—  Covering a wide range of industries, for companies big and small

In 2004 Silvia Beretta and Stefan Kastner founded their landscape architecture practice in Italy, bringing together different cultural backgrounds and a cross disciplinary approach on landscape design. In 2014 they moved to Germany opening in Aachen beretta kastner landschaft architektur.

The office carried out several prestigious private gardens and high quality landscape architecture projects, both for private companies and public administrations across Italy and Germany, earning prizes in international competitions.

Since 2017 Stefan Kastner is partner of 3PLUS FREIRAUMPLANER, a landscape architecture practice based in Aachen with several years of experience.
