A 400-meter-long roofed connecting passage crossing the botanical garden „Planten un Blomen“, leads from the Convention Center to the Trade Fair Exhibition Halls. A fan of glass roofs hover above gently undulating, breached walls. The careful combination of diverse materials betrays a leaning towards the art of detail. Caterpillar-like, the glass walkway „moves“ through the terrain. Massive wall pillars carry a filigree roof construction covered with glass, wood and steel.
