Home Extensions Colliers Wood
Smarter Space for Modern Living in Colliers Wood
Colliers Wood is a lively South West London neighbourhood with a mix of Victorian terraces, Edwardian homes, and new developments along the River Wandle. While the area has excellent transport links and a growing community, many properties were built with smaller kitchens, closed-off rooms, and layouts that don’t match today’s demand for open, modern living.
At Reltic Extend, we specialise in designing and building bespoke home extensions in Colliers Wood that bring out the best in every property. Whether you want a bright rear extension that opens onto your garden, a clever side return extension to maximise narrow alley space, or a double storey extension to add bedrooms and workspaces, we’ll help you create a home that fits your lifestyle and future plans.

Why Homeowners in Colliers Wood Choose Reltic Extend
Extending your home in Colliers Wood offers huge potential, but it also comes with challenges – conservation streets, tight garden plots, and Merton Council’s planning rules. That’s where our expertise makes the difference.
Local Knowledge
We understand the quirks of Colliers Wood homes – from narrow terraced streets to larger suburban plots. Our team knows how to respect the architectural character of each property while introducing modern design that feels natural, not forced. This local knowledge means your extension will not only look right but also work in harmony with its surroundings.
Planning Confidence
Merton Council applies strict policies on extensions, especially for terraced homes and properties near conservation areas. Navigating these rules alone can feel overwhelming. Our planning team manages drawings, applications, and supporting documents on your behalf, saving you stress and giving your project the best chance of quick approval.
Lifestyle-First Design
We don’t just measure up and build – we listen to how you live. Do you need more room for entertaining? A space that works for hybrid working? Or a family layout that flows better from indoors to outdoors? By focusing on your lifestyle, we ensure every design detail has purpose and meaning.
Cost Transparency
Budget clarity is central to how we work. With our Cost Calculator, you can see an estimate upfront before making any commitments. No hidden extras, no surprises – just straightforward, honest pricing that helps you plan with confidence.
Digital Previews Before Building
With our Design & Build 2.0 approach, you’ll be able to see your extension in digital 3D before construction begins. This ensures you know exactly how the finished project will look and feel, allowing you to make informed choices with peace of mind.
