Design steel frame for a bench in city garden

I need a creative and practical design for an outside bench

Classical benches which you find in parks consist of 3 cast iron supports on which stripes of wood are attached.

I'd like to make a contemporary version to be placed in very small city gardens with similar look as the old classical bench but with bended metal instead of cast iron. City garden are always very small, hence I'd like to add features to it: storage and flowers

Since bended metal allows any shape, I'd like to have it designed in a way that on the back of the bench, a long planter is integrated and in the front, 2 drawers are integrated for storage.
