Creating meeting places
One crucial element the architect singles out in terms of living quality in densely populated environments are rooms that can be used collectively, expanding individual living spaces. Take the formerly anonymous stairwell for example, which has become a meeting place; or the roof terrace that is now a communal garden. "The willingness to share has grown in recent years," Salathé remarks. His architectural firm for example has integrated common areas such as a fitness room and a kitchen into the plans for a high-rise project in Aesch, Switzerland. He sees a great deal of potential for the future of sharing in the next generation of architects. Many of his students, he says, have grown up with shared spaces and routinely include them in their thinking.
Another aspect that Salathé considers central to the future of building is neutrality of use. At present he sees a trend to convert offices into living space, though this might easily change again. "That's why we need to think about flexibility not only on the small, but also on the large scale. Certain floor plans work across many generations because they are adaptable. But if the apartments are over-specified, i.e. too precisely defined, it doesn't work in the long run," he says. As a result, buildings would have to be demolished.
The future is openness
For these reasons, flexibility is required at all levels. But with all the densification, do spacious and open living areas even have a future? Salathé is convinced that openness will remain an important element of architecture. There is a need for people to be able to get together in a large space. "The kitchen will probably replace the living room as the focal point of the household in the future," he adds. In the future it will be essential for open living spaces to be adaptable to many different situations. In his view the experience of the pandemic has demonstrated this impressively: "No one wants to work, cook and eat in the same room all day long."
Salathé emphasizes that when considering the future of housing, it is important to take into account sustainability and the preservation of resources. It is important to put more work into existing housing stock and not just to optimize new constructions. As an example, Salathé has converted a former clinic in Muttenz, Switzerland into a student dormitory. In his opinion, "the strategy of replacement construction needs critical questioning". If architecture wants to be sustainable, it must abide by the principle "Think rather than demolish".
