As well as working on industrial design projects with his office, Patrick Jouin ID, he also works on interior design projects through Jouin Manku, founded in 2006 with his colleague Sanjit Manku. For the two, there is no distinction between architecture and design. Every question regarding to space and its relationship with people - on every scale - is an opportunity to express unity of design.
Jouin has developed furniture for some of the best-known companies in the sector. His longest-standing collaborations include Porada, whose most recent products include the Leaf coffee tables, and Pedrali, for whom he designed several successful series of upholstered furniture, including the sinuous Ila armchair collection. For Cassina, he created a family of products (table, chairs, sofa, complements) that debuted at the Cologne Furniture Fair in 2003. He collaborates with Kartell, Alessi, Puiforcat, JC Decaux, Fermob, Pedrali, Busnelli. For FIAM, he designed the Aura curved glass display case and the Magma glass table.
