Roof-top open-air garden image

Quick answer：

Roof-top open-air gardens are spaces designed on the roof of a building, typically featuring greenery and plants. They can be used for relaxation, recreational activities, or as an extension of the living space. These gardens are often found in urban areas where green spaces are limited. The image you're referring to would likely show a view or layout of such a garden, complete with vegetation, seating areas, and possibly decorative elements.
