The INSIDE\OUT pavilion is the first architectural gridshell, that utilizes so called “asymptotic curves” on a minimal surface design. This new construction technique enables a simple fabrication and construction process: All lamellas can be fabricated as flat and straight elements. They are elastically bent during the construction process. All joints are identical and meet at 90 degrees.

The design is based on a catenoid – the minimal surface between two circles. By adjusting the position and shape of these two boundary curves, an architectural space was designed, that adjusts to the green islands of this courtyard.

The grid structure is constructed from 1000 m of 1.5 mm thick and 100 mm wide stainless steel lamellas. It spans an area of approx. 90 m² and has a surface weight of only 18 kg/m², a total of 1,6 tons. INSIDE\OUT was built in September 2017 for the 150th aniversary of the TUM.


The construction itself relies on very simple processes. The lamellas are cut straight and flat, and can be easily transported. They are slotted together by hand into flat segments. These segments are bent into their curved geometry. By fixing every node to 90 degrees and adding extra cable supports, the shape is stiffened in its final geomery.
