When homeowners across the UK start thinking about extending their living space, two options often come up — orangeries and conservatories.
While they might look similar, their structure, insulation, and cost can be quite different. Choosing between the two depends on your budget, home style, and how you plan to use the space.
Let’s break down the differences so you can decide what’s right for your home.
🧱 What Is an Orangery?
An orangery is a brick-based extension with large windows and a partially solid roof (often with a glass lantern).
Originally used to grow citrus trees in grand estates, today’s orangeries are designed as year-round living spaces — perfect as dining areas, home offices, or lounges.
Main features:
-
Solid brick pillars and walls
-
Flat roof with a glazed lantern
-
Better insulation and soundproofing
-
Feels like a natural extension of the house
Average cost (UK 2025): From £25,000 to £50,000+, depending on size, glazing, and materials.
🌿 What Is a Conservatory?
A conservatory typically has a fully glazed roof and mostly glass walls, creating a bright and airy space that feels connected to the garden.
It’s ideal for those who want a light-filled space at a more affordable price.
Main features:
-
75% glass roof and 50% glass walls (minimum by UK definition)
-
Lightweight frame (uPVC, aluminium, or timber)
-
Often doesn’t require full planning permission
-
Perfect for enjoying sunlight and garden views
Average cost (UK 2025): From £20,000 to £50,000, depending on size, glass type, and frame material.

|---|---|---|
| Insulation | Excellent (brick + roof lantern) | Moderate (mostly glass) |
| Natural Light | Moderate | Excellent |
| Year-round Use | Yes | Often seasonal |

💡 Which One Should You Choose?

-
Choose a conservatory if you want to enjoy light, space, and garden views without major construction costs.
