Design a modern high-rise tower in Chengdu that embodies 'Harmonious Elegance.' The structure should blend sleek, contemporary lines with traditional Chinese architectural elements, using natural materials like wood and stone alongside glass and steel. Incorporate soft curves inspired by nature, balanced with geometric precision, to reflect the concept of harmony. The building should evoke a sense of tranquility, with garden spaces, water features, and terraces that integrate seamlessly into the urban landscape, honoring both the past and the future of Chengdu
