Details
The hollow concrete block serves as the foundational element for a wall panel, ideally positioned independently in front of the facade as cladding during an energy-efficient building renovation. The unique triangular arrangement of surfaces creates the actual planting openings. The varying inclinations ensure an automatic alignment and easy assembly of the stones. This arrangement also contributes to a dynamic interplay of shadows as daylight changes. Material: fiber-reinforced concrete.
The Jury‘s Statement
The "DreiEcksRautenStein" made of fiber-reinforced concrete is perfect for the stylish and elegant greening of house walls. The striking arrangement of the gray triangular surfaces in combination with the protruding plant opening creates an interesting interplay of light and shadow, which enters into an exciting dialogue with the plants and creates a special impression.
