Benefits of Modern Extensions

Energy Efficient

Enjoy a comfortable, cosy room with our energy efficient modern extensions. We use high-performance double glazing as standard in our modern extensions. The glazing works by trapping pockets of warm air in between the panes. This innovative technology retains heat much longer than outdated, single pane systems.

As well as the glass, the perimeter pelmet and insulating columns are energy efficient. These keep the room at a comfortable temperature, preserving heat. The materials also stop an excess of heat from occurring in warmer summer months. Save on your energy bills with our fantastic house extensions.


Our conservatories and orangeries are made to endure the most extreme conditions. The structure is fitted with a variety of weather-resistant elements, including weather seals around the frame. With an exceptional combination of high-quality materials, you won’t have to worry about decay, rot or cracking.

Regarding upkeep, modern extensions are the perfect solution for busier households. Simply clean the moveable elements including the handles and hinges, with a damp cloth every so often. This will retain a just-like-new appearance. You can relax in your room without the need for repair.


For the safety of our customers, we go the extra mile with our modern extensions. Each window and door is fitted with high-quality locking systems. The multi-point mechanisms are advanced in their functionality. Each lock is tested to reach high industry standards of security.

Keep your Epsom home, possessions and family safe with our double glazing. The glass is internally beaded, fitted on the inside of the frame to prevent exterior removal. This ensures your modern extension cannot be broken into. Have peace of mind that our installations will keep you protected.

Modern Conservatories

Upgrade your home with a modern conservatory. This modern extension style not only offers exceptional functionality but adds kerb appeal to any property. The spacious room is perfect as a relaxing space, a room to entertain or even as a study area. Add value to your Epsom property with a modern extension.

With the expansive glass lining the room and walls, modern conservatories let natural daylight stream into the room. Not only will this result in less need for your electricity, but it will give the impression of a larger space. Enjoy a sophisticated, versatile new room with a sleek appearance.

Modern Orangeries

Orangeries are a popular modern extension style. They are recognised by their brickwork, which differs from the appearance of conservatories. The walls offer substantially more privacy, yet still allow light to brighten the room. We have an array of customisation options for a bespoke finished product.

Our orangeries can be fitted with solid, tiled or lantern roofs. These elegant roofing systems each bring a unique look and a variety of practical benefits. Orangeries are secure, thermally efficient and are made to withstand strong winds and rain. This modern extension will seamlessly fit both contemporary and traditional properties.
