Thermally Efficient

You will feel cool and comfortable in the summer, and in the winter, you will feel warm and cosy. Our house extensions are constructed from the highest quality materials to ensure optimum energy efficiency.

We ensure this warmth’s preservation throughout the full house extension by installing very well-insulated columns and pelmets.

With our double glazed windows and doors, you can keep your home comfortably warm. A low energy bill and a reduced carbon footprint are two great ways to reduce your carbon footprint, and we at Castle Conservatories can provide that for you.  


Castle Conservatories will provide you with a long-lasting house extension that will last for many years. Simply wipe down the different components once in a while to keep them clean. Materials from reliable sources are used in these house extensions, and consequently, the materials do not deteriorate or decay. Our house extensions are an excellent investment, and you can feel secure in your new extension when you get one from us.


The house extensions we provide and the pelmets and roofs we offer provide you with a high level of protection, even in adverse weather conditions. You will be investing in a sturdy structure when you purchase a house extension because our products meet industry standards. Our mission is to ensure safety in every Kingston home. As a result, our locks and structure offer exceptional security. Multiple locks will protect your belongings.

Conservatories and Orangeries

Adding a conservatory to your home increases its value significantly. We offer traditional and contemporary house extensions depending on your extension type. The traditional conservatory is amazingly beautiful and can blend in with almost any type of building.

Furthermore, we offer a wide variety of other products that will enhance the value of your house in different ways. Orangeries are more private than conservatories since they require more walls than windows. While conservatories maximise light with multiple windows, orangeries increase natural light through roof designs and lanterns.
