As a coastal city, the history and development of Helsinki are very much linked to its harbor. In particular, as the closest harbor to the city center, the South Port "Makasiiniranta" has largely served as the "gateway to the sea" of Helsinki. As the closest harbor to the city center, Makasiiniranta, in particular, has largely served as the "maritime gateway" to Helsinki, participating to a great extent in the daily life of Helsinki's residents and making a strong first impression on visitors. However, the function and form of the South Harbour have historically changed along with the values and needs of visitors, both residents and tourists, and this time is no exception. 

The design of the harbor is based on this idea, which is divided into three levels: 1. the creation of a flood protection zone with different strategies based on the topography and different characteristics of the city; 2. the refinement and streamlining of the coastal flood protection architecture and landscape, which can exist in different scenarios with a variable form. To build climate-adapted spaces in coastal areas with their flexible forms to maximize the range of activities and functions of people at different water heights. 3. To embed functions in adaptive flood protection spaces to meet the needs of multiple groups.
