Three + One is a minimalist furniture series created by Berlin-based designer Lukas Wegwerth. Three + One is a system which applies modular and structuralist design principles to 4.0 production methods in order to build furniture and architectural-scale structures for social spaces. With a minimal joint, a scalable, plug-in connector, THREE+ONE holds convertibility and a straightforward construction approach as its core values. It provides a platform for collaborative building, lending itself to use in multiple contexts such as exhibition design, academic research, public spaces and private interior.
