This book offers a series of perspectives on tacit knowledge in architecture, hidden between the lines of text, lines of a drawing, and lines manifest in the built environment. The essays encapsulate three years of discussion and collective reflection across architectural practices, cultural and academic institutions. As a whole, they present a kaleidoscopic view of tacit knowledge in architecture as it unfolds from bodies, sites and identities; resides in models, drawings, reflections and senses; and builds new communities of practice.

„TACK / Communities of Tacit Knowledge: Architecture and its Ways of Knowing“ was a funded Innovative Training Network between 2019–2023, as part of the Marie Skłodowska-Curie Actions within the European Framework Program Horizon 2020. It trained young researchers in understanding the specific knowledge that architects use when designing buildings and cities.

TACK gathered ten major academic institutions, three leading cultural architectural institutions as well as nine distinguished architecture design offices. Collaboratively these partners offered an innovative PhD training program on the nature of tacit knowledge in architecture, resulting in ten parallel PhD projects.

The TACK Publishing Platform was conceptualized by Helen Thomas, designed by Lizzie Malcolm with Dan Powers of Rectangle and edited by Korinna Zinovia Weber.

The publication is an outcome of the TACK project that has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 860413.
