Roof-top planting pools are innovative urban gardening solutions that utilize the space on rooftops for cultivating plants. They are designed to provide greenery, improve air quality, and offer recreational spaces in urban environments. Common types of roof-top planting pools include container gardens, raised beds, and green roofs. These cases often involve the integration of sustainable design principles, such as water conservation and soil management techniques, to ensure the viability of the plants in an urban setting.
