By the BSD Design & Build Team
At BSD Design & Build, we believe your home should grow with you — not hold you back. Over the years, we’ve helped countless families and property owners across North and North West London create more space, more comfort, and more value through beautifully designed home extensions.
We know what it’s like to feel your home getting a little too snug — maybe you’ve got a growing family, you’re working from home more, or you just wish you had that open-plan kitchen-dining space for entertaining. Whatever the reason, a well-planned extension can completely transform how you live — and it often costs far less than moving to a new property.
✨ Why Choose a Home Extension Instead of Moving?
Extending your home is one of the smartest ways to upgrade your lifestyle without the stress and cost of moving. There’s no packing boxes, no stamp duty, no estate agents — just a tailored space that suits your needs perfectly.
A home extension allows you to:
Add more living space and comfort for your family.
Increase your property’s value significantly.
Create modern layouts like open-plan kitchens or garden-facing lounges.
Preserve the charm of your existing home while improving its functionality.
We’ve worked on everything from Victorian terrace side returns in North London to double-storey rear extensions in the suburbs — each one designed with care and crafted to last.

🏠 What Types of Extensions Can You Build?
We specialise in all major types of home extensions, including:
Rear Extensions – Perfect for extending your kitchen or adding a family room.
Side Return Extensions – Great for terraced homes, adding width and light.
Wrap-Around Extensions – Combine side and rear extensions for maximum space.
Double-Storey Extensions – Add bedrooms or bathrooms while expanding your ground floor.
Garage Conversions – Turn unused garages into offices, studios, or guest rooms.
Every home is different, and so is every build — that’s why we tailor each project to your property, budget, and lifestyle.
🌿 A Smart Investment That Adds Real Value
An extension isn’t just about gaining extra space — it’s about adding long-term value.
Many of our clients see their property value rise significantly after a build, particularly in popular parts of London where space is at a premium.
By combining thoughtful design with solid craftsmanship, we make sure your new extension looks like it’s always been part of your home — not an afterthought.
