Girasole is 2021 international competition to developing  Bank for International Settlements(BIS) in Basel into an urbanistically compact and cohesive ensemble consisting of two towers and a low-rise base building. This creates generous public open spaces for the city and BIS. The Second Stage Development adds a third, elongated volume.

Together working between Boltshauser Architekt and manoa landschaft ag, while the base is developed from the existing building and continues its formal language, an approximately 125-meter-high rectangular high-rise follows opposite the SBB station. This presents itself elegantly proportioned as an innovative and sustainable wooden building with a filigree, dynamic photovoltaic façade. Together with advanced concepts for green spaces, energy, water management, building automation, CO2 reduction, daylighting and efficiency, the result is a holistically conceived and expressive new headquarters for the Bank for International Settlements.
