It's a good idea to see a garden room on two before you buy. One way of doing this is to visit a show where garden room suppliers are exhibiting their work.
The key show for seeing several garden room designs in one visit is Grand Designs Live. This show takes place twice a year, once in London and then again in Birmingham.
As well as being able to see several garden room designs up close, visiting a show also has the added benefit of snapping up a bargain as many suppliers run promotions during the show.
