Southern Cross Station is located in Melbourne, Australia. This project was designed by Grimshaw Architects in collaboration with Jackson Architecture. It was completed in 2007 and won the RIBA Lubetkin Prize in the same year.

Southern Cross Station serves not only as a hub for public transportation but also as a retail plaza adjacent to the central business district. The mixed-use development is covered by repeating wavy roof structures. They offer protection from the harsh sun and heat, ensuring a safe and healthy environment for both visitors and workers. The roof structure is also designed to enable natural ventilation, reducing energy use and preventing negative impacts on the environment.

There are freestanding pods underneath the roof that are used for accommodation service. These structures also help to define space for retail services. The efficiency of circulation for passengers is achieved by a careful arrangement of seating, lighting and information displays.
