Park 5th is a luxury mixed-use building located in New York, and the designer was invited to participate in the design of the residential public area. The lofty ceiling height provided the designer with a broader creative space. With the design concept of "lightness and agility" and a natural color palette as the base, the designer created a subtle division through proportional segmentation, achieving visual balance. The inclusion of luxurious stone elements paired with elegant copper accents adds a noble touch to the space, making it appear even more refined within its warm tone.
