What’s The Average Cost Of An Orangery?

Orangeries are one of the finest additions you can add to your home. When installed and designed by a professional, not only will they add more space to your property but they will add kerb appeal to your property and it’s unlikely you will need planning permission for it. 

The cost of your orangery cost will depend on a variety of factors, not just the materials and installation. As a company that specialises in identifying the best craftsman and tradesmen across the UK, we’ve been able to compare all associated costs when it comes to building an orangery. 

Is the Price of an Orangery Worth It?

As briefly mentioned before, orangeries can add a lot of value to your property as well as transform that section of your home into a stunningly warm and vibrant hang-out area for all seasons. Yes, orangeries are more expensive than a traditional lean-to, but they also offer far more protection, value to the home and are incredibly versatile. 

How Much are Orangeries? 

Orangeries are not the cheapest addition to your home. On average, you can expect to pay anywhere between £20,000 to upwards of £30,000. However, there are ways that you can spend as little as £10,000 on an orangery, but this obviously limits the size and space. Orangeries, whatever their size and scale are almost always more expensive than conservatories. The main reason for this is because orangeries typically offer more functionality and value to your home than your typical lean-to or conservatory. 

If you’re attempting to price up your orangery based on per metre squared, then an average estimate would be between £1,800 and 2,500. To give an example of how much a 16m2 orangery would cost, you’d be looking at around £30,000 – £35,000. 

What are Orangeries Typically Made from?

In most cases, orangeries are built from brick and mortar, with the roof being more substantial than a typical conservatory roof (they are usually deeper and extravagant). Orangeries are also designed to be more thermally efficient, making them ideal to relax in through all the seasons. 

Orangery Costs for Budget Projects 

Although orangeries are typically more expensive than other garden extensions (conservatories, lean-tos etc), their prices can vary depending on your requirements. In the short-term, you may consider going for a mid budget orangery, which isn’t actually a bad idea if you plan to extend it further in the future. Small timber-based orangeries can cost as little as £7,500.

However, if you’re looking to install a larger orangery, the cost will obviously be more expensive. 

For budget orangeries, you can expect your contractors to use cheaper materials during the build. Timber frames, for example, offer excellent durability, however, this may impact the structural integrity of the building. So, while this is an aesthetically pleasing and cost-effective solution, it’s important to talk through your options with your contractors to ensure you’re getting the bang for your budget. We’d personally recommend building with wood, for both aesthetic purposes as well as structural. 

If you are working on a budget but have plans to renovate your orangery living space over time, be sure to invest in the right areas. Double glazed windows, doors and decoration should be prioritised above all else; as they’re typically the most expensive and require experienced tradesmen to fit (this is something we can help with). Additionally, if you’re looking to sell your house in the future, this is the sort of thing you want to invest money into, as it can raise the price of the house considerably. 

Orangery Costs for Bigger Projects 

Some orangeries, those on the highest end of the scale can cost upwards of £100,000. However, that really is the top scale orangery cost. Most bigger orangeries cost between £20,000 and £50,000 and these prices vary depending on many factors; namely the size of the extension, thermal insulation, window and door requirements etc. 

Even a 4m x 4m can cost as much as £20,000 with basic finishes. 

Be aware that foundations and building costs actually add up to about half of the full cost. You may be able to save some money on finishing touches (painting, decorating etc). You will be able to get away with saving money on the finishing touches, but try not to apply this same logic for the overall structure of the orangery. 

Something that really differentiates a conservatory from an orangery is the roof. Conservatory roofs are always considerably cheaper, as they can be made from lower-grade materials. Whereas orangeries utilise a roof lantern structure, which requires better materials and more experienced trades people. 

You can expect to pay considerably more for an orangery roof than a conservatory roof. One of the main reasons is the installation of roof vents in orangeries; which is needed on hot days to ensure the room does not become uncomfortable. 

Points to Take Away When Buying an Orangery

It’s vital that you plan a budget before you purchase your orangery. Speak with an experienced contractor, or even a few contractors to get an idea of how much installation and materials will cost before committing. 

The average cost of a 20m2 orangery in the UK is about £20,000, which in comparison with a single extension, which would cost around £30,00 – £55,000, is an absolute bargain. 

Try and plan for a big-budget when installing an orangery, because not only will this give you an exceptional finish and great room to enjoy throughout the seasons, but it can add up to £20,000 or upwards of £30,000 value to your property.

What is an orangery?

Although likened and often confused with conservatories, orangeries are predominantly made from brick and feature large windows and a flat roof with a glass lantern. In contrast, a conservatory is a predominantly glass structure that features a brick or stone base with a pitched, glazed roof.

Can you use an orangery all year round?

Yes, a professionally designed and installed orangery should be able to be enjoyed all year round. Architects will work thermal insulation into the design so that you’re able to use the orangeries throughout the colder months without a problem. Additionally, the reduced amount of sunlight will help keep the orangery cool in the warmer months. 

One of the benefits of an orangery is that it can be used all year round! An orangery styled as a traditional extension, with brick walls and a solid perimeter, will trap more heat to keep it warm in the winter. The reduced amount of sunlight will also keep it cooler in the summer.

Do I need planning permission for an orangery?

Like conservatories, orangeries are usually considered permitted developments and will not need planning permission in most cases. There are some exceptions to this, however, when the specifications of the planned work don’t meet the criteria set. If you think your dream orangery will fall outside of the guidelines, it is best to check.
