Home Extensions Haringey
Create the Space Your Haringey Home Deserves
Haringey is one of North London’s most varied boroughs, with vibrant communities, historic terraces, and leafy residential streets. From Victorian homes in Crouch End to 1930s houses in Muswell Hill and new developments across Tottenham, the area has something for everyone. Yet many properties here weren’t designed with today’s lifestyle in mind – kitchens are small, layouts feel outdated, and growing families often struggle with space.
At Reltic Extend, we deliver bespoke home extensions in Haringey that unlock your home’s true potential. Whether you’re looking for a light-filled rear extension, a clever side return extension to widen your kitchen, or a full double storey extension to add bedrooms and office space, our designs are tailored to your property and lifestyle.

Here’s what makes us the trusted choice:
Local Expertise
Haringey’s housing mix is diverse – Victorian terraces in Stroud Green, Edwardian houses in Muswell Hill, and family homes in Tottenham. We know how to design extensions that respect period character while introducing modern features like skylights, open-plan layouts, and energy-efficient glazing.
Planning Confidence
Haringey Council’s planning rules can be strict, especially for conservation areas around Crouch End, Highgate, and Muswell Hill. Our planning specialists prepare professional applications, drawings, and reports to secure approvals quickly and efficiently, saving you delays and stress.
Lifestyle-First Design
We don’t just add space – we design for modern living. From kitchen extensions for family gatherings, to wraparound builds that create flowing open-plan layouts, every project is designed around how you use your home.
Transparent Costs
Budget certainty is crucial. With our Cost Calculator, you’ll receive a tailored estimate upfront. We believe in honest, transparent pricing with no hidden surprises.
Digital Previews
It’s difficult to imagine a new home from drawings alone. With our Design & Build 2.0 process, you’ll see digital 3D previews of your extension before building starts. That means you can make design decisions with confidence and know exactly what you’re getting.
With Reltic Extend, Haringey homeowners benefit from expert local knowledge, planning support, and bespoke designs that improve both lifestyle and property value.
