Conservatory vs orangery explained

Conservatory vs orangery is the debate most homeowners will have once they’ve decided to add an extension to their home. Both are good options, but whilst they may look similar, there are subtle differences that mean they actually give you two very different home experiences.

Conservatories feature a higher percentage of glass, with tall windows that make up most of the structure. Available in various shapes and styles, you also have the choice between a glass and tiled roof when you choose Unique Glazing.

Orangeries, on the other hand, feel more permanent; adding an orangery is essentially adding an extra room to your ground floor. They are built using more bricks, with a high brick base, and with pillars often splitting up the windows. At the crown, you’ll find a flat roof with a lantern on top to attract sunlight from all angles.

We’ll explore the two in more detail below and explain which may be better suited to your home based on your unique priorities and demands for the space.

What is a conservatory?

As mentioned above, conservatories are the right choice if you’re looking for a light-filled extension. Whilst we’ve all experienced chilly afternoons in a family member’s condensation-filled conservatory, you don’t need to worry about this anymore thanks to modern uPVC frames and energy-efficient glazing.

With origins dating back to the Victorian era, conservatories nowadays have largely ditched the polycarbonate materials that caused such extreme temperature swings, and are now comfortable spaces that can be used whatever the weather.

Today’s designs are far more energy efficient than older models, using advanced double glazing and insulated frames to reduce heat loss and improve temperature control. Glass or tiled roofs are available from Unique Glazing.

How to tell a conservatory apart from an orangery

• Predominantly a fully glazed structure
• Features large windows and often a pitched glazed roof (this is the most common Victorian style)
• Minimal brick structure, usually a low wall at the base
• Designed to maximise natural light
• Lighter, more open appearance

What is an orangery?

Orangeries date back to the 17th century, when they were built to protect citrus trees and exotic plants during colder months in northern Europe. Today, they’re viewed as a more substantial extension that can be used in the same manner as any other room, be it a home office, additional lounge, kitchen or even an additional bedroom to host a lodger.

A new orangery typically includes a brick structure, tall windows, and a flat roof with a central roof lantern. This creates a bright yet cosy space that feels more like part of the main house.

How to tell an orangery apart from a conservatory

• Greater use of brickwork and solid structures
• Flat roof with a roof lantern or partially glazed sections
• Less glass overall, creating a more enclosed feel
• Stronger thermal performance and climate control
• Designed to feel like a permanent room extension

Conservatory vs orangery: Which should I choose?

Both options can transform your home, whether you’re creating a garden room, dining area, or even a home gym. The right choice depends on how you plan to use the space and your priorities around light, insulation, and budget.

Choose a conservatory if

• You want maximum natural light and garden views
• You love the idea of a bright, airy space for relaxing
• You’re working with a tighter budget
• You enjoy features like a glass roof for stargazing or birdwatching

Choose an orangery if

• You want a space that feels like part of your main house
• You want the best extension possible for thermal performance
• You prefer a more private, enclosed environment
• You’re planning a kitchen extension or home office
• You like elegant design features with a solid roof

Key differences at a glance

Conservatory vs orangery: what else do I need to consider?

Before deciding, there are a few practical factors worth thinking about.

Planning considerations

In many cases, both conservatories and orangeries fall under permitted development rights, meaning planning permission isn’t required. That said, it depends on your property, especially if you’re in a conservation area or dealing with specific local regulations.

We guide our customers through this process and handle any requirements with local authorities, so you’re never left guessing.

Build complexity

Conservatories are generally quicker to install due to their lighter structure. Orangeries involve more brickwork and construction, which can increase build time and complexity.

Costs

Costs vary depending on size, materials, and design choices. Features like roof lanterns, underfloor heating, frame colours, and glazing options all play a role. Orangeries are usually more expensive, though both options are bespoke when you choose Unique Glazing, so you stay in control of your budget.

Frequently asked questions

Do I need planning permission for a conservatory or orangery?

In most cases, no. Many fall under permitted development rights in London, though this depends on factors like size, exact location, and local regulations. We always recommend checking, and we’re happy to help guide you through the process.

Which is warmer: a conservatory or orangery?

Modern conservatories are highly energy efficient, though orangeries tend to retain heat better due to their solid roof and brickwork. Both are comfortable year-round with the right glazing and design.

How long do they last?

With quality materials and proper installation, conservatories can last 25-35 years in peak condition, while orangeries can last 30 years or more. They both promise to increase your property value, as they really appeal to potential buyers.
