Thermally Efficient

Our range of house extensions are designed to preserve your homes 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. These work to stop the cold from making its way into your home while keeping warm air in. Additionally, our double-glazing windows and doors also trap heat, keeping your home at a comfortable temperature. Over time this could even help reduce  your energy bills low and carbon footprint by lessening your reliance on central heating!


Choose Castle Conservatories for durable builds that will last years. Our extensions are incredibly easy to maintain, just wipe down the moveable elements every so often. Through the use of quality materials from reliable suppliers, our extensions wont deteriorate or decay, so you can enjoy peace of mind that our house extensions are a worthwhile investment.


From our columns to our pelmets, to our range of roofs, you and your home are protected against unpredicted force, this includes strong winds and wet weather. We test all our products against rigorous industry standards, so you can rest assured that 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 systems and structures, with our multi-point locks you and your possessions are protected.


Utilise your outdoor space by choosing a Castle conservatory for your house extension project. We offer classic, designer and performance conservatories to give you an array of options to choose from, so you can match your homes style. Our classic conservatories provide a timeless look to your home and are an extremely popular style amongst Sutton homeowners as they can fit with both modern and traditional builds.

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


Our range of Orangeries offer a different style of extension to our conservatories. While conservatories maximise light with multiple windows, orangeries are more private in their layout, with more space taken up with walls than windows. The lantern orangery increases natural light through its roof design, increasing the feel of your 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 their 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 particularly well in period homes, for that added bit of charm.
