Thermally Efficient

Warmth is maintained to a very high standard in all of our home extensions. We have everything you need to make your extension a comfortable place to relax during the winter or enjoy the summer. Columns and pelmets in our house extensions are super-insulated. Your home will remain warm throughout the year when this is in place. Moreover, double glazing traps heat within the home to keep it comfortable. By doing this, you will reduce your carbon footprint and keep your energy bills low.


Castle Conservatories will provide you with a long-lasting house extension that will last for many years. It’s very simple to clean the small parts of the house extensions that need maintaining. Simply wipe down the components once in a while to keep them clean. All of the materials are supplied by trusty and professional suppliers. As a result, they won’t deteriorate or decay. With our house extensions, you can be sure that your money is well spent.

Our products are tested to meet industry standards, so you can rest assured that your investment is solid. Castle conservatories aim to provide peace of mind to all our customers.

Conservatories and Orangeries

Consider adding a conservatory to your house extension project to make the most of the outdoors. We provide a classic, designer, and performance conservatories, so you can choose the style that suits you. In addition to providing a timeless look to your home, our classic conservatories are extremely popular with a variety of home types. Heritage looks are ideal for modern Sutton homes as well as period buildings.

Designer conservatories bring as much natural light into your home as possible, enhancing its value with their modern styling. This home improvement feature is versatile in its function and provides the wow-factor. Performance conservatories extend your living space, and their temperature-regulating columns and windows allow them to be used all year round. Find out more about our house extensions today!

House extensions such as orangeries are different from conservatories. Orangeries are more private, with more space being taken up by walls than windows, but conservatories maximise light with multiple windows. Lantern orangeries increase natural light through their roof design, increasing the perception of space. You can use your lantern orangery for a variety of purposes by maximising daylight.

The durability and elegance of contemporary orangeries make them a popular choice for house extensions. If your space is minimalistic, you can use it as a space to entertain, relax, or work. A traditional orangery makes a charming addition to a period home. We are proud of our vast range of house extensions for a worthwhile investment.
