We were commissioned to design a product promotion center for a high-tech park, with flexible modular units that can accommodate the multi-uses in the future. The Promotion Center layouts are rectangular in the perimeter and round in the center to maximize the use of interior space and integrate public and private domain in an intricate way. The first and second levels provide open mixed-use exhibition space. Another exhibition space with 360 degree ring-shaped, lifting peacefully 9 meters above ground, provides maximum flexibility for a wide range of product exhibition open to the city.
