We answer the most important questions about architecture. "Trends and the future" is our first keyword: The development of tomorrow's residential construction Knowledge of trends in residential construction is essential for us architects. We are at the beginning of the product development process: it usually takes around three years before a flat planned by us is occupied. The useful life of a flat in its planned form should be around 30 years - ideally without additional investment in the internal organisation. For sustainable planning from the user's or landlord's point of view, a long observation period must therefore be taken into account. This results in an exciting task for us architects and our clients, who conceive a project together with us: We have to distinguish short-lived trends from permanent developments. Until 02|20 (the beginning of the so-called COVID crisis), long-term developments could be tracked over the last 15 years, which applied to most of our projects: A steady influx into cities, a drop in the number of people per household, a reduction in flat sizes and a reduction in the number of rooms. At the same time, underfloor heating became standard and, where possible, every flat was given an outdoor area. As far as location was concerned, the golden rule was: the closer to the underground, the better. The shutdown in April 2020 represents a wide-ranging field test with regard to alternative forms of work, digitalisation, mobility and family stability. For us planners, the task now is to find out which changes from this experiment are just a fleeting trend and which will become permanent. The demand for living space with the opportunity to work undisturbed will grow. One answer could be co-working spaces, which in turn could be a huge opportunity for unused ground floor zones. The desire for open space will bring living outside the city back into focus - an opportunity to breathe new life into smaller cities. Perhaps the relationship between main residence in the city and second home in the countryside will be reversed! The rural communities would thank us for it in terms of their finances! In the city centre, the demand for compact residential units could increase further: The daily commute over long distances and the associated traffic problems could be alleviated if data instead of people commute. Our responsibility here: as trendsetters and planners, we can contribute to these developments!
