The renovation of the rooftop intends to create a trendy outdoor community hub, as meeting point and leisure space with privileged views over the Xiang River, for youngsters and families visiting the commercial building in Kaifu District.

Taking advantage of the arched shape of the rooftop, the project is driven by the idea of using programmatic parallel stripes of color that would enhance that arched shape forming a rainbow of outdoor. Each of the stripes represented in a different color, is a platform hosting specific functions and features that encourage social interactions through leisure and play. Those programmatic stripes initially executed as 2D floor graphics for circulation, in certain moments become 3D shapes forming urban furniture, play structures and objects for leisure.

The whole system of stripes becomes 3-dimensional, by elevating certain stripes from the ground level, in order to create a social amphitheater with enhanced views to the Xiang River, or even vertical walls which quickly grab the attention of visitors with interesting shapes & patterns, as trendy selfie spots for social media sharing.

The social amphitheater is crowned with a very eye-catching logo of I 长沙 , as main recognizable & distinctive IP image of the rooftop.

To culminate the fun on the rooftop, we included a 12-meters-high spiral slide going down from the rooftop at the 6 th floor to the terrace at the 5 th floor.

Altogether, the rooftop intervention enhances and stimulates the experience of visitors in all senses, and creates successfully a very colorful and stimulating community hub for Kaifu District right on the top of Changsha Beichen Delta Joy City Shopping Mall.
