The Complete Guide to Modern, Eco-friendly Kitchen Extensions

This guide will take you through the complete process of planning and implementing a kitchen extension project, with the added advantage of making your home more sustainable.

Section 1: The Need for Kitchen Extensions in Modern Lifestyles

Our fast-paced modern lifestyles necessitate homes that mirror this dynamism and provide spaces that are comfortable, efficient, and well-integrated. Traditional housing often doesn’t offer these attributes – specifically in the kitchen area – leading many homeowners to consider the prospect of kitchen extensions. Given the kitchen’s central role in a home, improving it can enhance your entire living space’s overall appeal and functionality.

Section 2: Common Kitchen Extension Options

There are several ways to expand a kitchen based on the existing layout and structure of your home. Some popular methods include creating an open-plan kitchen by removing internal walls, extending into the side return, extending to the rear, or creating a double-height space.

For homes with Victorian or Georgian architecture featuring a lower ground and raised ground floor layout, consider the practicality and accessibility of your kitchen. For instance, you might choose to locate the kitchen on the raised ground floor for better street access at the front or on the lower ground floor for easy access to the garden at the rear.

Section 3: The Financial Implications of Kitchen Extensions

Kitchen extensions, particularly in London and the South East, typically cost between £2,200-3,100 per square metre, but prices can fluctuate depending on the complexity and quality of the kitchen fit-out. You can expect a simple kitchen fit-out, including appliances and services, to start at around £17,000, with premium options costing upwards of £65,000.

Section 4: Outline Design Considerations for Your Kitchen Extension

Before embarking on your kitchen extension, it’s essential to plan. Think about what works well in your current kitchen and what doesn’t, and consider how you and your family move within this space.

Will a single bank of units be sufficient, or would a galley kitchen be more practical? How many people typically use the kitchen at once? Would a peninsula or island work well in your new space? These are all important factors to ponder when conceptualising your new kitchen design.

Section 5: Detailed Design Considerations

On top of the primary outline design considerations, there are finer details to take into account as well. These involve storage solutions, appliance placement, and the overall aesthetics of your new kitchen.

You might consider electrical sockets in a cupboard to hide appliances or integrating storage devices to make awkward corner cupboards easier to use. Perhaps you require built-in wine storage or charging points for electronics. Tailoring these details to your specific needs and preferences can greatly enhance the functionality and enjoyment of your new kitchen.

Section 6: Choosing the Right Installer for Your Kitchen Extension

There are numerous options when it comes to installing your kitchen extension. From off-the-shelf options like B&Q, Wickes, Howdens, IKEA, and online companies such as diy-kitchens.com to specialist kitchen companies like deVol and Bulthaup, there’s a choice for every budget and requirement.

If you’re seeking a truly unique kitchen design, a bespoke solution from a skilled joiner might be the best route. They can work to your exact requirements, ensuring your new kitchen fits seamlessly with the rest of your home.

Section 7: Deciding on Appliances

Appliances play a crucial role in the functionality and efficiency of your kitchen. Whether you’re reusing existing appliances or purchasing new ones, it’s vital to choose options that align with your lifestyle, space, and energy consumption goals.

From ovens to hobs, fridges to freezers, and even boiling water taps or drawer-type dishwashers, appliances come in all shapes and sizes. Always consider the energy rating of your chosen appliances as this can significantly affect your running costs and overall home’s energy efficiency.

Section 8: Worktops, Splashbacks and Cupboard Finishes

When it comes to worktops, splashbacks and cupboard finishes, you’re spoiled for choice. There are various materials available in a wide range of colours, textures, and prices. From laminates to solid woods, composite materials, and even concrete or terrazzo, the right choice will hinge on your aesthetic preferences, practical needs, and budget.

Cupboard finishes also offer a wide array of options, including laminated plywood, veneered plywood, or a sprayed lacquered finish. The colours, materials, and even the handles you choose for your cupboards can dramatically impact the overall look and feel of your new kitchen.

Section 9: Floor Finishes and Other Considerations

The floor finish is an important aspect of any kitchen design. It should be durable, resistant to stains, and ideally extend throughout the kitchen, dining, and living areas for a unified look. Options range from timber and tiles to stone to polished concrete and natural linoleum.

Additional elements to consider include lighting, ventilation, heating, and furniture. You might wish to include dimmable mood lighting, ensure adequate ventilation, opt for underfloor heating, and select furniture that complements your new kitchen.
