Tectonics and architectonic quality in recently published Finnish log architecture: Corresponding architects’ perceptions

Due to the global increase in wood construction, it is crucial for architects to understand wood. In Finland, log building, a special subset of industrially manufactured massive timber construction materials is experiencing a renaissance. Cultural aspects combined with newer technical developments make log a complex material from the viewpoint of architectonic expression. To inform practicing architects, the aim of this study is to explore how the tectonics of logs contribute to the architectonic quality of log architecture. Semi-structured interviews among architects of twelve recently published log buildings are conducted. The results describe how architectonic quality is perceived among participants, and features of logs related to tectonics that they consider to be of importance in terms of architectonic quality. These features include the statics of log construction and log's nature as a simultaneously insulating, load-bearing and visual material. Differences between industrial and hand-hewn logs, as well as other architectural aspects of using logs in contemporary architecture are discussed. Especially the “non-settling” log was perceived to have manifold implications for the architectonic possibilities of log architecture. The results are of practical importance to designing architects and the log industry. Theoretical implications include tangible information on architectonic quality and tectonics of log building.
