The stadium which enjoys an area of 9,132 m² will be upgraded to a multifunctional sports facility boasting plush facilities with main impetus on athletics. Once the transfiguration work is over (2023), the arena will be able to accommodate up to 15,000 more spectators. In order to lend the vibrant atmosphere of a stadium in the real sense of the term, the South Stand, the existing North Stand and areas of the East and West curve will be brought together in a uniform overall shape by a spanning band. The construction of a fencing hall, multifunctional sports, fitness and conference rooms, space for sports medicine, offices and clubs as well as catering are also being planned as part of the revamp work. Hosting all kinds of sports under one roof best serves the purpose which would be in the case of the reconfigured Heinz-Steyer-Stadion. The various spaces of the arena would be positioned in such a manner so that they correspond to the usage-specific requirements. For example, the rooms will be built in such a way so that enough daylight comes in. In the same way, the sales areas should be easily accessible to the visitors. A new plaza will also be built between the ball sports arena and the Heinz-Steyer-Stadion as the central entrance to the Ostra Sports Park. This space will be used for holding sporting fixtures or other events. In addition to the new construction of the South Stand, the planning and construction of the outdoor facilities (stadium interior including floodlights and scoreboard), the stadium forecourt and multifunctional area, the expansion of the spectator curves as well as the traffic and media development are part of the planning and construction services.
