Home Extensions in North London
At Reltic Extend, we help homeowners across North London unlock the hidden potential in their properties. From elegant Victorian terraces to spacious family homes and ground floor flats, we design and build extensions that add space, light, and value.
In busy parts of North London, moving house isn’t always the best option. It can be stressful, expensive, and may even take you away from the community you love. That’s why a home extension is such a smart choice – it lets you stay where you are while creating the room your family needs. A tailored rear extension, side extension, or wraparound extension can give you everything from a bigger kitchen to an extra bedroom, designed with your lifestyle in mind.
From Muswell Hill to Barnet, Islington to Crouch End, we’ve helped families across North London transform their homes. Whether it’s a bright open-plan kitchen or a multi-functional living space, our approach is always simple, transparent, and tailored to you.

Designed Around You
We believe the best extensions are the ones that feel like a natural part of your home. That’s why we start with your ideas – how you live now, and how you’d like your home to work in the future.
Perhaps you want a generous kitchen extension where the family can cook and eat together. Maybe you need more bedrooms with a double-storey extension. Or you might dream of a layout that connects seamlessly to the garden through a glazed rear extension. Whatever you’re looking for, we’ll design and build a solution that feels made just for you.
With flexible designs and a clear design & build process, we keep you in control at every stage while making the whole experience enjoyable.
Why Extend Your Home in North London?
A well-planned extension is one of the most rewarding home improvements you can make. It doesn’t just add space – it changes the way you live. From creating a modern kitchen-diner to designing a home office or playroom, extensions give you freedom and flexibility.
For North London homeowners, extensions are particularly valuable. Properties here are in high demand, and adding extra living space can increase your home’s value by as much as 20%. A wraparound extension can transform the ground floor of a terrace, while a side return can turn a narrow alley into a bright and usable room.
