A house extension with an orangery could be the ideal choice to increase your living space or create a chic and functional home office.

This article will examine the essential characteristics of orangery extensions, including their structure, features, and advantages. We’ll delve deeper into the history of orangery additions and how they changed over time to become the fashionable and helpful living spaces they are today. 

For more information on orangery extensions, read if you’re considering adding one to your house or want to know more about this standard home improvement option.

What Is An Orangery Extension?

An elegant orangery extension with spacious interiors and abundant natural light, seamlessly connecting indoors with outdoors.

In the 17th century, an orangery was first built to grow exotic plants, especially citrus fruits, in colder climates. It is a glazed addition. Most orangeries were large, opulent structures made of brick, stone, or wood, with big windows and a glass roof that let in a lot of natural light.

Advantages Of Having An Orangery Extension

A modern orangery extension offers more living space, one of its main benefits. However, they can also be used as home offices, kid’s playrooms, or spaces for crafts and hobbies. Orangeries are frequently used as dining rooms or living rooms. Due to their size, brightness, and abundance of natural light, they are comfortable places to be.

Improving a home’s curb appeal is another benefit of a modern orangery addition. Orangeries can elevate a property by bringing a touch of elegance and sophistication. They are frequently designed to blend in with the home’s existing architecture.

A property’s value may also rise due to an orangery addition. When it comes time to sell a home, adding an orangery is a relatively inexpensive way to expand the living area. It can also be a selling point for potential buyers.

Factors to consider before designing an orangery extension:

Factors to consider before designing an orangery extension:

Before embarking on the design of a modern orangery extension, there are several factors that homeowners should consider:

The purpose of the extension

Considering the intended use is the first step in designing an orangery addition. Will it be a dining area, a lounge, a home office, or a playroom? The extension’s purpose will influence the orangery’s size, layout, and style.

The style and architecture of the house

Another important consideration is the style and architecture of the existing house. An orangery extension should complement the existing architecture, and its design should be consistent with the house’s overall style.

The location and orientation of the extension

The extension’s design will also be influenced by where it is located and how it is facing. An orangery extension facing south or west will get more sunlight, which should be considered in the design. 

To ensure seamless integration with the existing outdoor space, the location of the extension within the property must be carefully considered.

The size and layout of the extension

The size and layout of the extension will depend on the purpose for which it will be used, as well as the available space. The design should maximise the available space while ensuring the extension does not overpower the existing house.

Choosing The Suitable Materials For An Orangery Extension

Choosing suitable materials is an important consideration when designing an orangery extension. The materials should be aesthetically pleasing and functional, providing good insulation, weather resistance, and durability. Here are some materials to consider:

Glass and glazing options

When creating an orangery extension, the glass and glazing options must be carefully considered. Glass with two or three layers of glazing will insulate well, and self-cleaning glass will require less maintenance. Tinted glass or blinds can be used to lessen glare and regulate the amount of sunlight entering the orangery.

Frames and structure

The frames and structure of the orangery should be strong and durable, providing good support for the glass. Common materials used for frames include aluminium, uPVC, and timber.

Roofing options

The roof of the orangery can be glazed or tiled, depending on the design and the homeowner’s preference. Glazed roofs provide more natural light, while tiled roofs can be designed to match the house’s existing roof.

Designing the interior of an orangery extension:

Designing the interior of an orangery extension

The interior design of an orangery extension is just as important as the exterior design. Here are some factors to consider:

Choosing furniture and decor

The orangery’s furnishings and decorations should be appropriate for the space’s intended use. For instance, if the orangery is intended to serve as a dining room, a dining table and chairs should be included in the furniture. The decor should be consistent with the overall style of the orangery and the existing house.

Lighting options

Lighting is an essential consideration in the design of an orangery extension. The orangery should have good natural light, but additional lighting may be required for use in the evening. LED lighting is a popular choice, as it is energy-efficient and can be controlled remotely.

Heating and ventilation considerations

It should be heated and appropriately ventilated to make the orangery comfortable to use all year long. Because it offers a cosy and effective way to heat the room, underfloor heating is a popular option. The orangery can be ventilated through windows or vents in the roof, keeping it from getting too hot during the summer.

Building an Orangery Extension

Planning permission and building regulations

It’s essential to determine whether you need planning permission for a conservatory or not before beginning to construct an orangery extension. 

Orangery additions may or may not require planning approval, depending on the addition’s size, location, and height. The extension must receive approval of building regulations to meet all safety and environmental requirements.

Site preparation

The site must be ready before an orangery extension can be built. This entails clearing the area of any vegetation or obstacles and setting up the foundation. The foundation needs to be strong and stable to support the weight of the orangery and may need to be dug deeper than for a typical extension to account for the extra weight of the glass.

Building the structure

Setting up the frames is the first step in constructing the orangery extension’s structure. Aluminium, uPVC, and wood are just a few materials that can be used to make frames. The existing property’s budget, design, and architectural style are just a few of the variables that will affect the material choice.

The glazing can be installed after the frames are constructed. Double or triple glazing is advised for efficient energy use and good insulation. The glazing can be self-cleaning, tinted, or coated with a solar control layer to offer additional advantages like lessened cleaning requirements, diminished glare, and heat control.

According to the homeowner’s design and preferences, the orangery extension’s roof may be tiled or glazed. While tiled roofs can be made to match the house’s existing roof, glazed roofs offer more natural light. In addition to offering effective insulation, a well-designed roof will also stop rainwater from penetrating through.

Interior finishing

The orangery’s interior can be finished once the building is complete and used as a living area. This involves installing heating and ventilation systems, electricity, and lighting.

The size of the orangery, the existing heating system, and the homeowner’s preferences are just a few variables influencing the choice of heating and ventilation systems. Due to its ability to efficiently and comfortably heat a room, underfloor heating is a popular option. The orangery can be ventilated through windows or vents in the roof, keeping it from getting too hot during the summer.

To meet safety requirements, a licensed electrician should install electricity and lighting. Orangery extensions frequently use LED lighting because it is cost-effective and remote-controllable.

The orangery can be transformed into a usable living area by adding furniture and accessories. The furnishings and decorations should complement the room’s function, the orangery, and the house’s overall design.

Maintenance and upkeep

The orangery extension’s maintenance and upkeep should also be considered. The glazing must be cleaned frequently to maintain its aesthetic appeal and functional integrity. To avoid water damage, fixing any leaks or cracks in the roof, glazing, or glazing fast is essential.

The frames and other structural components should also be regularly inspected for signs of wear and tear, and any necessary repairs should be carried out promptly. In addition, the heating and ventilation systems should be regularly serviced to ensure they work correctly and efficiently.

Benefits of an Orangery Extension

An orangery extension can bring a range of benefits to a home, both practical and aesthetic. Here are some of the key benefits:

Increased living space

An orangery extension can provide valuable additional living space to a home. Whether it is used as a dining area, a sitting room, or a playroom, an orangery can provide a versatile and flexible space that can be used in a variety of ways.

Natural light

One of the main benefits of an orangery extension is the natural light it brings into the home. With large panels and a glazed roof, an orangery can flood a home with natural light, creating a bright and airy atmosphere.

Enhanced views

An orangery extension can also provide enhanced views of the surrounding landscape. Whether it is a garden, a courtyard, or a stunning view of the countryside, an orangery can provide a beautiful and immersive view that can be enjoyed year-round.

Improved energy efficiency

An orangery extension can also improve the energy efficiency of a home. With modern glazing and insulation, an orangery can help to reduce heat loss and save on energy bills.

Increased property value

An orangery extension can also increase the value of a property. With its aesthetic appeal and practical benefits, an orangery can be an attractive selling point for potential buyers.

Design flexibility

An orangery extension can be designed to suit a range of architectural styles, from modern to traditional. With a range of materials, colours, and finishes available, an orangery can be tailored to suit the existing property and the homeowner’s taste.


An orangery extension can provide a versatile and flexible space that can be used for a range of activities, from dining to entertaining to relaxation. With the right furniture and decor, an orangery can be transformed into a comfortable and stylish living space that can be enjoyed year-round.

Increased connection with the outdoors

Homeowners can benefit from the advantages of natural light, fresh air, and views of the surrounding landscape by extending their orangeries to create a stronger connection with the outdoors. An orangery can give the impression of space and freedom by separating the inside from the outside with large glazed panels and doors.

Cost of an Orangery Extension

So, how much does an orangery cost? The cost of an orangery extension can vary depending on a range of factors, including size, materials, and design. Here are some of the critical factors that can impact the cost of an orangery extension:


The size of the orangery extension will significantly impact the cost. More significant extensions require more materials and labour, increasing the overall cost.


The choice of materials for the orangery extension can also impact the cost. High-end materials like hardwoods or bespoke metalwork will be more expensive than standard uPVC or aluminium.


The type of glazing used in the orangery extension can also impact the cost. High-performance glazings, such as low-emissivity (Low-E) or self-cleaning glass, will be more expensive than standard double glazing.

Planning and building regulations

The price of a building permit and building regulations may also impact the overall price of an orangery addition. Some extensions may require planning permission, which can add time and costs. Additionally, it’s essential to follow building codes, which could necessitate additional construction and inspections.

Site preparation

The cost of site preparation, including groundwork and landscaping, must also be considered. The site may need to be levelled or excavated to prepare for the construction of the orangery extension.


The cost of labour for the construction of the orangery extension will also need to be factored into the overall cost. This may include the cost of architects, structural engineers, builders, and electricians.

Although the price of an orangery extension can vary greatly, as a general estimate, one might run between £20,000 and £50,000. The price will vary according to the orangery’s size, composition, design, and any extra features or site preparation necessary. To get a precise idea of the cost of an orangery extension, it is crucial to get thorough quotes from several contractors.

Wrapping Up!

The benefits of adding an orangery to a home can range from more living space and better natural light to higher property values and unique design features. Orangery extensions are a popular choice for homeowners looking to create a stylish and practical living space due to their adaptable design and range of uses.

But before starting an orangery extension project, it’s crucial to carefully consider the cost, the need for a planning permit, and the available design options. You can build an orangery extension that satisfies your needs, increases the value of your home, and appeals to potential buyers by working with a reputable builder and meticulously planning the project.
