Quick summary

Building an orangery costs between £15,000 and £20,000 for a basic design, and can rise to £50,000 or more for more elaborate features, depending on size and materials. These prices typically cover the structure and construction, with the assumption of standard-sized extensions and VAT included. It’s a worthwhile investment, often cheaper than traditional extensions and boosting resale value.

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.
