Benefits of Modern Extensions

Energy Efficient

It has never been more important to ensure that your Kingston home is as thermally efficient as possible. With this in mind, our modern extensions are designed to reduce your energy bills through their heat retaining properties. These include the use of high quality materials such as our thick frames and insulated columns. 

Our insulated double glazing will keep you comfortable all year round! Stay cool in the summer and warm in the winter with our efficiently designed conservatories and orangeries. The windows and doors we use in our products are designed to trap pockets of air, so your new investment will adapt to the season. A more thermally efficient home will also help reduce Kingston’s carbon footprint too!


Enjoy peace of mind with a durable home extension. All of our products are built to last, designed to be strong and secure for years to come. You will no longer have to worry about any decay and deterioration with our high quality designs.

As well as being durable, our conservatories and orangeries require little to no maintenance all year round. All that is required is a quick wipe with a damp cloth to remain shiny and new!


At Castle Conservatories, we understand that safety is of the utmost importance to our customers. That’s why all of our products are fitted with secure locking systems, tested to ensure they meet the highest standards of security. Our home extensions are also built with durable double glazed windows to prevent intruders.

Enjoy a durable and weatherproof addition to your home. Damp and mould will no longer be an issue with our conservatories and orangeries. Your shiny and brand new surroundings will be the ideal place to relax!
