Many Palram-Canopia products are made from a Modular Design. This means the product will arrive in several modules/units and are assembled into one unit.
For example, the Balance 8' x 20' Greenhouse will come as one 8' x 8' unit, with three 8' x 4' extension pieces, and is assembled into one larger unit.
The smallest size is the base unit, and the larger sizes add extensions/modules to the initial unit.
For Module System units, the order will arrive labeled as the smaller sizes of the product, and they are assembled into the larger size desired.
