eins:eins Architekten BDA is an architectural partnership founded in 2006 by Julian Hillenkamp and Christoph Roselius in Hamburg. The firm has established a reputation in the region as one of the more prolific offices in architectural competitions, consistently working from their address at Eimsbütteler Chaussee 37. Their team undertakes the full range of architectural services, starting from early concept and design stages through to project planning and site supervision, emphasizing ongoing involvement from initial idea to completed building.
eins:eins maintains a portfolio characterized by a focus on public and community-oriented projects. Among their notable works is the Centre for Speech and Movement (Sprach und Bewegungszentrum) in Hamburg, completed in 2013 as part of the International Building Exhibition. This facility employs spatial design to facilitate language acquisition through movement, with a distinctive interplay of old brickwork and contemporary detailing. Another project, the KITA Bergstedt daycare center, earned the office the BDA Hamburg Public Architecture Award in 2018.
The practice’s approach is rooted in balancing client needs and architectural vision, seeking clarity in the transition from design to built reality. The name “eins:eins” itself, referencing a 1:1 scale, illustrates the firm's emphasis on precise execution and the intent to closely align planning with the end result. eins:eins Architekten BDA is a member of the Association of German Architects (BDA), reflecting its engagement with the standards and discourse of the profession in Germany.
