PROBLEM TO BE SOLVED: To provide a fire spread-preventive construction for a greening structure preventing fire spread over a greening structure set up on its roof or rooftop. SOLUTION: The fire spread-preventive construction for a greening structure is structured so that the planting layers B of greening structures A1, A2 are each partitioned into a plurality of areas with partition wall members 20, 30, 40. By such a structure, when the fire begins to burn the planting layer B in a certain area, the fire spreading via the planting layer B is blocked by the partition wall members 20, 30, 40 to prevent the fire from getting to the planting layers B in other areas.
