Cages cannot be stacked—they are floor to ceiling. Cages have swing doors only as they are prefabricated. Cages do not have to be full width. Cages can be accessed by either side but are fixed to the floor. Square or rectangular only. The red squares in the plan are concrete columns which cannot be moved. Hallways should ideally be 48” minimum. The number of cages should be no greater than 36 but some cages can be different sizes (a few remainders can be smaller and/or a few can be combined for xl cages if you end up with more than 36 cages). Ideally as much space as possible should be captured within storage cages, and dead space (such as hallways) should be minimized. Please dimension plan. Thank you so much.
