Thermally Efficient

Our range of house extensions preserves warmth to an extremely high standard. Whether you want to relax in your extension during the colder months or take advantage of the sun in the summer, we’ve got you covered. The structure of our house extensions includes super-insulated columns and pelmets. This works to stop any cold from making its way into your home and keeps heat from leaving. Additionally, our double-glazing windows and doors trap heat to keep your home at a comfortable temperature. This will keep your energy bills low and reduce your carbon footprint in the process!


For durability that will last years, Castle Conservatories will provide your ideal house extension. They are incredibly easy to maintain, just clean the moveable elements every so often. Our extensions use quality materials from reliable suppliers. This prevents any deterioration and decay of the materials. You can have peace of mind that our house extensions are a worthwhile investment. The versatility of our house extensions gives you more options for your project.


From our columns to our pelmets, to our range of roofs, you are protected against force. This includes strong winds and wet weather. We test all our products to reach industry standards, so you are investing in a sturdy structure. We want all our customers to feel safe in their Sutton homes. That’s why we use exceptional security in our locking system and structure. With multi-point locks, you and your possessions are protected.


Utilise your outdoor space with a conservatory for your house extension project. We offer classic, designer and performance conservatories to give you options to suit your style. Our classic conservatories provide a timeless look to your home, extremely popular in a range of home types. The heritage look can work on a modern Sutton home or fit in perfectly with a period building.

Designer conservatories invite heaps of natural light into your home, increasing the value with its modern styling. Versatile in its function, this home improvement feature will provide the wow-factor. Performance conservatories extend your space and can be used all year round due to their temperature regulation columns and windows. Find out more about our house extensions today!


Orangeries offer a different house extension option than conservatories. While conservatories maximise light with multiple windows, orangeries are more private in the layout, with more space taken up with walls than windows. The lantern orangery increases natural light with the roof design, increasing the perception of space. Using every bit of daylight, you can take advantage of your lantern orangery for a variety of purposes.

Contemporary orangeries are a popular house extension choice for its durability and elegance. With a minimalistic design, you can use your space for entertaining, lounging or as an office space to escape to. Traditional orangeries work well in period houses for added charm. We are proud of our vast range of house extensions for a worthwhile investment.
