forty five degrees is a collaborative studio of architects and designers. In our practice, space-making is about resources, not only material or financial but the intangible resources of human and non-human knowledge.

In forty five degrees our work aims at investigating the built environment through research, design, and artistic experimentation, across multiple scales, analysing its physical, social, and economic entanglements. We are interested in gathering protocols and collective approaches, exploring alternative living and city-making models and new paradigms of urban development by engaging with communities and local agents. We strive to create inclusive and accessible spaces through careful use of scale, material, and design language and are committed to rethinking education through academia and practice, placing design at the intersection of arts and sciences.

We work with cultural institutions and creative agencies in Germany and abroad. Together with the Art Mediation department of KW Institute for Contemporary Art in Berlin, we have developed the project ‘3rd Space formations’ and the scenography of the ‘30 years KW summer festival’. forty five degrees was digital research residents at Architectuul and had a 3-month residency at the Eastern European exchange network- supported by Goethe Institute Romania and Akademie Schloss Solitude. Our studio is main partner of the European Erasmus+ Youth in Action project “The Studio” together with Byverkstedet (Oslo) and Premices and co (Paris) and was recently selected for the PERSPEKTIVE- Fund for Contemporary Art and Architecture.

Our team takes different forms when engaging in collaborations with other experts, adapting to each project’s scope. forty five degrees was founded in November 2019, but took its official legal form in January 2021. forty five degrees is GbR, a partnership under the Civil Code.
