Sappi

German firm baumraum, led by architect Andreas Wenning, recently built The Treehouse as a spot for businesses to work on ways to improve the planet's future. The idea began when Sappi, an international paper maker, and their communication's agency, Proximity BBDO, banded together with The Flemish Forest and Nature Agency and the city of Hechtel-Eksel to form a partnership that would encourage companies and organizations to become more sustainable during their daily practice. The result is The Treehouse, which is outfitted as a "state-of-the-art eco facilities located in the forests of Hechtel-Eksel, Belgium."
