Atelier D is a Paris based agency specialised in Sustainable Architecture, born in 2003 and leaded by a cosmopolitan team of 3 associates: Mattias Piani (italian), Vanessa Grob (chilean) and Ilhem Belhatem (algerian). Atelier D’s original and resolutely modern works make them one of the most innovating sustainable architecture agency today in France. Atelier D’s projects are regularly noticed, awarded or published and the associates are used to organise conferences with institutions and professionals in the fields of architecture, industry or sustainable development, where they explain the results of their researches.
