Muscular Modern Minimalism
Led by Matthew Bietz, Quartertwenty® designs and builds projects at a variety of scales including furniture, installations and buildings, exploring relationships between design, art and production.
Matthew Bietz gained fluency in furniture and metalwork while receiving a Master’s degree in architecture at the University of Washington. He supplemented his architectural education with real world experience at Gulassa & Co., a Seattle based custom fabrication studio, where he worked on a wide range of projects that included the work of Steven Holl and Tom Kundig. His hands on experience in design and construction was further influenced by a design‐build project that he completed with Jersey Devil founder Steve Badanes in Mexico. He bookended his architecture degree with a Valle Scholarship, studying the museums of architect Sverre Fehn throughout Norway for 6 months. Bietz worked for several years in the construction industry before launching Quartertwenty in 2007.
