«Villeverte»
With similar widths and spacing, but with staggered heights, four slender high-rises – in contrast to the horizontal structure of the motorway bridge – write an attractive skyline into the sky. The offsets of the skyscrapers in a north-south direction create empty spaces and enable views through and across. The urban high-rise ensemble is surrounded by a dense and diverse natural environment.

The central high-rise stands centrally on the new neighbourhood square and is conceived as a vertical overlapping of uses with intermixed neighbourhoods. The Viaduktforum with its hall, grandstand and bistro, studios, creative industries and cultural scene are nestled in the base. The upper floors house a cooperative with a variety of subsidised or self-supporting flats, with collective, semi-public uses on a mezzanine floor with a terrace.

An efficient column-and-plate system with continuous load transfer supports the 97-metre high-rise. An energy network, green plinth sections, prefabricated timber façades and a photovoltaic envelope coordinated with the neighbours fulfil the promising sustainability goals of the high-rise ensemble.
