A backyard room built for every season.

When you want a greenhouse that truly stands up to the calendar, the Four-Seasons Grand Retreat answers. Its reinforced aluminum frame is engineered for wind and snow, and its UV-protected polycarbonate panels hold warmth through cold months and temper the sun in summer. At a commanding 10×12, it’s less a greenhouse and more an outdoor room you can use all year.

Line the walls with plants, add a chair and a heater, and you have a winter refuge and a summer garden room in one. This is the structure for the gardener who’s ready to make their sanctuary the centerpiece of the yard.
