The logs utilised in Hämeenlinna originate from a house built in the late 19th century on the Onali estate in Hartola. Initially a modest cottage, it later expanded, eventually becoming a 300 ㎡ mansion. Logs used in the construction of old buildings were typically made of various trees – for our Hämeenlinna project we sawed them, sanded them, oiled them and modified steel legs to suit the logs.
