The new construction located in the commercial and industrial area of Birkenfeld/Gräfenhausen, near Pforzheim, is characterised by the architectural heterogeneity typical of suburban areas. A number of large function-oriented halls, accommodating production and storage facilities as well as the associated administration areas, were built on the company premises over the years. Centralisation of the administrative areas in a newly constructed office building will allow optimisation of internal processes and communication.
Site
The available unoccupied building site is situated in a prominent location near the entrance of the company grounds. The area is defined by existing roads and a hall. The triangular plot of land and the prevailing topography required individual adaptation of the building design.
Building structure
The design started off as a simple line-shaped structure. In the course of the formal design process, this was transformed into an individual and unique solution for the particular location, which also fits into the general urban planning context. The buckled shape with the open space located in front creates an inviting situation in the north, while forming a small loading area adjoining a production hall in the south. The differentiated design of the structure opens up a variety of perspectives from different parts of the building.
Façade/External appearance
The external appearance is dominated by the monolithic nature of the building volume. This is emphasised by a homogeneous dark plaster surface finish. The mainly northerly orientation of the internal structure is indicated by deliberate placement of large openings in the façade. All of the windows are framed with edging and composed of a rigid glazed section and an opaque ventilation element. The sun protection glazing used for the north-facing windows makes external sunscreening unnecessary, permitting a design that is almost flush with the façade surface. The windows towards the east, south and west are recessed and fitted with fabric sunscreens, which are flush with the façade surface when closed. The orientation-dependent alternation of the two themes gives rise to a subtle variation within the otherwise relatively rigorous grid design.
Zoning/Internal organisation
The three floors above ground are divided into two zones along the length of the building. An asymmetric central wall functions as a separating element. Together with the outer walls, this forms conically shaped internal areas. These offer a variety of changing perspectives, analogous to the exterior and depending on the position in the building. The large room located in the northern part of the structure is the main working area on each floor. Reception and secretary's office are accommodated in this area on the ground floor, while open plan offices take up this space on the floors above. Some individual work areas are obtained without interrupting spatial flow by using thin glass wall partitions. The auxiliary zone in the southern part of the building is split up into significantly smaller units. The access facilities and toilets as well as special rooms with specific functions to complement the main area are accommodated in this zone. These are conference rooms and a kitchenette on the ground floor, and small internal meeting rooms, a break room and confidential individual offices on the floors above.
Construction/Materiality
The contrast between the solid in-situ-concrete construction and the surrounding buildings, mainly consisting of simple pre-fabricated steel construction production halls, is intentional.
The internal division into two zones is emphasised by the use of differing materials. The roughness of the 'grey' open plan office with exposed concrete walls, matching ceilings covered with acoustically effective wood-wool slabs and dark carpet flooring is contrasted by the 'white' auxiliary area finished with smooth light surfaces.
An interesting relationship between demonstratively simple and very elaborate elements is achieved by the choice of materials and detailing.
On the exterior, the composite heat insulation system provided by the dark plaster façade is contrasted by the precise and elaborate design of the aluminium windows.
Inside, effective alternations are achieved with plain exposed concrete walls, acoustic ceilings made of wood-wool slabs, floors with carpets and other covering, in combination with flush doors, individual built-in furniture and special lighting situations.
An altogether cost-effective solution with a special atmosphere has been developed by focussing on specially created individual elements and a reduction in surfaces.
Office concept/Workplace quality
The design tailored to user requirements allows enough spatial flexibility to react effectively to any future changes in the work flow. The variety of open plan and cell offices with gradual transitions from team-oriented to individual workplaces meets the different requirements of everyday work. Individually designed room situations create a personalised environment for each user.
Energy concept
The highly insulated solid construction in conjunction with the northern orientation of the main room space and an almost entirely closed southern façade prevents any excessive introduction of heat. Energetic activation of the thermal mass is achieved by night-time cooling down. Only the meeting rooms on the ground floor are ventilated mechanically. Supply air is preconditioned in an underground duct.
