If you’re looking to add extra space to your home, you’ve likely considered either a garden room or a conservatory. Both can be great options — but they serve very different purposes.
Here’s a clear comparison to help you decide which solution is right for your lifestyle and property.
What is a Garden Room?
A garden room is a standalone structure built within your garden. It’s fully insulated and designed for year-round use, making it ideal for:
Home offices
Gyms
Studios
Guest spaces
Relaxation rooms
Garden rooms feel more like an extension of your home rather than a seasonal add-on.
What Is a Conservatory?
A conservatory is an extension attached to your home, typically made mostly from glass. They are commonly used as:
Dining areas
Sunrooms
Relaxation spaces
While visually appealing, conservatories can struggle with temperature regulation.
Key Differences at a Glance
Temperature Control
Garden Room: Fully insulated, usable all year
Conservatory: Can be too hot in summer and cold in winter
Planning Permission
Garden Room: Often falls under permitted development
Conservatory: More likely to require approval
Cost
Garden Room: £8,000–£30,000+
Conservatory: £10,000–£40,000+
Installation Time
Garden Room: 2–4 weeks

Flexibility
Garden Room: Separate, quiet, multi-purpose

Which Adds More Value?

Modern, Luxury Design Options
Final Verdict
If you want a year-round, flexible, modern space, a garden room is usually the better choice.
If you want a light-filled extension mainly for warmer months, a conservatory may suit.
