Why Choose Reltic Extend in Barnet?
At Reltic Extend, we don’t just put bricks and mortar together – we design and deliver homes that truly reflect the way you want to live. An extension isn’t simply about adding square footage; it’s about creating spaces where family life feels easier, where mornings run smoothly, and evenings are spent in comfort.
Homeowners in Barnet trust us because we take time to understand not only their property, but also their lifestyle. Whether it’s designing a kitchen that becomes the heart of the home, adding a double-storey extension to give children their own space, or blending a new structure seamlessly with the charm of a Victorian terrace, every detail is carefully considered.
Here’s what makes us different:
Specialist Expertise
We focus solely on extensions – rear extensions, side-returns, wraparounds, kitchen extensions, and double-storey builds. This means we bring deep knowledge and proven methods to every Barnet project.

Barnet Council has clear guidelines on what can and cannot be built. Our planning team handles all drawings, permissions, and building regulations, removing the stress from your shoulders.
