Working from Tokyo, Paris and New York, Japanese architect Shigeru Ban is already considered to be one of the major architects of the 21st century. A pioneer in the field of sustainable construction ‒ particularly through his use, from 1980, of compressed paper ‒ Shigeru Ban believes that using this brings architectural creation into the present day. His construction of an infant school in Chengdu in less than a month, following the earthquake there, is one of the most striking examples of this.

In his study entitled "Living Bridges", Marc Mimram introduces us to 4 bold projects as ways of reconsidering infrastructure. By operating his business simultaneously as a design office and architecture-engineering firm, Marc Mimram invites people to restore meaning to urban infrastructures and to "lay the city down again". The bridge has a role which goes beyond its original use of crossing from one bank to the other and Ductal®'s qualities of high resistance and thinness come into their own.

Ma has created several award-winning and famous projects with MADA SPAM, including the Longyang residential complex in Shanghai, the Silk Tower in Xian, the CCTV headquarters in Beijing and the Stock Exchange in Shenzhen. He has taught architecture in China and in Europe, and he is the new Dean of the University of Southern California School of Architecture. He defines architecture as a work that goes beyond boundaries and that can't limit itself to construction...

A senior partner for FXFOWLE Architects, Sudhir Jambhekar works currently on multiple towers in India, the United Arab Emirates, China, Japan, Korea, and on the Dubai's Sheikh Rashid bin Saeed - the largest and tallest spanning arch bridge in the world! From his point of view, architecture and "green" building goes hand in hand with urban design. But there is no single sustainable solution: a construction must be related to the local climate, people and culture.

Hidden away in the hinterland of the Var coastline (France), the villa Navarra, practically boils down to its roof: an immense visor stretching 40 metres with a cantilevered surface of 7.80 metres. An exceptional work, both aesthetically and for its technical complexity, this ultra-thin roof made of Ductal® concrete is a world first. Rudy Ricciotti, laureate of the 2006 National Architecture Grand Prix, Romain Ricciotti, structural engineer, and Mouloud Behloul, Lafarge concrete engineer, present the building.

Born in Canada in 1929, Frank Gehry won in 1989 the famous Pritzker Prize for lifetime achievement, but Gehry had only just begun. The most significant achievements in Frank Gehry's prolific career include LA's Disney concert hall, U.S.A., and of course the Guggenheim museum in Bilbao, Spain. Actually Gehry certainly knows how to use industrial materials in surprisingly poetic ways. Only materials remained as a way to humanise a building: this has become his trademark...

Frédéric Borel sees the role of an architect as carrying out work that no computer can do as each project is a forward-looking personal interpretation requiring a highly global approach. He is the architect of the new École nationale supérieure d'architecture de Paris-Val de Seine (National School of Architecture), France, a new building in a former factory.

"With the arrival of ultra-high performance fiber-reinforced concrete, we are moving into a new industrial era. Architects are like test pilots on the runway, ready to take off... and we're trading our propeller engines for jets! The Peace Bridge in Seoul spans 130 m but its deck is only 3 cm thick! The concrete slims down until it becomes no more than a delicate whisper."

"The architecture of the 21st century will be environmental or it will be nothing! We must work to minimize the overall impact of buildings on the environment."

"I chose concrete because I wanted to restore and embellish its good name. This material is very widespread is seldom accepted by inhabitants. Unlike smooth, architectonic concrete, the surface treatment I have chosen evokes the haphazard poetry of gathered materials used to build the fishermen's huts that characterize this region. The choice of materials is, for me, part of the architectural research, an important element during my reflections on the construction, framework and covering of the building. Consequently, the concrete used for the gymnasium goes well beyond its role as a construction material and becomes the building's skin."

"In this center, visitors are confronted with unusual spaces: the floors are not built one above the other and the blocks rest on cones, which may rise through them. In addition to these architectural aspects, the building is currently the biggest construction in Europe built using self-compacting concrete. Without this new type of concrete, the building's shapes, fretwork angles, curves, interrupted planes and outcroppings would have been more difficult to produce."

"This building rises out of the concrete surface of the bus parking area like an organic outcrop. By striking a chord between the structural characteristics of ultra-high performance fiber-reinforced concrete and its malleable qualities, Ductal® has achieved the ever challenging feat of blending the building and its foundation into a coherent unit."
