Korkeasaari Zoo (Helsinki) and Wood Focus Finland organised an architectural competition for the students of architecture at Helsinki University of Technology, with the assignment of designing a ten-metre-high view tower out of timber for the Zoo.The free form was motivated by the natural setting; it follows the surrounding stone wall and skirts around a group of birches.After the workshop, the architect laminated full-scale test pieces of battens, which form the basket-like gridshell. He studied whether the pre-bent battens tolerate bending and twisting to a sufficient degree as to allow their use in a construction of this type. When the laminated timber resisted twisting he resorted to steaming, a traditional method in boatbuilding. The effect of surface treatment with linen oil-based wood balm on moisture content was determined by moisture tests and the durability of the joints was proved by tension tests.Finally in June-August 2002 the tower was erected by an international group of eight students of architecture. The structure behaves like an eggshell; even when the gridshell, which consists of over 600 joints, is punctured it withstands the load. The load bearing structure consists of 72 long battens with a section of 60mmx60mm that are bent and twisted on the site from seven pre-bent types. As the tower has no structural protection against weathering, it is treated with a linen oil-based wood balm with UV-protection.
