Even in large pots, no plant will survive if their roots freeze. Therefore all plants on the balcony I consider to be annual

In a sunny corner of the apartment, we installed floor tiles to resist water damage. In order to help keep the floors clean, we chose rolling wire rack, the type used in many kitchens, to corral the plants into manageable areas of the apartment. The racks also provide the opportunity to act as temporary room dividers, for example they could be stationed around the dining area to create a more green and intimate space.
