An abstracted version of a street tree, a canopy of tessellated irregular polygons balances atop slim steel posts.

When Public: Architecture + Communication visited the site of the transit shelters the University of British Columbia had asked them to design, they found that something was missing. The main point of entry to the campus, University Boulevard is lined with trees—except where the bus shelters would go. “There was this language of gaps that we noticed,” said Public’s Christopher Sklar. The shelters themselves, they decided, should fill in the tree line. The designers were left with a question, articulated by Sklar: “How does it be a quiet piece but also something interesting and unusual that relates to its surroundings?”

StructureCraft fabricates an orchid-shaped roof that supports vegetation and Living Building Challenge principles.

After serving patrons at one of Vancouver’s oldest botanical gardens for nearly 100 years, the VanDusen Gardens Visitors Centre had fallen dangerously into disrepair. Perkins+Will Canada conceived of a new, orchid-shaped center that meets CaGBC’s LEED Platinum ratings, and is the country’s first structure to target the International Living Building Challenge with features like geothermal boreholes, a 75-square meter photovoltaic array, and a timber roof that supports vegetation. To help fabricate the wooden structure to Perkins + Will Canada’s vision, the team contracted StructureCraft, a Vancouver-based design-build studio specializing in timber craftsmanship and structural solutions.

Initial designs for the 19,000-square-foot building were delivered to StructureCraft as Rhino files. The uniquely shaped rooftop, which mimics an outline of the indigenous British Columbia orchid, had to be economically fabricated in a way that took net carbon effects into account. Within Rhino plugins—mainly Grasshopper—and with the help of strucutral engineers Fast + Epp, the StructureCraft team sliced the shape of the building into 71 long, curved panels of repeatable geometries. “Each curve is unique, so there’s a different radii for each beam,” said Lucas Epp, a structural engineer who worked on the project. “We optimized the global geometry of the roof so the radii of all the beams were in our fabrication tolerances but still achieved the architect’s desired aesthetic.” Read More
