Glass extensions for homes in Kent and the South East

When you want to extend your home, but a conservatory isn’t suited to your requirements, a home extension is a perfect solution. An extension could be used to create a larger kitchen, an additional living area, or a dining room. The extra space will transform your family life. With our high-quality insulating materials, it will stay an optimal temperature all year round, performing as your current home does.

Why choose a home extension?

If you need the additional floor space and you’re considering moving to a larger property, an extension could be a great solution. Moving to a new house is expensive and disruptive. If you’re happy where you are but you just need a bit more space, a home extension will create a versatile living area. If you do decide to sell up in the future, an extension can add upwards of 10% to the value of your property. Get inspiration for extension ideas, designs and styles here.

    A range of durable roof extension options in Kent

    Tiled roofs are available in a range of colours, including brick red and slate grey, so we can be sure to offer the perfect finish that exactly matches your existing home. Tiled roofs are popular thanks to their lightweight and fully insulated design, meaning they effectively retain the warmth during the colder seasons and are draught-free. Their innovative installations also maximise their robustness so they can effortlessly withstand harsh weathers without weakening over time.

    Glass roofs are the ideal roofing system if you wish to brighten your extension and let the natural light provide an airy and fresh atmosphere. You can choose from clear glass or tinted glass to achieve your dream aesthetics. With our advanced glazing options they create the optimal interior temperature in both the winter and summer; and its solar cleaning property repels the sun's rays in the warmer months, so it won’t overheat like older glazed roofs used to. It also features self-cleaning abilities, eliminating any upkeep!

    Your conservatory journey with us

    A new room that stays an optimal temperature all year round

    Our home extensions will perform like your existing home does, staying cooler in the summer and warmer in the winter. So, your new space can be used all year round. Thanks to its advanced thermal capabilities, you’ll even save money on your heating bills and reduce your homes carbon footprint! The walls are fully insulated with a multi-layered design, and innovative under cladding is incorporated, so when it needs warming up, it will absorb the sun's rays. In the same way, when it needs cooling down, the glazed panels will let the heat seep out.

    Our double-glazed windows and doors can achieve A+ energy ratings, the best available on the market. Their high-performance design includes two layers of argon gas filled glazing, fitted with advanced spacer bars and tightly fitted frames to further enhance your extension's energy efficiency.
