Camp Graham / Weinstein Friedlein Architects

At a lakeside camp, where tented and cabin campsites are proven attractions, the Girl Scouts set out to add a different sort of shelter. They wanted treehouses, something to evoke the sense of adventure, fantasy, delight found in the lofty constructs of backyards and forest getaways. The new 36-person site at Camp Graham consists of a series of pole structures along the wood’s edge, linked by an elevated path that winds among the trunks of the native trees. The challenge in treehouse making is to build without doing harm to the trees, and to extend access to all campers.
