Applications of concrete are so common, while possibilities to shape -so unusual that it's hard to imagine a civilization in its present form, without its participation. It seems to be particularly invaluable in infrastructure projects. However, recently, in these applications, where it is directly exposed and interacts with the landscape, visual perception of concrete is changing and it is now increasingly being considered as a material brutal and uncouth in its technological sincerity.Opportunity to work out a new paradigm of practice for designing sustainable infrastructure is offered by technology based on biological methods. The process of artificial biocalcification of sand through ureolysis, otherwise called biocementation can be performed with use of some microorganisms such as, for example Sporosarcina pasteurii (former Bacillus pasteurii). Its result is reminiscent of natural sandstone rock. Very interesting opportunities open up for designers in shaping the spatial forms using this technology. In a natural way, it is possible to obtain structures resembling naturally occurring rocks, called tafoni. Their complex geometry causes that their construction of concrete by means of traditionally used techniques, would be either impossible or very expensive. It is also possible to apply biological cementation for surface hardening of large areas, e.g. the surface of the shifting sand dunes, to protect against movement. Inherent advantages associated with the concrete, combined with material formed in a biological process for forming complex spatial forms can be a significant factor in the humanization of the inhabited environment.

The work of Stéphane Du Chateau is clearly inscribed in the second half of the twentieth-century. Throughout his life, the famous engineer and architect developed and patented several spatial structure systems based on an ingenious design of nodes and skillfully applied them in the architectural form of various buildings. As of today, over 250 of his designs were successfully realized. Apart from the above, Stéphane du Chateau also established several associations in order to bring architects together and to promote Spatial Structures. His charisma and commitment brought a remarkable contribution to spatial structures.
