Home Extensions Wimbledon
Redesigning Wimbledon Homes for Modern Living
Wimbledon is famous worldwide for its tennis, but locals know it best for its leafy streets, excellent schools, and a mix of Victorian terraces, Edwardian semis, and spacious detached houses. While the area is one of South West London’s most desirable, many properties still have older layouts — smaller kitchens, separate dining rooms, and limited connections to gardens.
At Reltic Extend, we create bespoke home extensions in Wimbledon that balance heritage with modern design. Whether you’re planning a bright rear extension to bring in natural light, a side return project to transform a narrow kitchen, or a double storey extension for extra bedrooms and bathrooms, we’ll design a space that works for you and your family.

Ready to Plan Your Wimbledon Extension?
From the first consultation to final completion, we make extending your home simple, clear, and stress-free. Our team manages design, planning, and construction so you can enjoy the process and the results.
Why Wimbledon Homeowners Choose Reltic Extend
Wimbledon’s charm lies in its mix of history and greenery, but that also brings planning complexities – conservation areas, larger plots, and Merton Council’s strict guidelines. Here’s how we help:
Local Expertise
From period homes around Wimbledon Village to 1930s semis in South Wimbledon, we know the area’s housing styles inside out. Our extensions enhance original features while bringing in modern touches such as skylights, glass walls, and energy-efficient insulation.
Planning Confidence
Navigating Merton Council’s planning rules can be daunting. Our planning specialists prepare drawings, applications, and design statements, ensuring your project progresses smoothly.
Lifestyle-Led Design
Your home should match the way you live today. Families often want a kitchen extension as a central hub, while professionals may prefer flexible layouts with space for remote working. We design around your lifestyle, not just square footage.
Clear Costs from the Start
With our Cost Calculator, you’ll receive an upfront estimate before work begins. No hidden extras — just complete cost clarity.
Visual Certainty with Digital Previews
Through our Design & Build 2.0 process, you can explore your new extension digitally in 3D before construction starts. This gives you peace of mind that the final result will meet your expectations.
