First-floor下沉式庭院floor plan

Quick answer：

A first-floor sinking courtyard floor plan typically refers to a layout of a building's ground floor that includes a sunken garden or courtyard. This type of design is often used to create a private outdoor space that is partially or entirely below ground level, providing a sheltered and secluded area within the urban environment. The plan would detail the dimensions, layout, and architectural features of the courtyard, such as garden beds, pathways, and structural elements like walls or pergolas. Such designs can enhance the aesthetic and functional aspects of a building, integrating nature into urban living spaces.
