Prefab 4-Season Backyard Rooms — Garden Room Series
What is Garden Room?
Garden Room is a line of modern prefab 4-season backyard rooms available in 118 and 158 sq ft. Designed for North American homeowners, each unit ships as a flat-pack kit and assembles in days — serving as a backyard home office, gym, studio, lounge, or private retreat. The Garden Room Series starts at $19,990 USD and ships to the United States and Canada.
Why homeowners choose Garden Room.
Traditional home additions take months and require permits, demolition, and major budget. The Garden Room Series brings the same livable square footage to your backyard — finished, delivered, and ready to use. See the full comparison →
