- Sportshall structure
Conceptual design for a sporthall located in Poznan (Poland).
- The sportshall is located on the northern part of the Poznan Cathedral Island. Cathedral Island is an island between two branches of the river Warta in the city of Poznan in western Poland. Poznań Cathedral and other ecclesiastical buildings occupy the central part of the island. Ostrów Tumski is part of the city's former New Town district, although it is actually the oldest part of the city, where the rulers of the early Polish state in the 10th century had one of their palaces. The design site is an open area and it does not contain any significant dominant or important architectural context.
The main architectural topic is to design a sports hall on the open area which in the future become the cultural centre of Poznan. The main challenge is to design an attractive form while highlighting the landscape qualities of the proposed site. The structure of the building is a single aisle hall, with auxiliary facilities located along outside of the building block. Visitors access to the hall is via the air bridges. There is also a separate entrance for athletes. The outer structure of the hall by its form recalls the structure of human bone. This bone is to a great extent less dense and more porous comparing the compact or cortical bone. This is made up of trabeculae or a spongy latticework. This is found mostly in the epiphysis regions of the long bone and also in the central segment of the most bones of the body. Filling the interior of the bone is the trabecular bone tissue (an open cell porous network also called cancellous or spongy bone), which is composed of a network of rod- and plate-like elements that make the overall organ lighter and allow room for blood vessels and marrow. Trabecular bone accounts for the remaining 20% of total bone mass but has nearly ten times the surface area of compact bone. Its porosity is 30–90%. As a result, the sports hall area is a porous structure. In order to adapt this idea to the functional conditions surface porosity varies along the enclosure. The structure is more dense on the top and the cells are enlarged where main entrances are located.
