The thesis aims to design a floating structure complex at the Zurich's Lake, which will house cultural and entertainment activities. The complex will be available to citizens of Zurich to use throughout the year by seasonal changes to usages.

The area that will facilitate the complex is located at the west suburbs of Zurich, in a green area rich with places for daily activities along the lakeside.

The aim of the thesis, as well as the location chosen to house the complex was selected based on two main reasons.

Firstly, the natural connection of the city with the lakeside settlements and secondly the lake's water level changes that assigns the area (ήprovides the area with) an interesting singularity.

The usages of the complex are an outcome of the natural connection, since the platform would house activities that reinforce existing ones in the area or fulfil some needs by adding new ones. The various usages led to the design of a floating structure which will connect to the mainland and some floating ones that will move around the settlements.

The changes of the lake's water level will define the platform's form which will interact with its environment and with the users of the area. The changes of the form will create a fluid interactive structure which will allow to the lake's water to flow through the platform and create new parts of the lake. Moreover, the uses of the platform will be influenced by the alternative scenery which depends on the time of the year.
