The landscaping aims to open up and aerate an existing square, heavily fragmented by hedges and compact vegetation. Green areas are reopened to the public, tree canopies are lifted, and access from the hospital becomes natural and permeable. Toward the boulevard, a layered living wall provides visual screening, while the square's center is organized with perennial plantings that emphasize the main axis and add spatial depth. Selected vegetation includes native or well-adapted species with seasonal interest and low maintenance requirements, while existing trees are preserved and integrated into a coherent, welcoming setting.
