Geologist Helle Perens emphasises that instead of worrying about the environmental impact of quarrying building stone, we should worry that there are plans for the near future to extract senseless amounts of it, including very high-quality stone, only to crush it into aggregate.
Architect Madli Kaljuste takes a look at Linnahall that hides traces of 400-million-years-old life in its walls.
The essay ‘Sedimentary Flows and Creative Geologies’ by Galaad Van Daele was commissioned for the publication Reset Materials–Towards Sustainable Architecture, edited by Chrissie Muhr and published by the Danish Architectural Press (Arkitektens Forlag, September 2023).
Air and its composition concern every field of spatial design, both at the micro and macro levels. The way in which airflows are controlled reveals how a built space relates to its surrounding environment. Hence, in this issue we ask: how does your house breathe?
Humankind is transforming the planet into a vast infrastructural project serving its economic system. Landscape architect Hannes Aava explores how this development is reflected in critical theory and discusses what must be done to prevent the metabolism of humankind from becoming a metastasis.
All new hard infrastructure should be engineered to double as social infrastructure, writes Mattias Malk.
Ingrid Ruudi discusses architects’ relationship with time and the various ways in which architects in their later years record their doings as history.
When a certain building technology or material is sidelined for an extended period, one is bound to get the impression that it is intrinsically obsolete.

What is happening in the freshly insulated walls of author’s home?
