DiDD Deventer Interior Design Days 2026

DiDD Deventer Interior Design Days is an interior-design event organized by Saxion University of Applied Sciences’ Interior Design and Interior Brand Identity programs, held annually across five days in central Deventer in the Netherlands. It runs each year in late September or early October, spreading exhibitions and activities across multiple locations in the city center.

The program centers on a yearly theme, with the 2026 edition built around MUTE, examining interior design as an ongoing movement rather than a fixed outcome. Visitors can see graduate and student work alongside professional designers’ projects, plus talks, installations, workshops, masterclasses and career-focused sessions for those considering the field. Because it originates from an educational program, DiDD gives particular visibility to emerging design talent, positioning itself as a showcase for the next generation of interior designers as much as a public design event.
