While conservatories may be the first product to spring to mind when you think of extensions, orangeries offer a compelling alternative, depending on what you’re looking for.

Originating in the 17th century, modern orangeries are thermally efficient spaces that feel like a natural extension of your home rather than a separate area. They feature more robust brick walls than their predominantly glazed counterparts and are often topped with a flat roof and a lantern, allowing natural light to flood in from all angles.

As a structure, orangeries are highly thermally efficient, providing similar energy performance to the rest of your property. This makes them ideal for use as additional living rooms, offices, gyms, or other functional spaces.

They also rarely require planning permission, making them a straightforward choice for homeowners looking to add both value and enjoyment to their property.

What is an orangery?

An orangery is a type of home extension that sits somewhere between a conservatory and a traditional brick-built extension.

Its defining feature is a flat roof, often accompanied by walls with solid brick bases, and expansive glass panes rising above. The combination of solid structure and expansive glazing creates a room that feels integrated with the main house, offering a bright, welcoming space all year round.

Key features of orangeries include:

  • Low brick base or brick pillars supporting the structure
  • Solid roof sections combined with a central glass lantern or fully glazed roof
  • Tall windows or large windows for maximum natural light
  • Roof lanterns that bring in daylight without compromising thermal efficiency
  • Ability to be customised to suit both period properties and modern architectural styles

Orangeries are versatile, whether you want a bright open-plan living space, a garden room, or a dedicated home office. The combination of solid walls and large glass areas ensures excellent climate control, so your new space is comfortable year-round.

What are the benefits of orangeries extensions?

Orangeries offer a number of advantages that make them a popular choice for UK homeowners:

Abundant natural light

Thanks to the central glazed lantern and tall windows, orangeries flood your home with daylight, creating a welcoming atmosphere and connecting indoor spaces with your garden.

Versatile living space

Whether you want a kitchen extension, office, reading spot, dining area or seating area, a new orangery provides functional extra living space that works with your lifestyle.

Energy efficiency

Modern orangeries use thermally efficient glazing and multi-chambered frames, helping to retain heat in winter and keep rooms cooler in summer. This improves comfort and reduces energy bills.

Aesthetic appeal

Orangeries combine traditional extension features with contemporary design, offering timeless appeal that can complement both period properties and modern homes.

Property value

A well-designed orangery can add significant value to your property, making it attractive to potential buyers while upgrading your home’s overall appearance.

How do orangeries differ from conservatories?

Feature Orangery Conservatory
Structure Solid walls with a brick base or pillars Mostly glass walls
Roof Flat roof with central glazed lantern or roof lanterns Pitched glazed roof
Thermal performance High, with solid roof sections and multi-chambered frames Dependent on the materials used
Appearance Feels like a premium extension Dependent on the style you choose
Glazing Large windows and a roof lantern Full glass walls and an optional glass roof
Planning Often, within permitted development rights Often the same, but it depends on size and style

The main difference is that orangeries combine solid walls with roof lanterns, whereas conservatories are predominantly glass.

FAQs

Do I need planning permission for an orangery?

Most single-storey orangeries fall within permitted development rights, meaning planning permission is usually not required. However, if your property is in a conservation area or you plan to exceed size limits, it’s always best to check local building regulations first.

How does an orangery compare to a conservatory?

Orangeries have solid walls and a flat roof with roof lanterns, offering better thermal efficiency and a more substantial feel. Conservatories are mostly glazed, with pitched roofs and less insulation.

Can I choose different colours and finishes?

Yes, our orangeries can be fully customised with your choice of frame colours, glazing, and decorative features to suit your home’s style.

Are orangeries energy efficient?

Absolutely. With thermally broken frames and high-performance glazing, your new orangery keeps heat in during winter and reduces heat gain in summer.

What can I use my orangery for?

The space is flexible: open-plan living, garden rooms, kitchen extensions, dining areas, or home offices, all tailored to your lifestyle.
