Conservatories and Orangeries

Conservatories are a great way to increase the living space of your home. Depending on your house extension type, we offer a variety of traditional and contemporary designs. Traditional conservatories are stunning and go with a wide range of buildings. Adding a house extension to your Mitcham property will add elements you didn’t know were possible.

Additionally, besides Orangeries, we offer a wide range of other products that will increase the value of your house in another way. Because Orangeries have more walls than windows, they are more private than conservatories.

Our orangeries increase natural light through roof designs and multiple windows as an alternative to conservatories, while conservatories maximize light with multiple windows.
