The design concept aims to adhere to the principles of the original architectural concept, while giving the existing building composition a visually orderly structure by sensitively modulating its façade surfaces. The uniform height of the five office towers now creates a rhythmic spatial sequence, giving the visible street frontage a striking contour in terms of length, depth, and height. The design and aesthetic qualities of the building, which has been extended by two lightweight floors, are evident in the sensitively realised depth effect of the façades.
Redensification is one of the architectural topics that will continue to preoccupy us in the future.This applies not only to residential and commercial buildings in rural areas, but also to Graz University of Technology's inner-city grounds. It houses the Mechanical Engineering Institutes. The aim of this project is to counteract the 'fragmentation' caused by small-scale additions and extensions. The aims to ensure that future space requirements can be met in the long term. Raising the office towers to the height of the four upper floors will create the necessary expansion space for the institute's operations. With their irregular cube shapes and unequal heights, the buildings form the internal area of the institute. They divide the outdoor space into various open areas and usage zones.
The precisely executed aluminium façade reflects the content and function of the buildings housing the mechanical engineering institutes. A notable feature of the façade is the trapezoidal sun protection structure positioned above the window band and intersecting with the opposing panel structure below the window sill. This interlocking creates a striking design feature that emphasises the façade's significance and sophistication.
The topic of sustainability is evident in several aspects of this project. The existing building was not demolished and replaced The necessary usable space was created within the five towers. This avoided the need for further sealing. A lightweight wooden structure was used to add extra storeys At the same time, the thermal situation was significantly improved. - The curtain wall façade prevented cold bridging between the existing building and the extension. - The coated sheet metal façade is sustainable and can be dismantled and reused. It also guarantees low maintenance costs. -The clear structure of the existing building and the five towers has resulted in the urban redevelopment of the heterogeneous environment. The project won the Domigius Architecture Prize and the Best Architect 25 award.
This renovation and extension building from the 1970s faces the task of responsibly using the existing building substance for the structural and functional requirements of today and tomorrow. The building, which has been extended by two light-weight storeys, only reveals its aesthetic design qualities at second glance, which is due to the sensitively realised depth effect of the façades. The almost joint-free rectangles of the snow-white parapet façades are covered - even more discreetly - by the shadows of wedge-shaped translucent shading elements, which generate plays of light and shadow from the horizontal to the vertical. The material contrast between the exposed concrete and the new façade - separated by a clear vertical building joint - intensifies the compositional effect. Overall, the jury praises a work that is captivating in its simplicity and tranquillity.
