China Overseas International Financial Center is located on Duolun Road in Heping District, Tianjin, in the urban core area along the Haihe River. With the scarcity of core riverside land, the region not only needs high-quality commercial carriers, but also urgently needs to rejuvenate the skyline and enrich the urban interface. To this end, this project is designed with the concept of "Light of Haihe River", using light and shadow, water elements, and material language to integrate urban memory with modern business needs, aiming to create an international business center that combines cultural symbolism and contemporary atmosphere.
As the primary welcome interface, the lobby embodies the urban context through spatial narrative and highlights the spirit of business. The linear ceiling symbolizes the flowing water surface of the Haihe River, enhancing the sense of depth and dynamism of the space; The black marble walls reflect stability and elegance, echoing the depth and history of the Haihe River; The gray stainless steel frame forms the background of the main wall, adding a modern and fashionable atmosphere; The white terrazzo floor material provides clear spatial boundaries visually while enhancing the sense of lightness of the space.
The main background wall of the lobby is designed with liquid marble to simulate the image of the water surface of the Hai River. Its surface texture is like rippling water waves under the reflection of light, sparkling, making people feel as if they are on the bank of the river, feeling the tranquility and agility of the blue waves. Through this unique material language, the designer translates the connotation of "Hai River Light" and skillfully integrates the natural fluidity with the calmness of the stone, creating a welcoming interface that is both noble and poetic.
Liquid marble is first used to outline the direction of the "river channel" with a wire saw, and then CNC micro-carving and hand-polishing are used to carve out layers of water waves, retaining the toughness of the stone while showing flexible flow. The light rises and falls with the water ripples, and the color changes with the time of day. When visitors enter the lobby, the "Hai River Light" provides a tangible and dynamic experience.
The elevator hall contrasts the "linear light" with the "flowing light" of liquid marble, creating a sense of spatial depth and temporal fluidity. Transitioning from a serene water surface to the movement of time, the space embodies a shift from natural imagery to a temporal dimension, reinforcing the symbolic identity of the project as a landmark for contemporary business.
