Those who think sustainably can act sustainably. hartmannvonsiebenthal implements sustainable action in the Alnatura store in Potsdam, down to the last detail: natural and recycled materials, terracotta floor tiles, shelves made of Bavarian spruce wood, appropriate air supply, and energy-saving lighting make visitors experience sustainability directly in the store. A terrace, with urban gardening elements, children’s play area and bike racks, invites customers to take their time for the important things in life.
