About us

Dedicated to Architecture

Introducing ArchiTangle

ArchiTangle is a Berlin-based independent publishing house and digital service provider in the architectural space, focusing on knowledge transfer and projects of social relevance. Founded in 2019, ArchiTangle’s publishing program spans the entire architecture spectrum and aims to preserve the exchange of architectural knowledge through publications and archiving.

More than Books
ArchiTangle’s novel blockchain-based archiving platform enables architects to securely store sensitive documents without any intermediaries. Architects hold exclusive control over their data stored on the platform – no third party can ever gain access without the originator’s permission.

Vision

"Everything that we build, we build for human beings."

- Balkrishna Doshi, 2019

At ArchiTangle, we believe in the power of books and their impact on education. Everything we do relates to our goal of strengthening and attracting a younger audience through our knowledge-transfer platform for architectural research. In line with the United Nations Sustainable Development Goals (SDGs), we partner with leading architects and artists to promote open access to scientific book content for students and academic institutions worldwide. Our mission fuels us as a team, to support and facilitate research in the architecture space.
