Having worked closely with major internet firms Google and Amazon in the creation of their high-tech campuses, NBBJ is well-versed in the design of offices for web-based companies. The international firm has now teamed up with the third-largest internet company in the world - Tencent - to design the e-commerce giant's new home in Shenzhen.

Once the Tencent headquarters has been completed, the company will be able to host 12,000 additional employees in its Shenzhen base as the building will almost quadruple the size of its current workplace real estate portfolio. Located in the Shenzhen High-Tech Industrial Park, the towers reach 250m and 192m into the city skyline with a highly memorable design.
