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. The office was founded in 1985 in Tübingen by Prof. Gerd Ackermann and Prof. Hellmut Raff. In 2010, Alexander Lange, Oliver Braun and Walter Fritz joined the management team as partners and managing directors, followed by Florian Gruner in 2021. Today, the office employs around 130 dedicated staff at its Stuttgart and Tübingen offices and is headed by Oliver Braun, Florian Gruner and Alexander Lange. 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. In line with the conviction that “only together as a team can we meet the challenges of the future,” a+r Generalplaner GmbH was founded in 2021.
