The Gäste- und Tagungshaus sits on an idyllic Berlin-Zehlendorf property with park-like grounds offering restful breaks during meetings. The Van-Delden-Haus provides four modern conference and seminar rooms equipped with contemporary technology. The Heimathaus offers a large, light-filled seminar space in its upper floor that can be divided for group work. Together the two buildings provide 42 rooms, including double, single, and wheelchair-accessible rooms. The 1928 Heimathaus was comprehensively renovated in 2014 with individually designed colour schemes. The Van-Delden-Haus, the oldest building, retains its historic character while being modernised with current technical standards. Staff manage all aspects of events: audio-visual equipment, refreshments, meals, buffets and guest accommodation.
