Home Extensions Brentford
Create the Space Your Brentford Home Deserves
Brentford, with its riverside charm and blend of period terraces, industrial conversions, and new developments, has become one of West London’s most exciting neighbourhoods. While the area offers character and fantastic transport links, many homes here still have compact kitchens, small living rooms, or layouts that don’t suit today’s preference for light-filled, open-plan living.
At Reltic Extend, we specialise in delivering bespoke home extensions in Brentford that transform outdated layouts into modern, flowing spaces. Whether you want a stylish rear extension to open your home to the garden, a clever side return extension to make use of unused space, or a double storey extension for bedrooms and offices, our designs are tailored to your lifestyle and the unique character of Brentford homes.

Here’s what makes us the trusted choice:
Local Expertise
Brentford homes range from Victorian terraces and riverside cottages to modern apartments. We design extensions that respect property character while introducing contemporary features like skylights, glass doors, and energy-efficient insulation.
Planning Confidence
Hounslow Council applies specific guidelines for extensions, particularly along conservation areas and riverside settings. Our planning team prepares professional drawings, design statements, and applications to ensure smooth approvals.
Lifestyle-First Design
We go beyond adding space – we create homes built around your lifestyle. A kitchen extension for family dining, a wraparound extension to open up your ground floor, or a rear extension to bring in light – every design is tailored to you.

No one likes financial surprises. With our Cost Calculator, you’ll get a clear, upfront estimate. We believe in honest, transparent pricing with no hidden extras.
Digital Previews
Our Design & Build 2.0 approach allows you to see your extension digitally in 3D before construction starts. You’ll know exactly how your home will look and feel before building begins.
