The Center of New Industries and Technologies (French: Centre des nouvelles industries et technologies,
better known as the CNIT), located in Puteaux, France, is
one of the first buildings built in La Défense in Paris, France.
It functions as convention center, though it also houses the main offices such as that of FNAC, a media and electronics retailer found throughout Paris, as well as a Hilton hotel.
The initial construction of the building took place between
1956 and 1958.
Its architects were Robert Edouard Camelot, Jean de Mailly, Bernard Zehrfuss accompanied by the engineer Jean Prouvé for the exterior.
This building is notable for being the largest unsupported concrete span enclosed space in the world.
Its triangular structure is supported on three points that are two hundred and eighteen meters (715') apart.
The centre of the roof is more than forty six meters (151') above the ground. Situated on the northern side of the La Defense plaza,
this is one of the most eye catching buildings in modern architecture, being constructed of steel reinforced concrete in an innovative double shelled design.
Internally, the impressive vaulted roof is entirely unencumbered by columns or girders and the buildings within the space provide no structural support whatsoever, seeming rather to hang from the span itself.
A
major refurbishment of the CNIT was finished in summer 2009 increasing the public space within the building by the addition of a lower floor containing new shops and restaurants.
Sadly during this work, some of the original features of the design, including the striking triangular door handles that copied the shape of the building were lost to more modern but otherwise unremarkable fittings.
