Orangeries
The space between.
More substantial than a conservatory, less invasive than an extension. An orangery brings a flat-roofed lantern, brick pillars and full Building Regs comfort to your home.

What's an Orangery?
Conservatory, orangery, extension — what's the difference?
Roughly: a conservatory is mostly glass, an extension is mostly brick, and an orangery sits between — brick around the edges with a glazed roof lantern.
| Conservatory | Orangery | Extension | |
|---|---|---|---|
| Construction | Mostly glass | Brick + glazed lantern | Mostly brick |
| Roof | Glass / poly / warm roof | Flat with glazed lantern | Tiled or flat |
| Building Regs | Sometimes | Usually | Always |
| Year-round use | Best with warm roof | Yes | Yes |
| Cost band | £ | ££ | £££ |
| Best for | Garden room feel, lower budget | Design-led upgrade | Maximum space, full integration |
