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.




However, it tends to be bulkier than other materials and may draw focus away from the surrounding area.

It is also the least durable option for orangery materials. A uPVC orangery will cost around £10,000-£20,000 to build depending on the size.

Mid-Range – Aluminium Orangery

Aluminium frames are very strong and durable. They are ideal for building structures of all sizes and offer slim sightlines in comparison to uPVC and timber.




You can choose many colours of aluminium frame to suit your needs and they can also be finished with a timber grain effect, making them an excellent alternative to a real wood frame.

Aluminium frames are higher in cost than uPVC frames. The average cost for an aluminium orangery is around £20,000-£40,000 depending on the size.

High-End – Timber (Hardwood Orangery or Softwood Orangery)

Timber frames are the most expensive option for orangery materials. They are beautiful and offer a traditional aesthetic that works on a wide range of homes but they are especially suited to period homes.




Depending on the size of your build, this option can end up being quite costly. Timber frames will need regular maintenance in the form of treatments to ensure it doesn’t rot, so this is something that needs to be considered before you commit to it.

A timber orangery will cost around £35,000-£60,000 depending on the size.
