What does it cost to build an orangery?
What the cost of building an orangery will be is going to depend upon what type of orangery you are thinking of building.
Because they are solid, unless you use a high proportion of windows, they are likely to need planning permission to be built, which will add a few hundred pounds to the cost.
You could expect to pay in the region of at least 10,000 to 15,000 for a basic orangery, and some of the more ornate, elaborate and larger orangery designs can easily be in the region of 30,000 to 50,000 or more. A good guide to all things orangery can be found here – http://www.orangerycost.co.uk/
