Conservatories vs Orangeries vs Extensions

Not Sure Which Is Right for You? Discover the key differences between conservatories, orangeries, and extensions — and find the perfect fit for your home

What’s the Difference?

Each type of home addition offers its own benefits — from bright glass-filled conservatories to solid, fully integrated extensions. Here’s a quick overview to help you decide what’s best for your home, lifestyle, and budget.

Conservatory

 

  • Lightweight structure with mostly glass walls and roof.

  • Floods your home with natural light — perfect for relaxing spaces or garden rooms.

  • Most affordable option and typically doesn’t require full planning permission


 

Orangery

 

  • More solid than a conservatory, with brick pillars and a flat roof featuring a lantern.

  • Provides a cosy, year-round room with a luxury feel.

  • Excellent balance between light and thermal efficiency


 

Full Extension

 

  • Built as a full structural addition, often matching the main house walls and roof.

  • Seamless integration with your home — ideal for kitchen diners or living spaces.

  • Usually requires building regulations and may need planning approval
