Dado Furniture Uses Single Joint for Tool-Free Assembly
Berlin-based studio reimagines ancient woodworking techniques for modern, sustainable flat-pack furniture design.
1Innovative Woodworking Technique
Berlin studio Allen Kaufmann Architekten has developed a furniture range that requires zero tools, glue, or screws for assembly. The collection, known as Dado, relies entirely on a reimagined traditional housing joint. This ancient technique, typically used for simple grooves, now serves as the primary structural system for tables and shelving units.
2Geometry as Structural Support
Co-founder Justin Allen spent years prototyping a patented joint that functions at a 45-degree angle. This specific geometry allows four distinct wooden elements—vertical, horizontal, and two diagonal braces—to lock together at a single point. The resulting structure mimics timber barn construction while maintaining a distinct, modern aesthetic for the furniture.
3Sustainable Flat-Pack Logistics
The system addresses common industry issues regarding cumbersome, permanent fixings that increase transport emissions and costs. By avoiding screws and brackets, the furniture becomes easily demountable and repairable. This design choice prevents the abandonment of functional pieces, as components can be disassembled, transported, and reassembled repeatedly without damaging the integrity of the wood.
4Exposed Design Philosophy
Allen intentionally leaves the joints exposed so owners can clearly understand the assembly mechanism. By making the connection visible, the joint serves as both the structural backbone and the primary decorative detail. This transparency encourages users to maintain their furniture, fostering a deeper connection between the object and its long-term functional lifecycle.
5Precision Manufacturing Process
Each standard component within the Dado range is produced using CNC milling for high machine precision. This manufacturing approach allows the furniture to be produced by local workshops anywhere in the world. By enabling decentralized production, the studio significantly reduces the environmental impact associated with shipping heavy, pre-assembled furniture across global markets.
6Industry Recognition and Awards
The Dado range recently received the furniture design of the year title in the Dezeen Awards public vote. This recognition highlights the project's impact on contemporary design discourse. The studio is now competing for the overall winner title against established international designers, including projects by Tom Fereday and Yabu Pushelberg.
7Expert Jury Evaluation
The final selection for the overall winner will be determined by a jury of prominent industry figures. Notable names on the panel include architect Norman Foster, designer Michael Anastassiades, and Jaime Hayon. Their assessment will weigh the project's technical innovation against other high-profile entries from global design firms and established furniture brands.
8Future of Modular Furniture
The success of Dado signals a shift toward more repairable and modular consumer goods. By proving that complex structures can be achieved through simple, geometry-based joinery, Allen Kaufmann Architekten offers a blueprint for future designers. This approach prioritizes material efficiency and user autonomy, challenging the reliance on disposable, hardware-heavy flat-pack furniture systems.
