Text description provided by the architects. Due to the location in the city of Linz and restrictions on the premise boundaries, the voestalpine steel company needs to pursue alternative growth strategies. An important method of achieving this is through the strategic concentration of facilities and processes on the premises. For this reason the idea developed to concentrate the existing scattered parking spaces, which use up a lot of space, to a centrally located car park. Strategically positioning the car park has proved to be a prototypical solution when considering transformational processes of industrial premises that have limited possibilities for geographic extension.
Regarding the steel manufacturer’s specific request, we succeeded conceptually and constructively in highlighting the processing of metal within its own factory buildings. In reference to the core competence of the voestalpine to manufacture and process steel plates, trapezoidal sheet metal with a series of bends forms the outer façade. Bent sheet metal forms the porch of the bus station on the ground floor. The supporting framework of the five storey car park, consisting of undisguised steel beams and uprights, is remarkable as it is a steel construction which was developed by means of fire simulations and offers slender proportions as well as cheaper building costs.
A central aspect of the parking level and the vertical elements is to give the car park users a feeling of safety and for them to be able to intuitively orientate themselves. While the sunlight is caught in the delicate layer of steel ropes during the day and the sheet metal’s multi-coloured coating shines, the reflections from the floors coated with epoxy resin transform the parking levels at dusk to an interior shining from within.
Each level consists of an access and exit ramp as well as three lifts, one of which leads directly to the bus station. The surrounding office buildings can be directly connected to the upper levels of the car park via foot bridges. The daily route of drivers from car to workplace becomes shorter and more convenient and an optimal vertical distribution of the car park’s usage is therefore encouraged.
The company’s rail system still runs diagonally below the five square parking levels which are 65 metres in length and 19 metres in overall height. This building therefore combines an existing rail track and a car park for 800 vehicles which will serve as a traffic hub and hence enables the steel company voestalpine to use its limited internal surface area in an optimal way.
