The replacement of the old ice stadium opens up the possibilities for a comprehensive redevelopment of the Lido site. The large building masses of the BBZ, stadium, training hall, energy center and the optional high-rise building are all located on the side of Oberseestrasse facing away from the lake. The densification of this area between the railway line and Oberseestrasse continues the existing development and forms a closure to the railway embankment and the Weidmann area.
The building lots facing the lake will be redesigned as green and open spaces with interspersed high-rise buildings. The watersports center and its extension as well as the new open-air and indoor swimming pool give these areas an urban planning framework and define the orientation of the green spaces from the lake towards the new stadium. The density and height of the buildings decrease towards the lake. The city silhouette from the lake towards the old town is clarified again.

The outdoor space concept is based on the qualities of the existing open space axes as well as on the landscape location on the shore of Obersee Lake.
The three existing east-west axes form the basic framework. Oberseestrasse is the central axis. The rows of trees on both sides reinforce the "green character" of this main connection. The addressing of the new buildings is consistently aligned with this axis. The lakeside path and Rietstrasse are dominated by pedestrian and bicycle traffic.
These three main axes are interconnected by high-quality open spaces. An external spatial connection is created between the railway tracks and the lake. The open space axis between the BBZ, the new ice stadium, the Zirkus-Platz and the Lidopark plays a central role in the interconnection of the perimeter within the urban fabric.

The Lido Park develops at ground level from the Lido harbor to Oberseestrasse. On the shore side, the landscaped lakeside path is further developed without the topographical disturbance of the boat garage. The shape and materiality of the gravelled lakeside path frames the Lido Park. Lateral path axes define spatially the park and enable to use it from all sides. The tree-lined Walter-Denzler-Platz forms a spatially effective and at the same time gentle closure to the new stadium building. The planting of the park thematises the transition between shore and land. Water-loving tree species alternate with climate trees that can establish themselves in more urban climates. The linearly arranged trees are composed of different tree species, with the choice of varieties differentiated along north-south and east-west axes.
The Lido Park offers an urban planning opportunity to secure a generous open space for the population within the urban body. The structural densification of the southern quarter can be sustainably developed on the basis of this open space.

The aim of the design is to show a long-term perspective of the area`s potential development, while at the same time implementing the sub-goals in an environmentally friendly way. The expected future warming makes it necessary to think sustainably about the settlement area and to implement measures according to the CLISP guidelines of the Federal Office for Spatial Development ARE.
This is implemented in concrete terms, for example, through the creation of generous and contiguous green spaces, the unsealing of surfaces and water features in conjunction with shady tree planting. From this point of view, the occupation of open spaces by above-ground parking should be visualized critically.
The buildings can be constructed entirely in timber, taking into account regional supply chains. In principle, high-quality materials and equipment for a long service life will be selected for the realization.
The façade of the stadium as a green wall on a trellis construction, which is also used to drain the roof water, has a sustainable influence on the microclimate around the building.
The lowering of the training hall in the first construction phase promises energy-efficient and thus sustainable operation. The roof area will be used as an open space for general use.
