The Atelier Christian de Portzamparc works on construction projects of all sizes together with a wide variety of construction programs. Each project represents a new challenge requiring extensive research and experimentation, from the initial designs to the search for construction solutions. The Atelier is also an “urban laboratory” that performs in-depth urban and structural analyses, a technique developed by Christian de Portzamparc since the 70’s based on projects “manifestoes“, competitions and studies. This has allowed him to develop his methods and apply theoretical research and analysis principles to a multitude of practical situations. Building on Christian de Portzamparc’s renewed vision of the urban structure, which he calls the “open block”, the Atelier’s work focuses on research, the quality of living spaces and understanding the city. From unique and outstanding buildings to new approaches to urban planning, the town is the building block of his work, developed in parallel and conjunction with three key elements: landmark buildings, towers, and neighbourhoods, from blocks to the development of major cities.
