Zurich’s Kongresshaus and Tonhalle have a long and chequered history. Now, after a four-year construction period and many years of disputes about their future, they were reopened at the beginning of September 2021. The result is convincing in its respect for the high quality of the existing building.

The contractor Senn wants to realise the sustainable office building Hortus with her building technicians, with the architects from Herzog & de Meuron and the engineers from ZPF. With its consistently bio-based construction alone, the building in Allschwil should save almost 90 percent CO2 in the shell. Hochparterre magazine is accompanying the planning and construction process.

You almost wouldn’t believe it, but summer is slowly coming to an end. September heralds autumn and some hope it will bring a few more sunny days. Be it on weekends or during the autumn holidays – with these five new Swiss attractions, planning becomes a breeze.
