the essential design elements of your kitchen extension now and it’ll help you significantly when you’re coming to plan your build.


What will your extension cost?

Extensions demand quite a bit of construction work, and that’s before you get to the cost of constructing your kitchen, purchasing appliances and more. Prices will vary quite significantly throughout the year and based on location (expect to pay a London premium if you’re in the capital).

Nevertheless, here’s what your extension will cost:


  • Construction work will cost between £1,100 and £3,000+ per m².


  • Your kitchen design and installation will cost between £15 and £100 per m², depending on specification.


  • Flooring will cost between £25 and £125 per m².


  • Finishing costs (painting and tiling) will run you between £50 and £100 per m² if you use a contractor but can be reduced significantly if you’re willing to carry out the work yourself.


You’ll also need to factor in the costs associated with seeking planning permission for the extension, which will vary based on your design and where you live. It’s worth seeing whether your extension falls under ‘permitted development’, as this can remove your need to apply for planning permission.

With these costs factored in, you can revisit your original list of kitchen extension requirements and make any tweaks you need to in order to get your kitchen within budget.
