This nine story apartment building in Bogotá, Columbia is clad almost entirely in beautiful green walls. The large project is a collaboration between builder and designer Exacta Proyecto Total, Paisajismo Urbano and Groncol. In a dense area like this, I would imagine also the neighbours to be delighted about the green walls. The whole system is pretty impressive and the video is very informative about the benefits of the living walls.
George Irwin has written many excellent articles about the different qualities of green walls. On top of reading about the benefits of a green wall, it is also interesting to learn about the challenges of maintaining a green wall.
