The Zollinger roof is an example of a lamella structure, specifically a timber lamella roofing system. It is called so after the German architect, city planner and municipal construction official, Friedrich Zollinger who developed the system.&lt;br /&gt;
&lt;br /&gt;
Although relatively labour intensive to construct by skilled workers, the design had a number of advantages over standard roof designs including the absence of long tie beams or supporting posts, significantly less material required than traditional roofs, it could adapt to openings and could be made entirely of short pieces of timber which could be prefabricated and installed without large machinery.&lt;br /&gt;
&lt;br /&gt;
These types of roofing systems were adopted at times when demand was high but materials and costs were prohibitive, such as between the World Wars. Historical examples of Zollinger roofs can be found in a house in Schweicheln-Bermbeck and Augustinus church in Heilbronn, Germany, whilst modern examples can be found throughout Europe.&lt;br /&gt;
&lt;br /&gt;
Structures that bare great similarity to the Zollinger roof are lamella structures, gridshells, geodesic domes, reciprocal grids and nexograde grid structures.
