Tiled Roof Extensions

For the most seamless transition from your existing home to your modern extension, choose our tiled roof extensions. As the roofing is made from tiles, you can match them to your current tiles to make it feel like it has always been part of your home. Tiles make for excellent thermal efficiency to create a space you can enjoy all year round. Due to controlled temperatures, you won’t have to worry about cold winters and boiling summers as our modern extensions keep the warmth inside and the cold out in the winter months, keep the heat out, and keep your space ventilated in the summer months. Along with the added privacy it gives, your modern extension will feel like a regular room. You can also add glazed panels if desired, that can be strategically placed to add extra light to your space.

Solid Roof Extensions

Like our modern tiled roof extensions, our solid roofs are extremely popular with our modern extensions. Instead of tiles, they come with modern panels that add a contemporary touch to your home that doesn’t compromise performance. These panels are highly energy efficient and weatherproof, so no matter the weather, you can enjoy your space without the worry of dampness, mould or warping. Our modern extensions are a great way to add value to your home and increase its curb appeal due to the added square footage as well as the stylish design.

Modern Extensions with Roof Lanterns

For a stunning addition to your home, our roof lanterns are a stylish and sleek choice that allows sunlight to flood your home, creating a brighter and more luminous space. Their slim profiles include fewer bars and more glazing to enable high levels of sunlight so you can make the most of your sunny views. You won’t have to worry about cold temperatures or leaks as our roof lanterns are highly energy efficient and include double glazing that keeps the heat you generate in your home inside. Our expert installers will fit your modern extension professionally and to the highest standards so you won’t experience any gaps for the cold breeze to enter. 

For a smooth transition from the inside to the outside of your Cheltenham home, why not opt for our bifold doors, french doors or sliding patio doors to open up your space and make the most of your garden?
