_Campus City

With the new development along Berliner Straße, the old model of the functionally separated city for Neuenheimer Feld in Heidelberg is being abandoned. The development perspective of the knowledge society now offers the opportunity to link places of knowledge production and knowledge transfer with the urban space and the urban society of Heidelberg in a new way.

The Neuenheimer Feld is moving closer to the city. The permeability of the campus must be preserved and its "neighborhood edge" must be made permeable and attractive. On this basis, the present urban development concept makes a significant contribution to the further development of the European city in general and the development typology of the most diverse places of knowledge in Heidelberg in particular.

Urban Space Open Space

_Level of the City as a Whole

The dimension of the new urban open space "Platz der Wissenschaften" and its most important urban building block, the "House of Nobel Laureates" not only references the size and dimension of Neuenheimer Feld, but also responds to the city street Berliner Straße and the new corporate headquarters of Heidelberg Cement opposite.

This clearly distinguishes all three existing campus entrances. Even more, the combination of square and house equally solves the requirements of a campus gateway as well as a bridgehead and creates an important address for Neuenheimer Feld. The urban design differentiates between the square and the park (Römberbad), creates a diversion of the Jahnstraße and sets new paths and visual references to the Neckar and into the campus. In addition, a significant, architecturally refined landmark, the future "House of Nobel Laureates", can accentuate Neuenheimer Feld in the urban silhouette of Heidelberg's science city and enrich the urban spatial effect

_level of the district

The urban planning goal of the design is to realize more than just an open and inviting "edge" of the university quarter. The Heidelberg urban body exemplifies in three places how the spatial proximity of university and urban society can be experienced in public space. The University Square and the former Anatomy Garden, both located on the main street, have become an integral part of the city layout as representative city squares. Their names also

represent the special connection between the city and knowledge. The forecourt of the former Krehlklinik as the end point of Römerstraße, again located on a main street, Bergheimer Straße can continue this urban tradition.

The same goal is pursued by the urban design for the development of the south-western corner of the Neuenheimer Feld campus on Berliner Straße. With the new "Platz der Wissenschaften", an important city square is being created on an important city street as the entrance and prelude to the science quarter.

The memorandum for the international building exhibition "Wissen schafft Stadt" (Knowledge Creates the City) refers to the urban proximity of the university and urban society. "Sciences that want to be a tangible and central part of urban society need spatial proximity to other uses for this." It goes on to say that at the neighbourhood and urban district level, it is precisely "open and inviting neighbourhood edges, the bridging of interstices and barriers, and main thoroughfares leading through as connecting elements and perceptual space" that take on important aspects in the urban-spatial linking of university and city.

The new "Platz der Wissenschaften" with its shady, tall pine forest serves as a generous, atmospheric urban space for arriving and orienting as much

as for meeting and communicating.

_Level of the buildings

Four buildings are arranged on Katharina-Windscheid-Platz. A square that could be named after the first woman to earn a doctorate in Heidelberg, a pioneer of women's studies. This neighborhood square serves primarily as an access, communication and connection space between the research facilities of the Max Planck Institute and the facilities of Heidelberg4Life. The square not only functions after the completion of all construction phases, but also fulfills its task while retaining the previous street layout.

The development concept with only three research buildings and the representative "House of Nobel Laureates" creates a logical gradation and differentiation between the public squares (Platz der Wissenschaften, Katharina-Windscheid-Platz) and the "private" gardens or terraces (Jardim Secreto, listed green space, Max-Planck-Terrasse). Similarly, the development concept underlines the desire to counteract a so-called "Verhäuselung" of Neuenheimer Feld.

The ground floor zone is the point of intersection or contact between public space and the respective knowledge institution. Thus, the design of the foyer zone and its use is of particular importance. The IBA Memorandum states that "it is precisely through lively and visible ground floors, building entrances

and the interlinking with the courtyard and garden that the prerequisites for an attractive and

safe public space can be created". For the "House of Nobel Laureates", one could imagine, for example, a permanent exhibition on the subject of man

science, which, among other things, also establishes references to the lives and works of Heidelberg Nobel Laureates.

Research Buildings

_Concept Function

The research buildings for MPI and HD4L are all based on a building depth of 25 meters as a three-bundle and offer maximum flexibility in occupancy. All buildings offer non-exposed laboratories in the basements as per the requirements. The first two construction phases for the MPI and HD4L are each four storeys high. The new MPI building is connected to the historic building via thermally closed "bridges". In the first building phase, the MPI will have three underground floors, which will extend to the south. Both ground floors are to be elevated. The foyers of the new buildings, as well as the historic entrance of the MPI, are "neighbourly" to each other. The first construction phase HD4L offers additional space for other uses on the ground floor, which can be accessed from the square via arcades. The top floor also offers further opportunities to create synergies with other users or stakeholders.

While the 2nd construction phase HD4L, which adapts to the existing building of the university with its three floors, closes the listed garden to a "jardim secreto", the 2nd construction phase MPI creates the "Max-Planck-Terrasse" on the Neckar. Three underground floors connected by atriums maintain the historical building's prominence in the urban landscape. In the topography of the Neckar riverbank, the 2nd BA appears only with a wall, which takes up the height difference and accentuates the spatial edge to the river.

Mobility Traffic

The permeability of the Campus Neuenheimer Feld, is to be maintained and expanded, especially for pedestrians and bicycle traffic. To this end, the urban design allows for new pathways in all directions, taking into account existing connections. Particular attention is paid to the connection to the Neckar, which is made possible by new paths to the west and east of the site of the Max Planck Institute.

The underground car park of the MPI will be made possible via Kirschner-Strasse and a spur road to the east of the surgery. Thus, the newly created Katharina-Windscheid-Platz remains car-free and enables a representative entrance situation for both research institutions already in the first construction phase.

With the renaming of the former tram stop "Jahnstraße" into "Platz der Wissenschaften", its (barrier-free) integration into the urban space between the square and the Heidelberg Cement headquarters opposite will also take place. Thus the place marks the university in the line network of the city of Heidelberg and thus expands its special significance in the city layout.
