House Extension
Your home should adapt to your lifestyle, not the other way around. Families grow, routines shift, and space often becomes the one thing every household needs more of. Instead of moving, more and more people are choosing house extensions as a smarter way to gain extra room while increasing property value. With the right design, an extension doesn’t just add square footage — it transforms the way you live.
At Ecron, we specialise in home extensions across London and Surrey. With over 20 years of experience, we’ve helped countless families unlock the hidden potential of their homes. From practical single-storey extensions to larger double-storey extensions, every project we deliver is built on careful planning, skilled workmanship, and long-term quality.
Why Choose a House Extension?
A well-planned extension is one of the most effective ways to improve your home. The benefits go far beyond extra space:
- More functional living areas – Create open-plan kitchens, larger lounges, or flexible family spaces.
- Increase property value – A quality extension can significantly boost your resale price.
- Save money compared to moving – Avoid stamp duty, legal fees, and the stress of relocating.
- Tailored to your lifestyle – Extensions designed to match how you live and what you need.
- Future-proofing – Build adaptable layouts that serve you now and grow with your family.
By extending your home rather than moving, you keep the location you love while creating a space that finally works for you.
Types of House Extensions
Every property has its own potential, which is why we design solutions that are tailored to each client.
Single-Storey Extensions
Single-storey extensions are one of the most popular ways to add practical, stylish living space. They’re ideal for expanding kitchens into open-plan layouts, adding dining areas, or simply creating a brighter, more welcoming ground floor. With features like skylights, large windows, and sliding or bi-fold doors, these extensions maximise natural light and connect indoor spaces with gardens.
Double-Storey Extensions
For homeowners who want the most impact, double-storey extensions provide a major upgrade. By extending both floors at once, you gain valuable new bedrooms upstairs while enlarging kitchens, dining rooms, or lounges downstairs. This type of project is cost-efficient on a per-square-metre basis, adds significant long-term value, and is often the best choice for growing families.
Rear, Side, and Wrap-Around Extensions
In addition to single-storey and double-storey extensions, we also build rear extensions, side returns, and wrap-around designs. These options make clever use of existing land to expand your home without compromising flow or style. Whether you want a bigger kitchen-diner, a utility room, or extra living space, we’ll design an extension that works perfectly for your property.
