This building has won the contest as the natural building. This building is designed based on the concept of a prototype wooden construction system for a pilot project. This building is created with the friendly natural materials so it will be friendly to the nature but safe to life. To meet the increasingly stringent environmental requirements of Finnish industrialized construction, the E2 Ecology & Economy timber development competition aims to find a conceptual design solution for large-scale production of wooden multi-story buildings. Since this building is made mostly from the timber, this building is very comfortable to live like back to the nature. Wood as construction material brings a double benefit: remarkably reduced emissions in its production and fabrication and improved energy efficiency of the buildings where it is used. The wood also gives artistic feeling and classic value but the quality is the best. It can be very long lasting. This is completed with safe electricity system and has fire extinguishers. This building also has good yard and environment.
