The planting strips will be divided into bed segments with paved walkways and bordered by a raised granite plinth topped with a raised border grid. An automatic irrigation system with drip hoses will be installed. The existing benches will be replaced with new ones. These new benches were designed specifically for the Unter den Linden location and will be provided by the client. The existing light poles will be removed by Stromnetz Berlin and reinstalled by them after the substrate has been installed. Some light poles will be relocated to a new position.

Following the initial maintenance period of up to one year, a three-year maintenance period will be required. The project will be implemented in five phases, defined by the traffic junctions.
