This roof style was designed by Zollinger to satisfy urban expansion needs, where material costs made new construction cost-prohibitive, but existing buildings could not 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]
