If you are planning a glazed extension, you might be wondering about the difference between an orangery and a conservatory. While they both create light-filled spaces, their design, structure, and use can be quite different. Choosing the right option depends on your style, budget, and how you want to use the room.
What Is a Conservatory?
A conservatory is typically a structure made mostly of glass. It has a lightweight frame and a glass or polycarbonate roof. The walls are usually more than 75% glazed. This design maximises sunlight, making the space feel open and connected to the garden.
Conservatories are ideal for seasonal use or as bright living areas. However, because of the large glass surface area, they can be harder to heat in winter or keep cool in summer without the right glazing.
What Is an Orangery?
An orangery combines solid walls with large windows and a partly glazed roof, often with a roof lantern. Traditionally built with brick or stone bases, modern orangeries use hardwood or aluminium frames alongside high-performance glazing.
The solid walls make orangeries feel more like an extension of the home. They provide better insulation, more privacy, and a sense of permanence. A traditional hardwood orangery can be used comfortably all year round as a kitchen, dining area, or living space.
Key Differences Between Orangeries and Conservatories
1. Structure and Materials
Conservatories – lightweight frames, mostly glass walls and roof.
Orangeries – mix of solid walls and glass, with a brick or stone base and a lantern-style roof.
2. Thermal Performance
An orangery’s solid walls and insulated roof make it easier to heat and cool. Conservatories can achieve good efficiency with modern glazing, but they require more climate control.
3. Appearance
Conservatories look more like garden rooms, with clear views in every direction. Orangeries have a more architectural style and blend seamlessly with the house.
Which Should You Choose?
If you want maximum sunlight and a more affordable option, a conservatory could be right for you. If you prefer year-round use, a higher level of privacy, and a space that feels like part of your home, an orangery is a better choice.
Our team at Glass House Architecture can help you design either option, tailoring the materials, glazing, and layout to suit your property.
Cost Considerations
Conservatories are usually less expensive due to lighter construction and fewer solid materials. Orangeries cost more but often add greater long-term value to the property.
Blending Styles
Some homeowners choose designs that combine features of both. For example, a conservatory with a solid roof or an orangery with larger glazed panels. This approach offers the openness of a conservatory with the comfort of an orangery.
Conclusion
Both orangeries and conservatories can enhance your home. The right choice depends on how you want to use the space, your budget, and your home’s style. Whether you prefer the airy feel of a conservatory or the solid elegance of an orangery, careful design will ensure your extension is beautiful, comfortable, and practical.
