Know before you buy
The structure is designed to be mounted against a sturdy, flat exterior wall. You will need to ensure the wall is structurally sound and capable of supporting the greenhouse frame, typically requiring a masonry or concrete surface for secure anchoring.
The greenhouse comes with manual roof, side, and louvered vents. While they are manual by default, optional automatic vent openers can be purchased separately to help regulate temperature without constant monitoring.
No, a foundation is not included. Because the greenhouse needs to be securely anchored to both the ground and your home's wall, you will need to prepare a level base, such as a concrete slab or a perimeter foundation, prior to assembly.
By sharing a wall with your home, the greenhouse benefits from the thermal mass of the building, which helps retain heat more effectively than a standalone structure. This design is particularly efficient for extending your growing season into the cooler months.
No, the greenhouse is sold as the structural frame and glazing only. You will need to source or build your own shelving and staging to suit your specific planting needs.
The Arcadia features both door types to provide flexible access. The sliding door is ideal for saving space and preventing interference with exterior walkways, while the hinged door offers a wider, more traditional entry point for moving larger plants or equipment.
