What is it that makes up a contemporary model of architectural and constructive action? The offsite model. The industrialized, prefabricated, modular, offsite construction allows us to distinguish a work of architecture from the second millennium, from the 21st century. Will it be the materials, will it be the forms, will it be its functionalities, will it be the ways of working with its users … what will define the use of data and its transformation into something constructed? A new range of agents and suppliers appears before us and the need to identify them and combine a common position has led to the creation by this ecosystem of a common space, a hub. The Offsite Construction Hub will try to “lobby” the architecture of the future and of the present that will allocate their work patterns towards Construction 4.0.
