The mortar-free retaining wall system GDM.ALLAN block is now underlining its talent for high-quality open spaces in Berlin-Reinickendorf. The setting is the Dominikus Terraces on a residential complex with semi-detached and terraced houses. The garden, embankment and property walls were constructed in sections as regular or irregular layered masonry. The system's own coping stones round off the atmospheric picture in the color shell limestone.
