A cellular structure, in particular a supporting or sound insulation structure plantable with greenery, one with earth, rock, or bulk material filling (Ed), arranged in particular as cells (Z) in layers, the cells being bounded at least in part by flat flexible, liquid-permeable, and corrosion-resistant material (F), in particular material in the form of netting or a grating, and having at least one dimensionally stable frontal element (FG) also in the form of netting or a grating which is connected to tension bracing (ZA) extending into the cell filling and to support bracing (ZV) ensuring the assigned frontal surface inclination and frontal surface position of the structure, the support bracing (ZV) for the individual front elements having at least one elongated bracing element (AS) which on one side is connected to a front element (FG) and on the other extends into the area of the filler.
