Floor/facade

1920-1940



An innovative method of sheet glass production (by means of drawing) that appeared in the 1900s led to larger/wider windows.

The closing up of large window cavities required the use of iron beams, which became commonplace within a few decades and especially in the 1930s, where buildings on the whole were characterised by their extensive use of iron structures in exterior walls, typically in bay windows and balconies.
