Create more space. Flood your home with natural light. Elevate everyday living.

A kitchen extension isn’t just an addition – it’s a transformation. At Kesseler, we design and craft bespoke kitchens that become the centrepiece of extraordinary extensions across the UK.

From elegant orangery kitchen extensions to open-plan kitchen diners, our team works alongside architects, developers and private
homeowners to design kitchens that maximise space, flow and style.

Whether you’re dreaming of a contemporary plus room, a traditional kitchen conservatory extension, or a rear kitchen extension
that opens onto your garden, we help shape spaces that bring the whole home together.

Why Extend Your Kitchen

The kitchen has become more than just a place to cook – it’s the heart of modern living. A kitchen extension allows you to reshape your home around the way you live now, not the way your house was originally built.

From semi-detached homes in cities to country cottages and contemporary self-builds, a well-considered kitchen extension offers countless benefits:

Live better – Open-plan layouts with space to cook, dine, relax and entertain
Add value – One of the most desirable renovations for boosting property resale
Connect to nature – Maximise natural light and flow to the garden
Future-proof your home – Adapt your layout for family growth or hybrid working

We’ve helped hundreds of clients unlock their home’s hidden potential without the need to move.

Kitchen Extension Ideas to Inspire Your Project

Need ideas for your own project? Here are some of the most popular kitchen extension types we design for clients across the UK:

REAR KITCHEN EXTENSIONS

A timeless option, ideal for period or terraced homes. Rear extensions let you add width and depth to your ground floor layout. Think floorto-ceiling glazing, skylights and minimal sightlines to create a seamless connection to the garden.

KITCHEN DINER EXTENSION IDEAS

Bring everyone together in one beautiful, open-plan space. Kitchen diner extensions are perfect for families and entertaining – combining cooking, eating and relaxing zones in a single flowing layout. These spaces often include islands, statement lighting and large sliding doors to open up the home.

Small Kitchen Extensions for Semi-Detached Homes

Even modest spaces can benefit from smart design. For semi-detached homes, we often design wraparound kitchen extensions or compact rear additions that dramatically improve functionality without overwhelming the property. Zoning is key – think vertical storage, built-in seating and adaptable lighting.

Plus Rooms and Side Return Extensions

Looking to make use of a side alley or unused exterior space? A plus room or side return extension adds valuable square footage and unlocks new potential. These often become beautifully lit kitchen diners with rooflights and bespoke cabinetry designed around the awkward angles.

Orangery & Conservatory Kitchen Extensions

An orangery kitchen extension creates architectural drama and elegance, with a partially glazed roof that floods the space with light. Similarly, conservatory kitchen extensions offer a brighter, more garden-focused atmosphere – perfect for those wanting a strong connection to the outdoors.

What to Consider When Planning a Kitchen Extension

A successful kitchen extension balances architecture and interior design from the very beginning. Here are a few expert pointers to get started:

Plan your layout early – Decide where appliances, windows and walkways will go as early as possible in the process
Work with trusted professionals – It’s important to get quotes from at least three different builders and choose one who understands your vision
Set your budget – Account for building work, kitchen cabinetry, appliances, flooring and finishes
Consider materials and finishes – Use colour, texture and premium details to elevate the space and ensure timeless appeal
