In the summer of 2015, the Walker announced a plan to unify the Walker and the surrounding Minneapolis Sculpture Garden. Key features of the renovation include a new entry pavilion for the Walker, a new hillside green space, the Upper Garden, and the reconstruction of the 26-year-old Minneapolis Sculpture Garden, a partnership with the Minneapolis Park and Recreation Board. The project also implements green-roof technology, rainwater reclamation systems in the Garden, and the addition of hundreds of new trees throughout the campus.
