Why Reltic Extend is the Right Choice for Your Kitchen Extension
A bigger kitchen isn’t just about having more room to cook – it’s about creating a space where the whole family can come together. Studies show that a well-designed kitchen can add real value to your home, which is why so many Londoners choose to invest in kitchen extensions. From cosy kitchen diners to large open-plan layouts, the possibilities are endless.
The extension that suits you best will depend on your home and lifestyle. For terraced houses, a rear kitchen extension is often the ideal option, while side return extensions are a clever way to turn wasted space into something useful and bright. Whatever your property type, we’ll work with you to design a kitchen that feels tailored to your home.
With Reltic Extend, you’ll enjoy:
- A personal design service with full planning support
- Smart upgrades like skylights, roof lanterns, and sliding or bi-folding doors

If you feel like your home no longer works for your family but you’d rather not move, a kitchen extension could be the perfect solution. Whether you’ve always pictured a modern space with a central island or a light-filled open-plan area for entertaining, we’ll help you create a home that truly fits the way you live.

Rear Kitchen Extension
A rear kitchen extension is one of the most popular choices for London homes. By extending your property out into the garden, you can create a spacious, open-plan kitchen and dining area filled with natural light. Features like skylights, roof lanterns, and wide bi-folding doors bring the outdoors in, making this design perfect for entertaining, family dinners, and everyday living. A rear extension works particularly well in terraced and semi-detached houses, especially across North London, where homeowners want to maximise space without compromising their garden.
Side Return Kitchen Extension
A side return kitchen extension makes clever use of the narrow strip of land that often runs alongside London homes. By transforming this unused alley, you can significantly widen your kitchen, creating a brighter and more practical layout. With skylights or glass roofing, the new space is flooded with natural light, giving your home a modern, open feel. This option is especially popular in Victorian and Edwardian terraces across South London, where space is limited but the impact can be huge. It’s a cost-effective way to add value to your property while making your kitchen a true family hub.
Wrap-Around Kitchen Extension
For homeowners seeking the ultimate transformation, a wrap-around kitchen extension offers space and flexibility. By combining a rear and side return extension, you create a large, open-plan layout that can include a kitchen island, dining table, and family seating area. With glass doors, skylights, and modern finishes, the space feels bright and contemporary, ideal for entertaining or everyday family life. This style suits London homes with gardens and side access, giving you a versatile design that works for both traditional and modern properties while boosting overall value.
Small Kitchen
Extension
A small kitchen extension is proof that you don’t need a huge amount of space to make a big impact. By cleverly extending just a few metres, you can completely change the look and feel of your home. Popular in London terraces and smaller properties, this type of extension is ideal for creating a bright kitchen diner, adding room for a breakfast bar, or improving storage and layout. With thoughtful design, skylights, and modern finishes, even compact spaces feel spacious and inviting. It’s a cost-effective way to increase property value while making your kitchen the true heart of the home.
Popular Features for Your Double Storey Extension
Bi-Folding Doors
Bi-fold doors create a seamless connection between your kitchen and garden. They add natural light, space, and a stylish modern finish that transforms everyday living.
Utility Room
A utility room keeps laundry, storage, and everyday chores separate from your main kitchen. It’s a practical addition that brings both organisation and convenience to your home.
Natural Light Features
Bring more daylight into your kitchen extension with skylights or roof lanterns. Bright, airy spaces feel larger, more welcoming, and perfect for modern family living.
Our Process
At Reltic Extend, we provide a complete service for kitchen extensions in London – from the first consultation right through to the finishing details. Our aim is to make the whole journey smooth, transparent, and enjoyable for every homeowner.
Every successful project starts with a conversation. We’ll arrange a friendly site visit to understand your goals, assess your property, and explore what’s possible within your budget. This is your opportunity to share ideas for your new kitchen extension, whether it’s a side return, rear extension, wrap-around, or small kitchen extension. We’ll also discuss practicalities like timelines, planning permission, and potential layouts.
Once we’ve agreed on a concept, our architects prepare detailed plans tailored to your property. We’ll also handle the necessary planning applications, building regulations approval, and even party wall agreements if required. Our design team focuses on creating a kitchen extension that balances natural light, functionality, and style – with options such as skylights, bi-fold doors, utility rooms, or a central kitchen island.
Our skilled construction team brings your kitchen extension to life. From foundations and structural work through to electrics, plumbing, and roofing, we manage every aspect of the build with precision. We use trusted materials, follow strict building regulations, and keep you updated throughout. Most kitchen extensions in London take between 8 and 16 weeks to build, depending on size and complexity.
The final stage is about making your kitchen extension truly yours. We’ll install fixtures, fittings, flooring, lighting, and décor to the highest standard, ensuring every detail is finished perfectly. Whether you’ve chosen an open-plan layout with a dining area or a compact design with smart storage, we’ll deliver a polished result that enhances your lifestyle and adds value to your home.
A kitchen extension is one of the best ways to add space, light, and value to your home – but most importantly, it creates a place your family will love for years to come. At Reltic Extend, we take care of everything from planning to finishing touches, so all you need to do is imagine the possibilities.
