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]
