This paper describes the work of Ramboll Computational Design during the design and construction of the Ongreening Pavilion timber gridshell. The structural approach involved form-?nding bending-active timber laths, connected at intersections to form a doubly curved shell. The resulting form was simple to fab-ricate and assemble, realised using 6.5mm thick Finnish birch plywood laths that could achieve high curvature while maintaining desired strength. Due to the ran-dom nature of the ?nal lath topology, the resulting structure was extremely stiff in spite of its low material weight, acting similarly to a continuous monocoque. The fully demountable shell was ?rst erected at Ecobuild 2014 in London.
