Project background

The gridshell is constructed from four layers of alternating lathe, finger jointed to enable use of locally sourced small section green chestnut. The requirement for the gridshell to support the frameless glazing meant that the usual method of construction which allows the gridshell to ‘find its own form’ and to be able to flex was inappropriate. This grid needed to be predicatable and rigid, while specially designed node clamps allowed for small amounts of settling in movement. A further complication was that the design required the lathes to bend over tighter radii than they would naturally go. For more details of this gridshell, see the case study on this project.
