Conservatories or Orangeries – Which One Is Right For Me?

When looking at conservatories for your property, it’s important to know what the differences are for you to get the best one for your home.

Conservatories offer a sleek and cost efficient extension to your property. Their uPVC structure creates a light and airy structure that can be used as anything from a dining room, utility room or even a greenhouse depending on your taste and needs.

Used in the 19th century on wealthy estates to house citrus trees during the winter months, Orangeries provide a high-class look to any property. Recommended for larger buildings or properties with large gardens, their brick built structure offers superior insulation and privacy than uPVC conservatories.

Frequently Asked Conservatory Questions

IThe majority of conservatories with a tiled conservatory roof will not require planning permission. This is because they are covered under what is known as a 'permitted development.'

However, Building Regulations will apply if you want to build an extension on your home.

The main difference between a conservatory and an orangery is how the roof is constructed. A conservatory roof is over 75% glazed whereas an orangery roof has less than this amount. A conservatory also has over half of its wall space glazed whereas an orangery can include more brickwork than this.
A glass conservatory can cost as little as £4,000 depending on the style you choose and the amount of building work you need. Larger glass conservatories with more building work can cost £20,000 and above. If you know the conservatory style and size you need or just want an idea of cost our online conservatory cost calculator will give you a guide price.
A Loggia Conservatory can cost about £15,000 to £20,000 for an average size. The Loggia Conservatory is a popular style but can be more expensive than traditional conservatory styles.
A Loggia Conservatory can cost between 20% to 50% more than a uPVC conservatory. It is a good idea to shop around for quotes in order to get a competitive conservatory cost.
The average conservatory cost begins in the region of £4,000 to £5,000. This will be for a reasonably small and basic conservatory. The cost of a conservatory can be as much as £40,000 to £50,000. This will be a large conservatory, fully fitted with all building work included. As this is a wide spread it is a good idea to know your style and size in order to get an average conservatory cost.
Orangeries have more solid wall and roofing than a conservatory. This means they are able to retain more heat in the Winter and stay cooler in the Summer.
However, modern conservatory extensions such as a tiled roof conservatory or solid roof conservatory, can offer just as much warmth.
This will largely depend on your location. You will find that certain areas have different setbacks based on the use of the building. We recommend that you check with your local council or take a look at the Goverment's Planning Portal.

You must notify your neighbour if you want to:

- Build on or at the boundary of your 2 properties - Work on an existing party wall or party structure - Dig below and near to the foundation level of their property
It is possible to convert a conservatory to an orangery but it isn't a simple process. A surveyor will need to come out and assess your property and conservatory to see if it is at first , feasible.
Both extensions and orangeries often require planning permission and in order to satisfy requirements, a new structure will have to be built.
On average, an orangery can cost anything from £10,000 to £20,000. It is likely to cost double the amount of a conservatory, however it's important to note that an orangery provides more functionality and home value when compared to standard glazed conservatory.
An orangery allows you to benefit from both conservatory and extension, being a combination of the two.
It is possible to build either a conservatory or a single-storey extension without gaining planning permission if: firstly, it has a maximum height of 4 metres or 3 metres high if situated within 2 metres of an existing boundary. The conservatory itself does not exceed over half the size of the garden.
