forty five degrees is a 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 more-than-human knowledge.
At forty five degrees, our work investigates the built environment through research, design, and artistic experimentation across scales, examining its physical, social, and economic entanglements. Our work embraces collective approaches and alternative models of living and city-making, aiming to develop new spatial paradigms. Through a careful use of scale, material, and design language, we strive to create inclusive and accessible spaces. As architects, researchers, and educators, we operate through an interdisciplinary lens and approach architecture as a multimedia, curatorial, and world-making practice grounded in immersive research, embodied rituals, and publishing as a critical tool.
By diving into the field of expanded architecture, we practice it while collaborating with cultural institutions and creative agencies in Germany and abroad. Our projects have been supported by international institutions such as the Allianz Foundation, Goethe-Institut, PERSPEKTIVE – Fund for Contemporary Art and Architecture, and Akademie Schloss Solitude. We have also worked with KW Institute for Contemporary Art, the European Commission’s S+T+ARTS program, Floating University, and a Horizon Europe research project, among others.
In 2023, forty five degrees were recognized among ArchDaily’s Best Practices and received the Inspire Future Generations Award from the Thornton Education Trust in London. In 2024, the team won first prize in the IBA’27 competition for Neues Wohnen für Korber Höhe in Stuttgart, in collaboration with fatkoehl architects and atelier le balto. In 2026, the studio has been commissioned by the City of Braunschweig to design the urban development of the Am Lehmanger Zobel site, in collaboration with fatkoehl architects.
Alkistis Thomidou, Berta Gutiérrez, and Giulia Domeniconi are founding members of the studio. Since 2023, Alkistis and Berta have been the core team, which takes on different configurations to adapt to each project’s scope and forms multidisciplinary collaborations with other experts worldwide. forty five degrees operates as a GbR, a partnership under the German Civil Code.
