Developers in Germany are currently rediscovering the residential high-rise as a modern, high-quality building type. At the same time, the format has to be adapted to the relevant urban context and “reinvented” as it were.
Located at the western end of the Europa Allee, this residential building occupies a rather special position between the urban space and the countryside. What’s more, its high-rise nature emphasizes its presence within the city’s fabric. The architects made a conscious choice to ensure the main body of the building does not seem like a standalone development. Rather, it continues the urban context and slots into it, developing into its own independent structure in keeping with its special position.More
As you approach the Europa Allee, the high-rise forms a clearly defined slab: Its western front appears like a tall, slender prelude to the Allee, while along Eppenhainer Strasse the building emulates the perimeter-block style of the surrounding developments. To the south, townhouses are incorporated into the overall plans, and these take their cue from the existing terraced housing to the south.
By quite literally “elevating” the surrounding structures in a literal sense, the building forms an “urban context high-rise” that plays with the ambivalence of urban contours and individual landscaped housing and open spaces, consciously transferring these into two distinct views or “faces” of the building.
On the outside, the flat façade clad in white limestone presents a monolithic, contemporary shape. At the same time the playful design of the window openings, which extend over two floors, creates a nuanced grid structure that makes it hard to distinguish the individual levels and toys with perceptions of the building’s scale.
In contrast to the smooth, urban outer façade of the building ring, the inside forms a soft, polygonal and richly varied structure. Individual incisions to create balconies on each and every level ensure a world of balconies and loggias offering any number of ways of being used. Extensive glass façades for the living spaces also provide for a smooth transition from inside to outside, while broad, permanently installed plant pots incorporated right up to the top floors ensure plentiful greenery in the outside areas.
The perimeter block style makes it possible to combine the qualities of classic residential floor plans with the advantages of a high-rise. Here, the architects have ensured that the floor plans are oriented towards as many sides as possible to create a high-quality sense of being part of everything thanks to the clear views in all directions. In keeping with the complex mix of typologies and its multipurpose façades, the building also contains a variety of housing formats: Ranging from terraced houses with gardens to classic apartments with between two and five rooms and even a penthouse, the high-rise offers a mixture of big-city living for a high quality of urban life. Semi-public areas like the entrance hall and the direct link to a large public park also provide for plenty of quality time for the community.
Use of sustainable technology and a sustainable energy balance were also one of the premises of the planning. Hence, AXIS is one of the first projects in Frankfurt to incorporate a heat recovery system from waste-water and to be planned in line with the KFW-55 standard (previously not common for high-rises).

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.
Various objects and arbitrarily stacked boxes as a starting point
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.
