a+r Architekten stand for solid, environmentally compatible and future-oriented architecture with impressive expertise in the field of sustainable building — also in existing building contexts. Founded in 1985 by Professor Gerd Ackermann and Professor Hellmut Raff, the office with branches in Stuttgart and Tübingen has around 100 employees and is today headed by Oliver Braun, Florian Gruner, Alexander Lange and Walter Fritz. a+r Architekten mainly build for public clients, industry and commerce, municipal housing companies and social institutions. The office focuses on appropriate, ecological, functional and the resulting innovative construction methods and has been awarded prestigious prizes for this approach: most recently, best architects 22, DAM Prize 2020, Exemplary Construction Award 2020 by the Baden-Württemberg Chamber of Architects, “best architects 2020” and first place in the Competitionline Ranking 2019/20 as the most successful competition office in German-speaking countries.
