Highly commended: Mixed-use project of the year 2024. Ingenhoven Associates has reconstructed and redesigned Calwer Passage in Stuttgart, Germany.

Nestled in the heart of Stuttgart's city centre, the reconstructed Calwer Passage introduces lush greenery into the cityscape while preserving heritage-listed building sections.

The greening of facades and rooftops establishes a high-quality urban space with a natural, healthy climate, while the rich diversity of species generates a vibrant and ever-changing appearance.

Architecturally distinctive, this pioneering project embodies an ambitious fusion of construction, technology and nature.

Calwer Passage effectively contributes to a greener, more humane, and resilient urban landscape, thereby markedly elevating its allure and sustainability.

Judges comments: "This project is an innovative example of how an existing building can be adapted to create a healthier and more appealing environment for both its occupants and those that pass by."
