The continuous improvement in the processing of iron and concrete during the Industrial Revolution opened up new and previously undreamt-of potentials for architects and engineers.
Architectural potentials increased with the use of iron, whose quality continuously improved during the Industrial Revolution. Using iron and glass it was possible to construct buildings like the translucent Palm House in Kew Gardens (1848) and the even more famous "Crystal Palace" built by Joseph Paxton in 1851. Paxton used prefabricated panes of glass with iron or wooden structural supports: a forerunner of the standard industrial buildings in the 20th century.
A second new material used by architects from 1867 onwards was reinforced concrete, a compound material first developed by a French gardener called Joseph Monier for garden tubs. Thanks to steel reinforcement bars or fibres integrated into the concrete to take up the stress and resist compression, it became possible to construct gigantic cantilever domes from the resulting compound. The start of the 20th century saw a steady increase in the amount of factory buildings, bridges and houses built of reinforced concrete.
Around this time the contrast between engineers and architects – between functional building and building art - came to a head. During the 19th century the profession of "civil engineer" had developed in Great Britain. This was a person who was not only versed in engineering above and below the ground, but also in factory engineering equipment. One of its most prominent representatives was Sidney Stott, who began his career by building multi-storey spinning mills in the Manchester region, and was later responsible for building textile factories in the border region around north-west Germany and the Netherlands.
As a reaction to this, more traditional architects preferred to refer back to the craft qualities and building arts of the mediaeval age. At the end of the 19th century the arts and craft movement exerted considerable influence in Great Britain; and in France, Eugène-Emmanuel Viollet-Le-Duc analysed Gothic construction principles. "Jugendstil" flourished above all in Germany and Austria – even in industrial buildings like the engine house in the Zollern colliery in Dortmund.
At the start of the 20th century a group of committed architects got together in Germany with a common idea of combining artistic design with modern materials and functional construction. The pioneer was a man named Peter Behrens, who served on the artistic advisory committee of the gigantic AEG power company from 1907 onwards. In Berlin he constructed a turbine factory from concrete, steel and glass. Functionally it was a long open production building with windows stretching to the roof; and yet it was designed with a feeling for tradition, with massive corners and powerful pillars.
His colleague, Walter Gropius, further developed this concept in 1911 in the form of the "Fagus works", a shoe last factory in Alfeld. He designed the complete facade with glass windows filled with thin iron frames supported by narrow brick mullions. In this way he was able to give the building an impression of transparency and lightness. The corners of the administration building have since become an icon in modern architecture: they consist completely of glass windows without corner pillars, because Gropius shifted the structural supports to the inside of the house. Using this as a starting point he was able to develop an uninterrupted expanse of clear glass known as the "curtain wall", one of the most influential forms of architecture in the 20th century.
The most radical solution in industrial building was invented in the USA. In 1908 Albert Kahn built a factory near Detroit for the Ford motor works which was absolutely suitable for conveyor-belt work: a long hall at ground level, in which all manufacturing steps could be conducted in sequence, and cars could be put together from pre-pressed pressed steel parts in a short amount of time. The building could be extended with new modules when required.
