A three year study from the Swiss, Norwegian and Dutch Institutes on the subject of wood structures and joints across Europe. The aim was to study and develop new approaches to making wooden structures. To focus on the properties, the details and strengths and potentials of wood, not simply its appearance. "Tectonics - the study of joining individual parts together to make up a whole". It is a modernist call for timber, and the details, both those of the past and those emerging from ahead, are coming from multiple directions. A new age of timber, a natural source, a holder of health. Lovely drawings, examples and spirit.
