Stefano Boeri loves putting trees on the outside of buildings.

First, there was his award-winning build design in Milan, Italy known as Bosco Verticale ("vertical forest"), which was unveiled last October. A month later, Boeri revealed "The Tower of the Cedars" in Lausanne, Switzerland.

Now he's back with his third plant-covered structure, the Mountain Forest Hotel, a 250-room hotel located in Guizhou, China.

Like his past projects, the Mountain Forest Hotel will be built with sustainability in mind — it's a way to clean up the surrounding air and inject some green into a landscape of steel and concrete.

Plants will cover the building from its foundation to its roof. Almost the entire structure will feature trees and shrubs.

Ultimately, Boeri says he wants to meld his tree-covered buildings with nature.

"Symbiosis is the goal," he explains on his website. Instead of designing buildings that live outside their natural environment, Boeri wants to weave them into the larger ecosystem. The hotel will feature a gym, bar, lounge, VIP area, conference room, and restaurant, Boeri says. His firm will also partner with a local artist named Simon Ma for the interior design.

Ma will have some tough competition to make the inside outshine guests' first impression.
