Denizens of Milan, Italy will have a brand new 2.5 acre forest smack in the middle of their city by the end of 2013. You might think that’s a city with its priorities straight. But this particular forest didn’t require the sacrifice of precious commercial real estate—because it’s of the vertical variety.Brainchild of Italian architecture firm, Stefano Boeri Architetti, the Bosco Verticale(literally, “vertical forest” in English) is two residential apartment buildings peppered with cantilevered terraces. Each terrace is specially designed and engineered to support a small community of trees, shrubs, and other greenery.
When complete, Bosco Verticale will house 730 trees from three to six meters (10 to 20 feet) in height and irrigated primarily by the buildings’ grey water—runoff from baths, sinks, washing machines, and dishwashers. 5,000 shrubs and 11,000 plants will keep the trees company. A true forest.
Milan is the second biggest city in Italy and one of the most polluted in Europe. Bosco Verticale, an “anti-sprawl measure,” is intended to set a new course for the fashion capital. Vertical green spaces expand biodiversity without expanding city limits.
Trees and other green things filter dust and carbon dioxide and breathe out fresh oxygen. They’ll also produce humidity and shield residents from city noise. Along with all that, of course, they’ll bring a touch of nature into central Milan.

Further, engineers had to calculate the weight of the trees, containers, and soil and appropriately reinforce the concrete terraces. Each tree container is lined with a waterproof membrane, a root barrier, and a polypropilene grid to avoid leakage and keep roots away from walls.
Ultimately, the only way to fully vet the design is in practice. But if all goes to plan, tenants will soon retire to their apartments after a long day in the grit and grime and drift off to the sound of wind in the leaves—and muffled car horns.
Also I don't think the tenent's will be pruning the trees it looks like the buildings are sealed off so that would be done by the same crews that would normally be washing windows. The only thing you mentioned that may be a problem would be falling debris.

A tree built out of trees. Something Dubai would do or vegas. A green skyscraper still looks like a box. Wheres the creativity?
The Greek geographer Strabo, who described the gardens in
first century BC, wrote, "It consists of vaulted terraces
raised one above another, and resting upon cube-shaped
pillars. These are hollow and filled with earth to allow
trees of the largest size to be planted. The pillars,
the vaults, and terraces are constructed of baked brick
