The specification file
Canopia Bella 8 × 12
The door and panel schedule make this a meaningfully different comparison from the Balance, despite the same advertised size. Check the 171 cm doorway height carefully for comfortable access.

Do not reduce the panel schedule to one number
Calling this simply a 6 mm greenhouse would hide the separate 4 mm door and window specification. When comparing replacement parts or glazing, record each part of the envelope rather than carrying the roof thickness over to every panel. Confirm that any replacement part is listed for the exact model and revision.
Curved geometry changes the calculation
The bell-shaped envelope is not the rectangular-wall, straight-roof shape used by our gable panel-area tool. That calculator would give a neat-looking answer to the wrong geometry. Obtain a panel schedule or measured developed surface area before using it for material ordering or a heating calculation.
Access is more than floor area
The stated 118 cm doorway width can be useful for moving broad items, but it must be considered alongside the stated 171 cm height. A shortlist based only on 8 × 12 floor area would miss that constraint. Map your actual route from storage to greenhouse and verify the final installed threshold and clear opening before purchase.
