Home Extensions Surbiton
Extend Your Surbiton Home with Light and Comfort
Surbiton is well known for its tree-lined streets, Victorian and Edwardian homes, and its quick commute into central London. Families are drawn to the area for its schools, parks, and village-like atmosphere, but many houses still carry older layouts – small kitchens, divided reception rooms, and limited natural light.
At Reltic Extend, we specialise in bespoke home extensions in Surbiton that respect the character of local homes while adding modern flow and functionality. From bright rear extensions that open onto gardens, to clever side return designs that transform narrow kitchens, or larger double storey builds for growing families, we create spaces that make homes more enjoyable today and valuable for the future.

Why Surbiton Homeowners Choose Reltic Extend
Extending in Surbiton can be incredibly rewarding, but it also requires understanding of Kingston Council’s planning policies and the character of local housing. Here’s why homeowners trust us:
Local Knowledge
We know Surbiton’s housing inside out – from grand Victorian terraces on Maple Road to semi-detached 1930s houses near Berrylands. Our extensions always complement existing architecture while introducing modern features like skylights, bi-fold doors, and energy-efficient glazing.
Planning Expertise
Planning rules in Kingston can be strict, particularly in conservation areas. Our planning team manages the full process – drawings, statements, and applications – ensuring your project runs smoothly and stands the best chance of approval.
Lifestyle-First Design
Our projects are built around how you live. Some households want a kitchen extension that becomes the heart of the home, others choose wraparound layouts for flexible family living, while many need home office space for hybrid working. Whatever your lifestyle, we create spaces that work for you.
Clear Costs from the Start
With our Cost Calculator, you’ll see an upfront estimate before committing. No hidden extras, just transparent pricing that helps you plan with confidence.
Certainty with Digital Previews
