the faux-rusted facade of this office building - a branch of la caixa, a catalán bank - sits on top of what appears to be a much older building. a perpendicular wall sprouts colorful vines and foliage.

it makes me think about the idea of urban vertical farming or just basic city beautification.

it seems the most successful public works projects bring nature back to urban spaces. and this, even though it is a private endeavor, makes everyone stop and look - and what’s more, inspires a sense of sustainability and diversity of life. no need to repaint a big, ugly concrete wall for a new look. just replant.
