‘Apelle’ is a wooden family home located in Karjaa, Finland, designed by Marco Casagrande. The building rests in a natural harbor like a boat in a sheltering pocket surrounded by bed rocks and trees. The interior space of Apelle is a continuous tube that grows gradually along the house and through the main opening and terrace into the forest. Along this axis the collective and private actions are tuned according to the times, functions and needs of the day and night. Through this the architecture is part of nature. The surrounding forest has been architecturally articulated into a shelter for a family of contemporary natives. The house is in the forest as much as the forest is in the house – the architecture is a mediator between the modern man and nature.
