hand-drawn semi-intensive roof greening

Quick answer：

Semi-intensive roof greening refers to a type of rooftop gardening where plants are grown in a moderate density, allowing for both greenery and space for maintenance. This method often involves using raised beds, containers, or integrated planters to create a visually appealing and functional green space on roofs. Hand-drawn illustrations of this concept can be used for architectural design, educational purposes, or as artistic representations.
