Orangery cost guide: Extend your home with this classic home improvement project

If you’re looking to add space to your home, you may be thinking about building an orangery instead of a standard extension or conservatory. If that’s you, then you’re in luck. Check out this orangery cost guide to give you an overview of the average prices in the UK.

An orangery is basically a hybrid of an extension and a conservatory, and can add a stylish space to your home. They offer a lot of light thanks to the glass walls and ceiling, and have the benefit of being usable all year round.

Though be warned, an orangery is an investment. It can be a similar price to a home extension. But for many, it’s worth the cost to add a wow factor to your home and increase the value of your property.

Best of all, there are so many orangery ideas you could do!

ItemRange - LowRange - High Average cost
Average orangery cost (per m2)£2,000£2,500£2,250
Average cost of an orangery (16m2)£30,000£35,000£32,500
Small orangery (4m x 4m) - supply only£5,000£18,000£11,500
Medium orangery (6m x 6m) - supply only£12,000£30,000£21,000

How much does an orangery cost?

On average, the typical cost of an orangery in the UK is around £32,500 – that’s for a 4m x 4m orangery. If you’re wondering per square metre, a guide cost is about £2,250 per m2.

Those costs are for the complete project, including the build and supply of the orangery structure, internal electrics, plastering, lighting and all associated labour costs.

Cost of orangery structure

The average costs for supplying a hardwood structure for your orangery (excluding labour, fittings, design, features and fittings, windows, doors, etc) are:

Supply of small orangery cost (4m x 4m): £5,000 to £18,000

Supply of medium orangery cost (6m x 6m): £12,000 to £30,000

Supply of large orangery cost (7m x 7m): £18,000 to £100,000

The cost of an orangery may be higher than a standard conservatory, but it generally tends to offer more functionality and have a bigger impact on the property value. Orangeries are also more energy efficient on the whole, thanks to their more sturdy structure.

cost of orangeryFactors affecting the cost of an orangery

Due to the often bespoke nature of orangeries, there are a number of factors that can impact the overall price you’ll pay. These include:

  • Size and shape of orangery
  • Traditional or bespoke design
  • Type of roof
  • Type of wall
  • Insulation (wall, floors and roof)
  • Heating, electrics and plumbing
  • Quality and type of fixtures and fittings
  • Any excavation or other prep work needed

Types of orangery

The world of orangeries can be very varied, with many having bespoke designs. That said, there are generally three common types of orangery that British homeowners go for. Your choice of structure will directly affect the cost of your orangery:

uPVC orangery – Very easy to maintain, resistant to UV light and usually come with a 10-year guarantee. uPVC orangeries are one of the most popular options in the UK.

Timber frame orangery – Often a choice of softwood or hardwood for the glass frame, the latter being more expensive but has a longer lifespan. Softwood is usually painted, while hardwood tends to be varnished. Wood frames are one of the best insulation materials for windows.

Aluminium orangery – Although aluminium structures are available, composite framing tends to be more popular, combining wood and aluminium – with a lifespan of up to 85 years. The aluminium protects the outside from the elements, and the inner timber layer provides effective insulation.

There are so many more orangery ideas that you can look at to get more inspo!

Do you need planning permission for an orangery?

You don’t usually need planning permission for an Orangery as it’s classed as permitted development. We recommend speaking with your local planning office before starting your orangery project.

Useful orangery checklist

  • Speak to your local planning office before starting any work to confirm any planning or building regulation requirements.
  • Contact local orangery specialists for professional advice and accurate quotes.
  • Shop around for fair and competitive orangery costs.
  • Always hire tradespeople with relevant experience and ask for references of their previous work.
