Founded in 2000, 2/3/4/ unites the experience of three French firms that, since the early 1980s, have paid particular attention to new lifestyles that demand a return to simplicity and the basics. 2/3/4/ defends the luxury of a "lifestyle" that seeks out "well-being". Made to measure, each project is the opportunity for a study that makes it unique whether in terms of sustainable development, typology or construction system. Just as the glassblower, 2/3/4/ buildings take their shape from the inside. Like clothes, their envelopes protect without restricting movement. Like a landscape, they change over time. Even before the selection of construction materials, 2/3/4/ favors the only readily available raw material: light. 2/3/4/ believes "density" is the major component of the city. • Their expertise on the permeability of buildings allows such an alchemy to transform "density into intensity". • The luxury that we defend: to give everyone a place • The shape of our buildings is always generated by an internal momentum. • To favor the only readily available raw material: light. • Each project is an opportunity for study that makes it unique
