Gateway Gardens is a clearly defined development site serving various commercial purposes in an airport-like format. The lion’s share of the development comprises office buildings, while the communication zones can be configured as required and the type varied through modification in different ways. The urban structures are clearly ordered, on the one hand, yet are interpreted differently depending on the construction site. Specific elements are the higher buildings at the relevant access points to the development.
The MK3 construction site lies at the northern entrance to the development and directly adjoins an area of dense woodland. The particular location of the plot means it has been interpreted as a transition to and a link with this forested area. In keeping with this, the building’s structure has direct associations with the sort of images that might come to mind for differently structured landscapes and forests. The result is an edifice that is notable for its sculptural style and which befits its gateway location, staking its claim appropriately in this seemingly heterogeneous context.
In terms of building type, a variety of different spatial formats, overlaps and intermediate spaces have been created. What emerges is a richly diverse office-world with a pronounced coherence in terms of indoor and outdoor spaces; while it may be hard to decipher at first glance, it incorporates aspects of perception, interaction, flexibility and an emphasis on process over finality.More
More specifically, the building boasts an amorphous underlying ground-plan that efficiently dictates the spatial sub-division across the four units of 400 square meters each. The structure of the building itself emerges from the rotation of this ground-plan around a fixed core, whereby the rotation is sometimes greater and sometimes lesser and – for example in the entrance hall or in the terrace areas – results in nuanced spatial situations. These areas are oriented according to sight lines and views over the surrounding area.
The façade leaves much scope for further development, but even with the simple façade formation, the elaborate shape of the building renders it remarkable in terms of design.
The complex geometry also creates the conditions for an efficient and modern office structure: The wrap-around office zone is based on a 1.35-meter grid and can be used flexibly, starting with offices straddling two axes and transitioning into group offices, combination zones or flexible meeting or lounge areas – these can all be arranged as requirements dictate. Through modification of the amorphous ground-plan, the ancillary areas close to the core of the building can be adapted for specific requirements in future.
In the current elaboration, the building’s geometry has been given greater precision:
The overlap of the floors has been enhanced to maximize daylight in the office spaces. The areas facing the hall present a rather special situation. The stacking of the floors has been optimized for load-bearing properties, while the core zones and the technical shafts have been defined and outlined in greater detail.
The underground carpark has been developed based on the loads stemming from the ground floor. Without major load redistribution, 103 parking spaces could be created for each floor, but depending on the specifications, the underground parking facility could be expanded to embrace two levels.
The building has also been surveyed for a potential increase in height from 60 to 80 meters. The two fire escape staircases already in place mean no additions are necessary other than the installation of two lifts, and the structural principles also allow for the building height to be raised without any adjustments. Hence, the building can be developed into a higher tower as required with no particular changes made to the building structure, especially since the main body of the building with its varied and diverse structure is ideally suited to a height increase.

The architectural expression of the buildings we have designed varies immensely. Nonetheless, they are based on an explicit architectural stance and share the same design approach.
As we see it, an architect should pay close attention to the actual conditions and allow them to develop fully. The logic of what is real imposes limits on the architect’s ideas, and any subjective thrust to the architecture is reduced to a minimum. After all, finding is more important than inventing. At the same time, it is important to transcend the existing situation intellectually and this ultimately transform it into an architectural design. It follows that our fundamental concern is to bear with the ambivalence between the actual parameters and what they inevitably translate into and come up with something beneficial in the process. To do this you must be capable of seeing precisely what already exists, be fascinated by it, but also let it inspire you to go beyond it if necessary.
This is why our concept entails us working with perceptions, images and associations, combining them with the practical parameters of the respective brief.

We begin each design process by researching and thoroughly analyzing the specific features of a place and the brief. This involves exploring historical, cultural and symbolic layers and teasing out their vibrancy. Based on these insights, we collect all the possible associations that occur to us. Typically, these thoughts are closely bound up with the particular features of the place, existing architecture and brief. They emerge from a precise observation of everyday things, their arrangement and significance. These features might be furnished interiors or the items that generally shape a space, but can equally be existing, urban situations, the historical layers of a building or the history of a place. We then translate these authentic spatial structures and constellations that have developed naturally into model studies with a view to revitalizing the space at our disposal as perceptual space, space for reflection and space for social interaction.
In our design process the analysis of the existing circumstances merges with the transformation of existing situations or buildings. Specifically, we rely on intellectual associations and the images derived from them. What at first sight might appear to be a kind of ready-made becomes the basis for a new reality, which neither ignores its position in a given context nor the conditions under which it evolved. This approach also emphatically draws on past building typologies and techniques.
As such, our approach to architecture is based on our essentially seeing everything we do as a transformation or a conversion of existing situations. This is why the buildings we design respond sensitively to their immediate surroundings and urban context. At the same time, they also develop a sculptural impact. We resolve the seeming contradiction this produces by applying specially developed methods that are established practice in the world of contemporary art.
For the project Reading Room at the Museum für Moderne Kunst Frankfurt an abstract version of the study of an “intellectual compulsive hoarder” was created using multiple stacks of books.
Apart from realizing individual projects we also continually develop spatial studies that are not commissioned and in which spaces are played through on varying scales and explored in an exemplary manner.
Drawing on an idea from concept art we employ calculated experimentation with levels of perception and chains of association to kick off the design process; a method that produces solutions which might seem natural but are also surprising.

Things suffused with human experiences, spatial and urban constellations are transformed graphically, sculpturally and architecturally.
Whether designing a new building or converting an existing one we place the focus firmly on perception – particularly regarding the ambivalence of mass and space, concreteness and abstraction. Existing buildings and constellations are infused with diverse social experiences that trigger specific associations. By identifying and analyzing their complex significance vibrant uses and means of social interaction in real space emerge. This creates a new view of places, buildings and things that in turn stimulates new ways of combining various images, atmospheres and uses.
We also engage in our own spatial studies – and have elaborated them over the years. They focus on examining and exploring examples of urban and urban planning concepts, spatial structures, building typology structures as well as artistic issues.
Spatial studies and projects
Over the years we have developed the following spatial concepts drawing on the methods described earlier. Through a series of sculptures, model studies and drawings we have examined how spatial concepts can be developed and realized not only considering the relationship between line, surface and space, but also between drawing and sculpture, representationalism and abstraction.
The steel sculptures by Florian Schlüter are conceived as walk-through drawings transposed into the realm of the three-dimensional. They revolve around the ambivalence between concepts such as mass and space, concreteness and abstraction and are aimed at exploring the authenticity of the everyday. These inconsistencies become integrated into later architecture projects as fundamental aspects of them.

Studies of urban space
In various studies of urban space, Claudia Meixner employs drawings, paintings and models to penetrate the relationship between mass and space, space as a complement of mass and space, mass and intervening space. Her starting points are both abstract but also specific urban constellations whose given sensual and material design become the point of departure for a transformation that can culminate in a new take on reality.

Moreover, a series of model studies and installations are used to realize potential buildings. Complex spatial concepts are developed through addressing issues on the relationship between shell and core, the importance and function of interstices and elements in space.
Here furniture or furnishing elements in interiors are taken as the starting point. In this model study the constellations that have become usual in everyday life correspond with individual walk-through spaces in a large surrounding space. It is possible to experience the elements and their relationship to the overall space as well as the relationship between the intermediate space and the space as a whole.

Model of accumulation/stacking
Model intermediate space
In a first model study the starting point was the seemingly chance accumulation and stacking of things. The individual elements in the model represent interior spaces that can be walked through and form intermediate space.
The point of departure for another model study is the shaping and selective filling of intermediate spaces through a stacking and layering of various objects in the space. The relationship between positive and negative is reversed, while that of the volume and mass is redefined. The intermediate space becomes walk-through mass.
In addition to the afore-mentioned conceptual parameters, when realizing projects the practical parameters of relevance to the architecture also come into play and influence the substantive concept.
A whole raft of structural means contribute to the success of a sculptural edifice that expresses tranquility and agitation, gravity and lightness, stability and instability, depending on the overall concept.
In designing a pavilion for Expo 2000 the starting point was the geometry of a “simple house” with a saddle roof, a single interior space and several “items of furniture”. By enlarging it ten-fold the things morph into archetypal symbols. Perception per se is addressed and a new perception of the architectural space and the objects in it is created. Depending on the viewer’s angle the house, interior space and garden appear either symbolic, concrete or abstract.

The concept for transforming this residential building developed from the necessity to extend and structurally improve an archetypal house. A new sheath was created that encompasses the entire house. Diverse spatial constellations were produced within the cubic sheath architecture that experiment with the relationship between interior and exterior spaces and the intermediate spaces created as a result.

As part of a project for Artemide, the shapes of several of the manufacturer’s luminaires were regarded as ready-mades, reduced to their essential components, merged with one another and cut out of a compact mass as a negative form. Through the play of light and shadow the resulting polyvalent volume produces a special spatial atmosphere and triggers diverse associations.

The special nature of the place and the reduction process is made evident in the partial dismantling and conversion of the Dornbusch Church. A new wall marked with indents and molds of the old church and elements that had been removed were used to form a sculpted structure. What is absent remains present in these molds. The perception of area and space is activated and the recollection of its earlier state reinforced.

In architecture as we understand it everything is basically transformation. We see our task as controlling the ambivalences that emerge during a transformation of an existing structure. This is not only easy on physical resources, but also revitalizes sensual, intellectual and ultimately cultural resources.
