Metcalfe worked with Morris Arboretum to craft a unique treetop experience - a place to learn from nature. The exhibit extends along 450 feet of elevated pathways within the arboretum’s forest. Our design balances perceived danger, actual safety, beautiful materials, and real trees. A visitor favorite is the “Squirrel Scramble,” an open-net climb suspended 50 feet above the ground where visitors can play and lounge in the forest canopy. “[Out on a Limb] makes you see the world in a new way... [Metcalfe applies] time-honored architectural tricks to enhance nature’s drama—opening up a wide vista here, compressing the focus over there, while frequently testing our fear of heights. The result is a space that exerts an irresistible allure, to young and old alike.” -Inga Saffron, architecture critic, Philadelphia Inquirer 2015 Mid-Atlantic Association of Museums - ”Buildy” Award 2012 International Galvanizing Awards - Highly Commended 2010 AIA Pennsylvania - Architectural Excellence Award 2010 AIA Philadelphia Awards for Design Excellence - Gold Medal Award 2010 American Association of Museums - Excellence in Exhibition Design Award 2010 International Making Cities Livable Design Awards - Green Places Award 2010 Best of Philly® Awards
