High-speed train station buildings are now becoming social centers for cities beyond being just a mode of transportation. In addition to being a gathering point that connects different railway networks, they became a focal point where the city and the city dwellers come together, almost acting as ‘the gateway to the city’. In that sense, they are expected to meet different needs other than transportation. In order to meet daily needs, high-speed train station buildings are supported by spaces where people can spend time apart from transportation such as shops, diners, hotels and offices, thus, have become a social center of the city. In this regard, the high-speed train stations have become a multi-layered structure that incorporates different functions. The designers have used different methods and techniques to solve this multifunctional and multi-layered structure. Within the scope of this study, it is aimed to analyze the developed design approaches by examining different domestic and international high-speed train stations, and to develop a design model for new high-speed train stations to be built.
