The 'Gridshell' project undertaken within MakeLab 2011 was based around a custom designed, low cost CNC fabrication process used to build a double curved timber grid shell. Grid shells are single and/or double curved surfaces that transfer compression forces in the plane of the
surface through a network of linear elements. They are materially efficient structures and work best if the surfaces have double curvature, but this also makes them difficult to build. The key aspect for fabrication is translating the design data from the computer to the actual material, which for in this project was achieved using an automated CNC marking device. The workflow based around this device allowed the workshop participants to design and build a full scale timber grid shell in a very short time.
