After the long, trade fair-free dry spell, architects and tradespeople are once again longing to meet people on site, to hold new products in their hands and not just be presented to them via video conference. Nevertheless, the world has continued to turn and companies have continued to develop their products. The only question is availability and costs. But if the function, quality and availability are right, the costs tend to play a subordinate role.

After the long, trade fair-free dry spell, architects and tradespeople are once again longing to meet people on site, to hold new products in their hands and not just be presented to them via video conference. Nevertheless, the world has continued to turn and companies have continued to develop their products. The only question is availability and costs. But if the function, quality and availability are right, the costs tend to play a subordinate role.

With the renovation of the Stellinger Höfe in Hamburg and the construction of further buildings, the historical charm of the former railroad site has been preserved. With their combination of masonry and steel construction, the two new buildings blend in perfectly with the industrial flair.

The Mennerich engineering office received support from the heroal project service when planning the numerous heroal systems installed. The service included individual design proposals and the creation of a bill of quantities with the help of tender texts. In order to achieve the desired steel look, all heroal systems installed were coated with a highly weather-resistant powder coating in the color “black grey metallic” with a fine structure. The color used corresponds to the brick façade.

Thanks to the modular design of the heroal C 50 façade system, the profiles can be used with a uniform face width of 50 cm regardless of the construction depth and ensure a harmonious building appearance – even with different thermal insulation and fire protection requirements. The mullion-transom façade system was fitted with insert elements such as the heroal W 72 i block window system and the heroal D 72 project door system, as well as a façade canopy. To protect against direct sunlight, the heroal VS Z sun protection system was used as a partially integrated variant. While the blind box is invisibly integrated into the masonry from the outside, the visible guide rails, end strips and textile screens are color-coordinated with the façade system.

Products:

  • Facade system heroal C 50
  • Window system heroal W 72 i
  • Project door system heroal D 72
  • Canopy system heroal C 50 TC
  • Sun protection system heroal VS Z

Since the introduction of glass fiber reinforced concrete façade products in 2004, Rieder has continuously expanded its products: the spectrum ranges from large-format thin panels to narrow battens and three-dimensionally shaped elements. The biggest driver for continuous further development is the aspiration to make an active contribution to the energy transition. Rieder achieves this by developing new, durable material combinations and radically reducing waste, among other things.

The model for the durability of the material is the opus caementicium, the cast masonry of the Romans. Thepozzolana added as a binding agent gives ita durability that in some cases exceeds that of modern concrete. This is why Rieder is now gradually replacing the cement for its façade panels with natural and local pozzolans. This means that 50 percent of the cement can be replaced in the new 3.0 concrete matrix. For the products, this means a 30 percent reduction in CO2.

In order to reduce waste in the production of the façade elements, Rieder carried out a waste analysis for over a year. Using over 106,000 parts, the percentage of material suitable for reuse was examined. The “pixel” product, a concrete shingle measuring 147 x 240 millimetres, was ultimately developed from the potential shapes. This means that glass fiber reinforced concrete, which is made from mineral raw materials, can not only be recycled, but also upcycled in the form of small-scale shingles.

The extensive renovation and extension of the Lintharena sports and leisure facility in Näfels/Switzerland took around 20 months. The mosaic series “Loop” by Agrob Buchtal sets the tone on the floors, stairs and walls of the entrance, indoor swimming pool, sanitary zones and changing rooms. Round pixels – set alternately in white, gray and black – provide rhythm in the mosaic and define the different usage zones. In the wellness area, white sprinkles accentuate the otherwise black mosaic walls. This creates an attractive contrast.

The mosaic is ideal for the creative and colorful design of wet areas and showers. 15 high-gloss color variants are available, six of which are matt and slip-resistant. The filigree format also makes it possible to cover rounded components. The glaze fired into the natural clay material is abrasion-resistant and gives the colors a long-lasting radiance. The surface is finished with “Hytect”, making it antibacterial and easy to clean.

At Agrob Buchtal, architects and planners can plan individual room concepts digitally, quickly and in accordance with building regulations. This is made possible by the new “Mosaic Designer”. The digital service convinces with its intuitive, almost playful handling. There is a choice of the three mosaic series “Loop”, “Fresh” and “Plural”, which are ideal as pure color system series. The Mosaic Designer automatically creates a laying plan in which each mosaic tile is in the right place.

Manufacturer: Agrob Buchtal

Properties of the “Loop” series:

  • round, filigree mosaic
  • Diameter 1 + 2 centimeters
  • slip resistance R10/B
  • Hytect refinement

Mosaic Designer digital service:

  • easy to use
  • Creative design aid
  • Laying plan at the touch of a button

After the Second World War, destroyed buildings in many cities were rebuilt without taking the historical and urban context into account. This was also the case in Frankfurt’s city center: instead of the impressive corner building from the 19th century, a simple rectangular office building was erected here. In the meantime, the street intersection is once again emphasized by an effective corner building. With a fluted outer shell made of light-colored limestone.

The Frankfurt office of Christoph Mäckler Architekten was commissioned to renovate the inconspicuous 1950s building. The questions posed to those responsible were manifold. The past provided a decisive clue. The existing office building from the 1950s was therefore stripped back to its shell and supplemented with an extension based on the basic shape of the historic building.

From a distance, the outer shell of the multi-storey building appears calm and architecturally restrained. It is only on closer inspection that the detailed design of the façade panels becomes apparent. From a distance, you can see a beautiful, calm, light-coloured shell; a little closer up, the horizontally arranged façade panels become recognizable and, from close up, the fluted surface with its subtle interplay of light and dark.

The street space has regained a great deal of quality thanks to the renovated and extended building with its special corner design. Those responsible have also achieved the goal of creating a bright and friendly appearance with the detailed design and choice of façade material.

How do architects actually design landscapes? We spoke to landscape architect and researcher Daniel Jauslin about how architecture and landscape work together.

It all began with a question: how do architects actually design landscapes? The architect and landscape architect Daniel Jauslin had already noticed during his studies that there are buildings that develop landscape-like spatial experiences in their interiors. He finally answered the question in his doctoral thesis, the results of which he wanted to present to the public – as part of an exhibition. The fact that this would initially take place virtually due to corona was not planned – but it may even have enriched it. Now “If Buildings were Landscapes …” can be seen from March 26 at the Baumuster-Centrale in Zurich. We spoke to Daniel Jauslin about how architecture and landscape work together.

Your exhibition is called “If Buildings were Landscapes” (translated: “If buildings were landscapes …”). What is it about? And: How did you come up with the idea of making this comparison the theme?

The exhibition summarizes the theme of my doctoral thesis, which I developed with my first doctoral supervisor Prof. Dr. Clemens Steenbergen when I came to Delft in 2008. We were interested in what happens when you turn your research with Dr. Wouter Reh on the architectural composition of classical European gardens (2008) around: how do architects actually design landscapes?

I noticed buildings that develop landscape-like spatial experiences on the inside while I was studying architecture in Zurich. For example, the Architectural Association in London, where leading architects such as Hadid, Koolhaas, Moussavi & Zaera-Polo and Bos & van Berkel experimented with landscape in different ways. They designed a kind of inner landscape with the ground, the paths, the views and images, but it was architecture for living, buildings such as hotels, libraries or ship terminals – ultimately entire cities were rethought as Landscape Urbanism.

I analyzed this phenomenon theoretically and practically, i.e. through texts and drawings, and ultimately called it Landscape Strategies in Architecture. After years of academic studies, I wanted to go public with it. And because it is about spatial phenomena, I wanted visitors to be able to immerse themselves in this world with (3D) films and models, so I decided on an exhibition.

The exhibition “If Buildings were Landscapes” is taking place online due to the coronavirus pandemic.

Of course, that was more of an accident at first. The exhibition was due to open in Delft at the beginning of April 2020 and we had already done the scenographic design ourselves in Zurich. We had practically already packed our bags when the head of landscape architecture, Ass. Prof. Dr. Inge Bobbink, called me in March to tell me that the city was closing the entire campus. The students, for whom the whole thing was primarily intended by me, have hardly seen the inside of the university since then.

As a result, there have been a few virtual exhibitions on similar themes – such as those by AMO / Rem Koolhaas at the Guggenheim and Sebastien Marot in Lausanne, in which authors from the fields of architecture and urban planning deal with the countryside. But they live more from their texts. I definitely didn’t want to go back there, as the thesis is already available online as an open source publication. We were more interested in the staged spatial experience; I looked at three VR solutions from Zurich, Berlin and Delft and the SIA International association gave me some financial support. The VR chitects from Delft ultimately had the best system in terms of technology and design and did a very good job.

What does that look like in practice?

Now you can use a laptop or even a smartphone to view the exhibition in advance, as it will be on display in Delft at some point. As an alumnus, I wasn’t even allowed in to photograph it, for example. It’s now like the games my children play online and technically very fast, because all the images are rendered in advance as panoramas. You may remember the old CD-ROM game Myst, which had great landscapes for the time – the technology, which was then called Apple QuickTimeVR, still works in a similar way today.

It was important to us that everyone with Internet access could watch it. Today, of course, kids have VR headsets and VR is much more intense in 3D. Until March 2021, we are building a virtual tour of one of the designs that I analyzed for the exhibition and such headsets: the Jussieu libraries in Paris by OMA Rem Koolhaas from 1992. Unfortunately, they were never built and with plans and models it is also difficult to understand how intensively this building would have merged with the entire city of Paris to form an urban landscape. We can bring this to life with today’s 3D GIS technology. On the screen or on your kids’ game headsets.

Nevertheless, not everything is possible on the Internet. If you want to see the 3D video installation “If buildings could talk”, which Wim Wenders staged with SANAA, you still have to come to the exhibition and put on specially disinfected glasses. I don’t yet know whether the exhibition will be allowed to take place outside in Zurich’s Bellvoir Park as an alternative or whether or when visitors will be able to see the models at the Baumusterzentrale Zurich, the Atelier Néerlandais in Paris or finally at the Delft Faculty of Architecture. It remains exciting to have an exhibition in the year of the pandemic.

What is your personal stance: should architects think more about landscape or should the disciplines work more closely together?

Both are important – and I practise both. My first training was as an architect, but I have always felt that there is more space in the landscape – literally and symbolically. For me, design strategies of the future were to be found in the landscape. This first brought me to landscape myself, where I was allowed to design a park in my first major project at West 8 Rotterdam: The Arteplage of the Swiss national exhibition Expo.02 in Yverdon-les-Bains. Alongside my mentor, the landscape architect Adriaan Geuze, I worked with many good architects such as Mateja Vehovar, Liz Diller, Tristan Kobler, Ric Scofidio and my brother Stefan Jauslin.

I first built houses with my later partners Hans Drexler and Marc Guinand, but with our first house in Pigniu in Graubünden, we were more interested in architecture as a vehicle for living in the Alpine landscape. Peter Eisenmann told me in an interview for my dissertation that he was interested in the light between the trees – loosely based on C.G. Jung … I must have grown into the green, to the side of the light.

“We cannot remain in the traditional autonomous disciplines.”

How does that manifest itself?

I crossed the boundaries between disciplines almost every day: As a landscape architect in Delft, I once taught architects and engineers how to build bridges. I have taught design at all levels of landscape architecture courses at the universities of Delft and Wageningen. Defining disciplines may help to achieve clarity, but when it comes to solving major urban planning tasks and the huge challenge of climate change, we cannot remain stuck in the traditional autonomous disciplines.

In practice, my office, DGJ Landscapes, now works together with very different, often specialized architectural offices in competitions. I consider myself lucky that we are always involved right from the start and that the landscape design no longer only concerns the surroundings after the building has been completed, but is an integral part of every good overall design – even if not every building has to be an internal landscape, as in the exhibition.

“We have to understand architecture as a system.”

What can architects learn from landscape architects?

Architecture has become incredibly specialized. Perhaps precisely because of the enormous increase in the complexity of the problems it is supposed to solve, architects are retreating into the refuge of an autonomous discipline. I think that’s fatal; you can’t plant a tree from the forest in a pot and put it in a museum. In the same way, we must think and develop buildings as organically interwoven with their context on all levels, in the cultural urban sense, in the technical sense and also with regard to the natural living environment, to which we still belong despite our spiritualization.

Gottfried Semper, the important architectural theorist of the 19th century, spoke of metabolism. He was referring more to historical tents as precursors of the Baute. As a formative classicist, he was very critical of his contemporary forerunners of green architecture, such as the green glass palaces popular in Paris and London at the time. But actually, metabolism is a key concept for us today: we need to understand architecture as a system that is connected and interacts with the living world of all species, including flora and fauna.

But we are only just beginning to do this, so there is still something to learn for several generations to come. Marot told me at one of his lectures in Lausanne that he essentially teaches architecture students at the EPFL what permaculture is. We probably still need to introduce this into landscape architecture, but the fact that nature-based agriculture is taught at a polytechnic for architects shows that we are further along today.

One of the areas of the exhibition is called “How to survive the Anthropocene” …

If you think further than just about the landscape experience in buildings, you come up with a potential of holistically conceived architecture that has hardly been exhausted. However, this idea stems more from my criticism of the buildings by Koolhaas, Eisenman or SANAA that I show:

Today’s architecture is, after all, incredibly wasteful and one of the most important causes of climate change. Concrete buildings, which modernism has virtually sanctified for an entire century, are, as we have known since the 1970s, all climate sinners. In Holland, people are now discussing concrete shame at specialist conferences (as they do in Scandinavia about flying shame) and, as almost everywhere else, are rediscovering timber construction. But when I started out as an architect in Holland, a wooden deck like the one on our red bridge in Amsterdam was almost unthinkable. But it’s not just about optimizing the metabolism in construction, for example with wood or other renewable resources, it’s also about the local conditions.

It is even about a fundamental attitude: planners in architecture have an inverted concept of time. As service providers, we concentrate on costs, deadlines and a concept of quality that is restricted to the marketable real estate object. Planning only lasts until the keys are handed over and the warranty work is completed. But we should build something with our cities that will outlive us by generations, like a forest: something that takes root locally and keeps growing anew.

“The intellectual potential is there.”

What are the instructions, the “how-to”, that you provide in your exhibition “If Buildings were Landscapes”?

In the virtual exhibition, I first show approaches in the form of links to videos of the many sustainable ideas and concepts. In the real exhibition, workshops were planned with young designers, which we wanted to partially replace with virtual workshops. Ultimately, I think there are two possibilities: Either architecture insists on its autonomy and closes itself off to the huge challenges of protecting nature and the climate. These will then be solved by specialized engineers, who are already increasingly in control of the built environment. Architecture may thus become a nice side issue, an interesting pastime, about as relevant as playing chess. Or it could reinvent itself, and an integral view of the surroundings and an understanding of the buildings as parts of a living landscape would be conceivable.

The intellectual potential is certainly there, but the Western Greco-Roman tradition has developed two millennia away from nature. I hope we still have time. That is why we are looking for solutions as to how architecture could survive the Anthropocene, our age in which humans have reshaped the natural development of the world in geological time scales.
