Sub is an architecture practice founded in 2018 by Vanessa Pointet and Thibaut Pierron with projects in Europe. We investigate the specificity of architecture within a world of artefacts and its ability to perform in contact with the environment. In other words, we seek for a kind of “architecture of the well-tempered environment” in the age of ecological transition as much as we look for a sort of “territorial architecture” which measures up to the city-landscape: an architecture of the climatization of the world.
