This picnic shelter for Organic Valley’s CROPP headquarters was installed as part of a demonstration workshop during 2012′s Kickapoo Country Fair. The WholeTrees round timber structural frame has a distinctive half-circle back bent and two branching columns supporting the front beam. Translucent polycarbonate panels protect the shelter from the elements, while admitting light and highlighting the round timber structure.
WholeTrees was commissioned to revitalize this interpretative center’s atrium, replacing the existing 26-foot-tall steel column with a structural black willow tree. WholeTrees also designed and built the round timber staircase leading to the atrium’s mezzanine, alongside functional design elements such as slab wood benches, a 15-foot slab wood bar and built-in shelving made from red and white oak, ironwood and American elm.
This greenhouse at Philadelphia Community Farm is used to start plants for its CSA fields. The structural system is built with black locust timbers, whose rot-resistant qualities are especially useful since greenhouse humidity fluctuates and condensation could potentially corrode less hardy species.
The Albertson Residence’s graceful branched columns and cambered shed roof showcase the incredible strength of round timber framing. With a passive solar design and wall panels pre-fabricated from salvaged materials, its elegance is rooted in simple efficiencies.
The Chrysalis farm house’s branched timber structure was harvested entirely on farm grounds, and skidded to their building site by the resident draft horse. Its straw bale envelope keeps the home warm during harsh Wisconsin winters. An attached solar greenhouse provides food and heat, while incorporating a greywater filtration system.
Located just outside of Chicago, IL, Angelic Organics is the largest Community Supported Agriculture (CSA) farm in America. With office space on the building’s second floor balcony, the ground floor hosts workshops and outreach activities. A structural hybrid of straw bale and round timber, the Learning Center also employs passive energy design strategies for summer shading, winter solar heating, and natural ventilation.
