With the Haus des Lebenslangen Lernens (House of Lifelong Learning, HLL), we created a new and pioneering learning environment for Europe in 2008. Bringing together the Max Eyth School, a music school, an adult education center, a high school, and a secondary school for adults, the HLL integrates various educational formats, pathways, and childcare services in an intergenerational learning environment. This exceptional project sees Kreis Offenbach, in the German state of Hessen, fully implementing the educational principles of the European Union’s “Strategy for Lifelong Learning,” adapted by the federal and state governments. The collaborative and integrative profile of the institutions at HLL is reflected in both the architecture and the pedagogical approaches. Close cooperation between institutions, short distances, and the concentration of educational expertise result in significant educational, content-based, and organizational synergies. Facilities and equipment are used throughout the day, reducing costs for specialized equipment in workshop spaces, science rooms, and dining facilities.
