The design envisaged an independent extension in the north-western area of the State Library, which would only be connected to the old building by a footbridge. The old building was therefore not affected by massive structural interventions and could be used during the entire construction period without disruption. This also made it possible to avoid costly relocation of the holdings. The six-storey annex building will house all functional areas with a high frequency of use, while the existing building will offer reading areas for quiet and concentrated work. The reading room thus clearly becomes the centre of the entire ensemble.
The light Béton brut façade of pigmented white concrete, which characterises the façade, gives the building a friendly, inviting character. Together with the library square in front of the building and the large staircase, this creates a visually appealing overall impression.
The axis to the New Palace is clearly visible. The design was based on the boulevard idea for the Konrad-Adenauer-Strasse, which will be implemented in the near future.
The Württemberg State Library building in Stuttgart is one of southern Germany’s preeminent architectural achievements of the 1960s. The building is impressive due to its generous sequence of spaces as well as the thoughtful choice of materials and the high quality of its architectural implementation.
The annex building now directly fills the corner of Ulrichstraße and Konrad-Adenauer-Straße. The pavement for pedestrians, which begins with the tree-lined avenue at the Staatsgalerie and currently ends at Ulrichstraße, will be extended to the State Archives building and hopefully continued to Charlottenplatz at a later point in time.
The new building, which roughly adopts the ridge height of the Wilhelmspalais, is set apart from the original building to provide space for a path between the two buildings that enables a link from Urbanstraße to the lower level of the building complex. Urbanistically, the cubic volume of the old reading room, which now occupies the middle of the new plaza, forms a relationship vis-à-vis the central projection of the palace across the street. Ample steps establish a connection to the new pavement at street level.
The building can now be accessed at both levels. The lower level will also house the future cafeteria, which opens onto the street and can operate independently of the library. The main entrance to the library is on the level above. From there, library-goers reach the lobby with the requisite information counters, entry points to the controlled access zone, the book return, and a hall and exhibition area that opens out to Konrad-Adenauer-Straße. There, some of the spaces are two stories high, because for economic reasons the ceiling heights of the typical stories are considerably lower.
On the first floor, which is accessible via a staircase within the controlled access zone, the connection to the old building is situated directly at the top of the stair. The central part of the floor is occupied by shelves. Along the length of the building on both sides, open workstations are lined up in rows towards the hall, with supplemental administrative rooms opposite them. An atrium visually connects this level to the other three floors above. On the second and third floors, the reading desks are located along the zigzag exterior walls. The top floor is, by contrast, laid out in reverse: here the reading desks are placed in the middle – because on this level, the folded roof structure enables us to direct daylight into the center of the building.
At first glance, the new building has the appearance of an independent entity. The fact that it constitutes an annex to the old building is made clear by the choice of materials, dominated by exposed concrete cast with board formwork, creating echoes of the old in the new building.

Besides dealing with ongoing projects, regular participation in competitions is essential to their work. Aside from being a chance for a new commission, it is an occasion for a stimulating and profound examination of a present-day challenge. Sketches showing a first general concept, a precise analysis of the area and working models are all essential steps for them.
Among the competitions won in recent years are; the Volkstheater in Munich, the dialogicum, the Historical Museum in Frankfurt a.M. and the Municipal Museum in Stuttgart. Also, Annex to the Württemberg State Library in Stuttgart, the Historical Museum in Frankfurt a.M., the Office and Business House Kaiserkarree in Karlsruhe and the Municipal Museum in Stuttgart. Also, the Educational Centre in Lörrach, the Cloister Hegne Marianum in Allensbach, the Art Museum in Ravensburg, the Diocesan Curia and archive in Rottenburg and the Hospitalhof in Stuttgart are all important projects for them which were acquired by competition.
Their projects are mainly realized in the fields: Office buildings, authority and administration, leisure and sports, health and education, culture and church, housing, the industry as well as urban planning.
The annex sought not only to accommodate new programs but also to improve a complicated urban situation characterized by loosely related buildings and a heavily used street.
A new underground parking garage forms an entrance square that connects the new facility to the original library and the archives building on the same level, and will in turn link up with a future pedestrian boulevard.
The reading areas are organized around an austere central void and are generously endowed with natural illumination thanks to skylights on the sawtooth roof and a zigzagging perimeter of floor-to-ceiling windows…
