François Chas, Nicolas Guérin, Fabrice Long, and Paul Maitre Devallon are architects of Cartesian method: their projects stem from a deduction process grounded on the drawing, “the first act of building,” which helps them take on the complexities of the context and turn them into works of great clarity and boldness. Operating from Paris and Nice, in this long course au soleil which began in 2009 the practice has like the sage from Touraine worked on the most varied themes, among which a special interest in sports spaces stands out. And between machine-bodies and passions of the soul, between the neutral and phenomenological, their restrained but intense gestures come into play.[+]
