With this in mind, it’s now easier than ever to build an orangery that suits your aesthetic and your budget. Below is a list of the main types of orangery that you can build today:

Low-End – UPVC Orangery

UPVC is the most common material used to construct conservatories but it also makes a great material for budget orangeries.

UPVC is great because it comes in a variety of different colours so you can find one that suits the look of your home.

While uPVC may look a little out of place on a period home, it makes a great addition to a more modern-looking home. UPVC is a great choice of material if you are working with a low budget.
