Apart from three new guardhouses a new roof above the North Gate was built as part of the redesign of the North Gates 9 and 8 of the Frankfurt Fair. The design of the German architect Ingo Schrader for the guardhouses and the roof resulted from a competition in 2008.
The roof of the North gate was placed on an existing road bridge. The basic geometry of the 40 m long by 20 m wide oval consists of various individual flat steel bars. Position and dimensions of the flat steel were developed using a computer-based optimisation algorithm. The roof is supported by triangular shaped steel columns.
