FUTURE CITIES -
TODAY’S ARCHITECTURE CHALLENGES

We are pleased to give you an insight into the attitude of three internationally successful architects, from London, Barcelona and Vienna, to the topic ”Future cities – today’s architecture challenges.”

Within the framework of ISH, the world’s leading trade fair for bathroom experiences, building, energy, air-conditioning technology and renewable energies, we discussed the question of our life in the cities of the future and the contribution of architecture to quality improvement, which is summarized in the following introduction.

As a world-leading company for premium water technologies and solutions we are a key partner to architects and feel a responsibility to share in changes in our environment

• How can architecture contribute towards making cities more human and bearable?
• How will future cities shape architecture?
• What is the impact of the fusion of analogue and digital for architecture?
• How will new architectural designs influence our future homes?
• What do architects expect from energy- and water-saving technologies?

Presentation and discussion with Herwig Spiegl, AllesWirdGut Architecture ZT GmbH, Vienna/Munich, Benedetta Tagliabue, Miralles Tagliabue EMBT, Barcelona, and Brian Girard, Kohn Pedersen Fox Associates, New York/London/Shanghai. A GROHE event at Forum Panorama Hall during ISH trade fair, Frankfurt/Main, on 16 March 2017.

THE FUTURE IS URBAN
In a fast changing world extreme fluctuations are causing migration into city centres faster than ever before. In 2050 it is predicted that 80 % of the world’s population will live in cities. This creates problems with infrastructure, unemployment, air pollution, water supply and sanitation and access to drinkable water.

We have to redefine the city, but what will the city of the future look like? Solutions require an interdisciplinary collaboration of all involved actors: politicians, city
planners, architects, developers, investors and engineers. Three internationally renowned architects discuss how to deal with these challenges: Benedetta Tagliabue, Herwig Spiegl and Brian Girard.

»The biggest challenge for architects
is to survive in the future.« Herwig Spiegl

CHANGES IN SOCIETY DRIVE THE FUTURE
For Austrian architect Herwig Spiegl, Founding Partner of AllesWirdGut Architecture ZT GmbH in Vienna and Munich, predicting the future is a big challenge. An even bigger challenge is to make the right decisions and survive the future. According to Spiegl, digitalization will have the biggest impact on the future of architecture.
Just take three recent examples: First, an Apis Cor robot just 3D-printed a house in Russia for just over 10,000 $ in 24 hours. Second, in the Netherlands the MX3D robot generated a 3D-printed self-supporting bridge (SLIDE 30). Third, at the ETH in Zurich a bridge was built out of ropes that have been woven by autonomous flying drones.

BIM AS THE REAL COMPETITOR TO ARCHITECTS
However Spiegl adds that the real competitor to architects is the BIM model (Building Information Modelling).
During the Industrial Revolution machines freed men from hard physical work and prompted a move to intellectual work. Nowadays there is not a single human being actually building the cars in a plant. According to a study by Oxford University, 98 % of most jobs will be gone in 25 years except for creative and social work and IT (only 2 %). Architects can be lucky – but are they still creative? Spiegl thinks that the way to progress is in increased efficiency: everything gets faster, cheaper and less energy consuming.

Mr Spiegl envisions a possible future for architects. For once, architecture becomes an investment, defined by a consultancy but drawn and built by machines. Only some architects might survive, maybe for the upper class to design artistic buildings. However in automation there also lies a lot of potential for architecture to reinvent itself.

BE SUCCESSFUL THROUGH INNOVATION
Herwig thinks that there are two strategies for architects to stay relevant. First, be successful through innovation. For example, the text message has been in use since around 1995, until a small company called WhatsApp reinvented its usage. It was about being innovative and thinking differently – something architects have to integrate into architecture.

Similarly, one of Spiegl’s older projects, ‘turnOn’ from 2000, tried to answer the demand for tiny housing spaces with flying furniture that shifts activities from the floor to the wheel bottom to save space. Airbnb has already found a solution: Instead of flexible floor plans we just change floors.

ALLOW FOR USER PARTICIPATION
Herwig Spiegl notes that another important aspect is the integration of diversity. Very often the innovative ideas spark from the bottom of a group and never reach the top. To listen to the users Spiegl and his team took the dating app Tinder as a reference and developed a ‘dream housing app’ called ‘Wohn(t)raum-Tinder’. Now they can find out what people really want and the users can give important feedback.

THE FUTURE CITY IS POLYCENTRIC
Spiegl recommends that instead of following today’s technological inventions we should rather observe society’s changes. Take, for example, the generation gap in music streaming adoption: future generations are not interested in property anymore, streaming the music instead. Spiegl suggests that we integrate our private car in a public car pool to merge the advantages of public and individual transport. This would allow for more space and make cities more liveable. However Spiegl stresses the importance of social interactions since, despite all technological progress, cities have to be social. He envisions that in a polycentric city people could reach every destination on foot and just use driverless cars to get from one centre to the other. These polycentric cities will create identities and the possibility of identification.

»More than technological innovations people want social quality in a city.« Herwig Spiegl

According to Mr Spiegl, we need cities that offer high-quality public spaces, cities that enable chance encounters. More than technological innovations, people want social quality in a city. One of Spiegl’s ideas would even be to keep the land as city property and only sublet it to the developers in order to control real-estate speculation.

LET INHABITANTS DESIGN THEIR PUBLIC SPACE
Spiegl tried to integrate this in his Viennese project ‘Seestadt Aspern’ for 20,000 inhabitants and the same amount of workplaces in 2013. In one of the quarters he and his team designed five houses that created a semi-public meeting-space. A second layer on the outside of one house allows inhabitants to interact from their private space with the public space via balconies. Spiegl concludes that this is how people can actually design their public space.

THIS POSSIBILITY OF FRIENDSHIP IS A GREAT WEAPON
How can architects face lack of housing, inadequate infrastructure, lack of food supply, urban poverty, air pollution and so on? Italian Benedetta Tagliabue, Cofounder and Director of Miralles Tagliabue EMBT in Barcelona and Shanghai, tries to answer by citing her late husband, “You don’t need to be intelligent to be an architect. In fact, if you’re a little stupid, it’s a little better.” She explains how architects can enable a better society and shows a photo of two children in the Santa Caterina Market in Barcelona, an earlier project of hers from 2005 (SLIDE). The kids are of two different races and probably cultural backgrounds. But they both live in Barcelona. This possibility of friendships starting in a public space is a great weapon because it makes people happy, comforted and able to open up to others, offering a chance for society to improve. Mrs Tagliabue says: “Architects can at least make a space better so that others can feel better.”

THE IMPORTANCE OF INCLUSIVE SPACES
Tagliabue tells about the transformation of the market: a formerly dense, grey, gloomy piece of the city that wasn’t connected. It took her and her team about twelve years for the realization, a process of destruction and construction. She imagined this space on top of a roof that would be visible from afar, that could explain ones inner feelings to the outside. Tagliabue regards the market’s big roof as a social act. It turned into a courtyard for everybody from the surrounding neigh- bourhoods.

»Creating inclusive spaces that attract different people and make them feel at home is very important.«
Benedetta Tagliabue

Tagliabue also had to deal with the archaeology. Her team tried to create a relationship between the old walls and the new architecture. Equally important, like the understanding of integration, would be creating inclusive spaces that attract different people and make them feel at home.

OUR MANUAL ACTIVITY IS ALSO A PART OF OUR HUMAN INTELLIGENCE
Mrs Tagliabue has a fascination with handmade objects and incorporated that in her project for the Spanish Pavilion at Expo Shanghai 2010, which were made of wicker. Her idea was to create a literally handmade building that could transform the tools people usually use in the countryside into something that creates a space: a natural environment created by hands. She regards the hand as an incredible tool of communication. When her team from Spain encountered a language barrier in China, the language of hands was always the same. For Tagliabue it is so ancient it will certainly be important for the future. However hands are also thinking tools, they make people think in a physical way. Tagliabue concludes that if we want to change the way we work we have to remember that our manual activity is also a part of our human intelligence. (SLIDE)

THE ARCHITECT’S CONTRIBUTION TO SUSTAINABILITY
Certainly, another important aspect of today’s architecture is the matter of sustainability. Bendetta Tagliabue takes Dutch star architect Rem Koolhaas’ TV Tower in Beijing as an example, using it to explain that it is always the architect who takes the blame. If Rem Koolhaas designs something like that, then inevitably someone will want it. However there is a collective responsibility. She thinks that it is important to be conscious and attentive and to try to generate an architecture that is sensible. For example, the 2016 Pritzker Architecture Prize winner Alejandro Aravena has spoken about how to make affordable houses that can be partly self-built by their users. Another example would be the Catalan trio RCR Arquitectes. Tagliabue explains that they are so local that they didn’t want to move from their home-town studio, in Olot, Catalonia, a choice which enabled them to become universal.

A BROAD HORIZONTAL, SPRAWLING NETWORK
Brian Girard, Design Principal at Kohn Pedersen Fox Associates in New York, London and Shanghai, currently works on the master plan for London’s Covent Garden Estate. In this conservation area gaslights are actually being restored. Girard draws an analogy between Covent Garden and future cities. Both consist or will consist of a broad horizontal, sprawling network, open to interpre- tation and a space where people feel connected and empowered by connectivity. His idea for Covent Garden was to collapse the distance between private and public, to have a great civic space in close proximity to people living there. Mr Girard notes that this is how the traditional city worked and that there is no better typology to influence the design of the future cities.

The district had London’s first square surrounded by houses in the 18th century. The contrast between the fantasy life of the theatre and the everyday working life of the market was one of its characteristic features, a contrast of rough and glamour, an entertainment place. In the 1970s the market moved out and was replaced by retail and restaurants. It became one of the major tourist destinations in Europe. During the time of the market, most of the buildings in Covent Garden were used as storage for fruit and vegetables. Now design and tech firms occupy these buildings. Today the KPF offices are located in a converted pineapple warehouse.

BLURRING THE BOUNDARIES BETWEEN DIFFERENT USES
Covent Garden is a thoroughly evolved mixed-use district with retail, entertainment, residential and office use all in one place. It is a great prototype for the city of the future because the boundaries are being blurred between different uses. KPF’s concept was to identify two hubs of blocks that could serve to regenerate the area. Although successful as a tourist destination, the surrounding areas were relatively dead. As an example, Mr Girard presents Kings Court, a mixed-use residential scheme. Their strategy was to integrate new and old architecture around a courtyard that was carved out in the middle of the block. Girard used three strategies to develop the scheme consisting of a total of ten buildings.

WEAVING A LANDSCAPE BETWEEN NEW AND OLD
The elevations are a weave of historic wall types and buildings and new facades all converted to residential buildings. For example, a carriage workshop turned into an offi building. Now Girard and his team are converting it into a small department store. He explains that the contemporary insertion here is a glazed roof, engineered to be as minimal as possible to underline the historic architecture. It was important that the architecture wasn’t apparent. Girard thinks that this is a progressive idea: “In the future architecture we will frame spaces and environments and not necessarily be the dominant thing people will be looking at.”

»Blurring and breaking down the boundaries between inside and outside will be become more important in the future.« Brian Girard

An important aspect of the scheme was to open the courtyard to the surrounding street to become part of a network of passages throughout the district. Girard and his team planned the routes through the blocks, passing through a series of environments. With this permeable concept they were able to open up the retail fronts of a previously completely closed block. Girard states that blurring and breaking down the boundaries between inside and outside will be become more important in the future. It has much potential in terms of eroding where the edge of public and private is.

Lastly they were building from within in the middle of the block by using the structure of the original properties and the grain of the place, allowing the architecture to emerge, as opposed to imposing the architecture on the context. The contemporary and the old buildings work together as an assemblage: an idea consistent with the modern concept of collaboration that makes cities so exciting.
