Answer
Do garden rooms get condensation?
Not when built properly: insulation, ventilation and the right glazing manage moisture.
In short
A poorly built one can, but a properly designed garden room does not. Good insulation, a breathable build-up, controlled ventilation and the right glazing manage moisture so the room stays dry and usable year round. It is one of the things that separates a proper garden room from a cheap kit.
