Small Kitchen Extensions: Maximise Space with Smart Design & Expert Plans
Don’t let limited square footage stop you from creating the kitchen you’ve always wanted. With the right design, even a small kitchen extension can completely transform your living space — making it feel bigger, brighter, and better suited to modern life. At Draw Plans, we specialise in small kitchen extension layout plans tailored to homes across Greater London, starting from just £795 + VAT.
In this guide, we’ll explore the best small kitchen extension ideas, what you can expect in terms of cost, and how to design the perfect layout to maximise every inch.
Why Consider a Small Kitchen Extension?
Even a modest extension — just 1.5m to 3m outwards — can make a huge difference in your kitchen’s usability and flow. Whether you're working with a Victorian terrace or a compact semi-detached home, a well-designed small kitchen extension can:
-
Create space for a dining area or kitchen island
-
Improve light and ventilation
-
Increase storage capacity
-
Add value to your property
Best Small Kitchen Extension Ideas
1. Side Return Extension for Narrow Kitchens
A side return kitchen extension is ideal for homes with an unused alley or side passage. It may only add a few square metres, but with the right design, it can significantly enhance the kitchen’s footprint and layout.
Tip: Use rooflights to bring natural light deep into the room and avoid dark corners.
2. Rear Kitchen Extension with Glazing
Extending just 2-3m into your garden can provide the space needed for an open-plan kitchen-diner. This is a popular option for creating a social, family-friendly layout.
Tip: Use floor-to-ceiling glazing or sliding doors to visually open up the space and connect to the garden.
3. Small Kitchen Extensions with Islands or Peninsulas
If you have enough space, a small kitchen island or peninsula can add both worktop and seating space. In smaller kitchens, even a narrow island (60cm wide) can be incredibly functional.
Tip: Make sure you allow at least 1 metre of clearance around the island for comfortable movement.
4. Pocket-Sized Utility Room Addition
Incorporating a compact utility or laundry space into your kitchen extension helps keep your main kitchen clutter-free.
Tip: Use a sliding or pocket door to save space and keep things hidden.
5. Smart Storage Solutions
Built-in shelving, tall cabinets, and concealed storage help keep the kitchen tidy and efficient. Think vertically — use the full wall height to your advantage.
Tip: Opt for handleless cabinetry and integrated appliances for a clean, streamlined look.
Planning the Best Layout for a Small Kitchen Extension
Every inch counts in a small space. Here’s how to approach your small kitchen extension layout plans effectively:
✔ Follow the Working Triangle
Keep the sink, hob, and fridge in close, accessible proximity to one another. This layout principle maximises efficiency and minimises movement when cooking.
✔ Let in the Light
Use rooflights, glazed doors, or internal windows to brighten up your space. Light can make a small kitchen feel more spacious and welcoming.
✔ Create Zones
Even small kitchens benefit from defined zones: cooking, prepping, dining, and storage. Zoning helps with flow and keeps things organised.
✔ Use Sliding or Pocket Doors
Where traditional doors take up too much room, sliding or pocket doors save space and give a modern edge to the design.
✔ Keep It Open Where Possible
Knocking through to create an open-plan living or dining space helps your extension feel bigger than it is.
