In order to emphasize the "natural" tone of the building, the RÖDER team designed a dark brown profile and pioneered a wood grain facade system, adding it to the original glass curtain wall to echo the overall structure, which not only blocks out excessive natural light and ensures soft overall illumination, but also adds to the "original tribal feel" of the building, integrating it into the broader landscape and reflecting the adjacent buildings. The roof height of the tennis hall is 12.5 meters, which fully meets the International Tennis Federation's regulations. The inner roof of the tennis hall can achieve thermal insulation and heat preservation.
