Quick summary

Building an orangery typically costs between £15,000 and £20,000 for a basic design, but more elaborate features can push the price up to £50,000 or more. These costs usually cover the structure and installation, and prices are based on around 10 to 20 square metres. Remember, opting for good quality materials now can save you money on repairs later.

Orangeries are having a bit of a moment, after living in the shadows of conservatories for so long. Once built in the 17th and 18th century to house - you guessed it - citrus fruit, they’re now making a comeback, as more and more homeowners look at constructing their own.

And if you're scratching your head, wondering what the difference between an orangery and a conservatory is... it’s the glazing! Orangeries are like normal extensions but they have a glazed lantern roof.

Like most extensions, orangery prices can vary. And you should definitely think of this as an extension, and not a conservatory, at least in terms of budget.

At minimum, you’ll likely spend between £15,000 - £20,000 for a basic design and build. This can go up to £50,000, or more, if you opt for more elaborate features.

This being said, organgeries tend to be slightly cheaper to their traditional extension counterparts, and offer more monetary re-sale value than a conservatory.
