Mehr Platz als Haus
Mensa Schulzentrum Stadtmitte, Leonberg
Mensaneubau für das Schulzentrum Stadtmitte in Leonberg – Die neue Mensa ist Dreh- und Angelpunkt des gemeinsamen Schullebens, Treff- und Sammelpunkt, Ort der Begegnung und des gemeinsamen Essens. Als zentrale Anlaufstelle wird sie für alle drei Schulen zum gemeinsamen identitätsstiftenden Ort. Die vielfältigen Nutzungsanforderungen des sozialen Schullebens werden durch verschiedene Bereiche erfüllt, die sich über die gesamte Platzfläche zwischen dem Albert-Schweitzer-Gymnasium und der Gerhart-Hauptmann-Realschule verteilen – es bildet sich ein räumlich funktionales Kontinuum zwischen Innen und Außen.
More place than house
The building creates several interior and exterior zones that are used to fulfill the various social needs of the two schools. These interior and exterior zones converge and blur the division between outside and inside. This is evident when one looks at the materials used for the flooring. The dark asphalt surrounding the building continues into the interior through the entry and, thus, combines the external and internal circulation spaces.
The internal circulation contains the main entrance, the dining counter and queue, and allows for continuous movement between the three core functional spaces. Within these core spaces are two areas for dining and meeting, and a third space for food preparation and other necessary services. By joining the core spaces in this way, the total area of the building is minimized, but allows for a flexible use of space and a generous area for circulation.
“The new cafeteria is the hub of the school life together, a meeting place, a gathering place, a meeting place and eating together.”
Open space continuum
The special zones created by the internal functions are also reflected in the interior materials. On the ceiling, black bands mimic the circular forms created by the building shape. Within these black bands, small, cylindrical, aluminum tubes of differing circumferences were used to create a drop ceiling that disguises the artificial lighting above. Moveable partitions also follow the circular forms within and allow the two dining areas to be closed. This further clarifies the function of each zone and its relation to the overall building shape.
On the exterior, the façade consists of a system of open and closed floor to ceiling panels paired with exterior wooden supports. Here the rhythm of the vertical columns reinforces the undulating form of the building and the open glass façade creates a visual connection to the outdoors. The shape and orientation of the building was designed to maximize solar gain and for this reason the southern and eastern sides of the building consist of the main dining areas and have an almost entirely open facade.
Economy and prefabrication
The generous amount of natural light that is created by the open façade allows for the relatively small use of artificial lighting and contributes to making the space feel open. Natural ventilation was also incorporated into the façade and is used in combination with a mechanic ventilation system. By optimizing the relation between façade area to ground surface, loss of temperature is also minimized.
On the western end of the building, the façade is closed surrounding the service core, and skylights are used to provide natural light for work spaces. By using a regular façade in this way, the elements needed for construction could be simplified and a large amount of the construction could be industrially prefabricated. The simplicity of the building form is then tectonically expressed with in the construction and overall design. By uniting these elements, the building gains clarity and functionality that was beneficial in linking the two schools.
