1. 🏠 Add Valuable Space Without Moving

Space is at a premium in London, and for growing families or those working from home, things can quickly feel cramped. A well-planned extension gives you:

  • A larger kitchen or open-plan living area
  • Extra bedrooms or a guest suite
  • A home office, gym, or hobby room
  • Improved flow and functionality throughout your home

Rather than facing the stress and expense of relocating, you can create the space you need—right where you are.


2. 💷 Boost Your Property Value

Home extensions are known to significantly increase the value of London properties. With house prices in the capital at a premium, even a modest extension can add tens of thousands of pounds to your home’s market value.

Buyers are actively looking for homes with:

  • Larger kitchens and family spaces
  • Additional bedrooms
  • Ensuite bathrooms or utility rooms

With a quality build from FOX HOME BUILDERS & DOUBLE GLAZING, your extension will look seamless and add long-term financial benefit.

We specialise in quality home construction across London, including expert house extensions, stylish loft conversions, and complete new build projects. Whether you’re expanding upward or outward, FOX HOME BUILDERS delivers tailored solutions throughout North, East, South, and West London with precision and care.


3. 🌆 Designed for London Living

Building an extension in London isn’t just about bricks and mortar—it’s about smart, space-saving design that complements the city’s unique architecture and planning rules.

We consider:

  • Local council planning permission and building regulations
  • Matching materials to existing London brickwork
  • Maximising natural light in narrow plots
  • Creative use of side returns or rear extensions
  • Energy-efficient windows and glazing

Our team specialises in building extensions that feel like a natural part of your home, not an add-on.


4. 🔒 Energy Efficiency & Modern Comfort

A home extension gives you the opportunity to upgrade your living standards. When you work with FOX HOME BUILDERS, we include:

  • Modern insulation
  • High-performance double or triple glazing
  • Energy-efficient lighting and heating
  • Contemporary finishes

This can lower your energy bills and make your home more comfortable year-round—especially important in London’s unpredictable climate.


5. 🛠 Tailored to You – 100% Customisable

Unlike buying a new house, a home extension gives you complete control. Choose your layout, materials, glazing options, flooring, and more.

Whether you’re dreaming of a sunlit dining room, a luxurious master suite, or a new workspace—we bring your vision to life with expert planning and precision craftsmanship.
