Studio PART is a design duo from Antwerp. Interior architects and furniture designers Julie Van Mulders and Lennart Van Uffelen have been working together since 2020 and are known for their sparing use of materials and their research into innovative manufacturing processes and materials. Both are interior design professors at LUCA School of Arts, in Brussels. Their collaboration with ETAP and Circular Matters won them a bronze medal at the Henry van de Velde Award in 2023 in the environment category.

Having a technical background, Julie Van Mulders and Lennart Van Uffelen express their love for craftsmanship. The duo makes its own prototyping and crafts made-to-measure pieces from different types of material, mainly wood and steel.

They do extensive research and try to define what makes a material its own and which craftsmanship is necessary to make a collection from it. Their 2024 research includes the willow tree chair prototype and the use of a new material made of corn developed by Circular Matter. The name PART itself refers to the fact that they consider themselves as being part of a design process as well as part of the environment.
