The Lamella roof (also sometimes called the "Zollinger roof" for its inventor Friedrich Zollinger, a municipal building surveyor from Merseburg in the German state of Saxony-Anhalt [1] ) is a construction type where the roof is supported by an arched network of overlapping lamellae in rhombic form. [1] As such it may be understood as a subset of gridshell type roof constructions.

This roof style was designed by Zollinger to satisfy urban expansion needs, where material costs made new construction cost-prohibitive, but existing buildings couldn't support additional stories by adding further masonry walls and high-pitch trusses [2] . The vault system comprises short structural members interwoven across a curved surface in a diamond pattern. [3] [4] Lamella structures can be constructed of wood timber or lumber, concrete, or metal. [5] Modern versions of this type of structure include glazed metal-framed systems referred to as "transparent shells." [6]
