New Expansion of the Hamburg Stock Exchange
The building has a grid spacing of 4.14 metres square. The pillars are spanned by semicircular transverse arches; above these lie masonry vaults. If such structures are damaged, the risk of collapse is very high. Reconstruction was further complicated by the fact that the vault structures, transverse arches, and pillars had been exposed to the elements for almost seven years. After Hall II was initially restored, work could begin on the expansion of Hall I, which houses the stock exchange.
