De Haan Group is an expert when it comes to fitting garden centres. At the entrance of this completely new building of their own design, one is easily awed by the large street-art portrait of Einstein with tousled hair made up of artificial leaves. Living green is integrated throughout the building. Even a live tree is allowed to grow between the desks. Thanks to the 1680 solar panels on the roof, the building is carbon neutral, which means excess energy is delivered to bulk consumers in the region. The grass around the building is trimmed by two sheep.
