The population in Europe is continuously aging. A declining birth rate combined with a higher life expectancy (women: 83 years; men: 78 years)1) are the main reasons for this development. According to the European Commission, people aged 65+ will represent 30 % of the total population in Europe while they currently represent 20 %2). Besides the increasing challenges in the labour market (the last birth cohorts of baby boomers are retiring within the next few years), we also need to think of attractive and dignified living solutions for seniors. At one point all people must ask themselves how, where and with whom they want to live when they retire. Usually, the answer is quite clear. People want to stay in their apartment or house where – in most cases – they have been living for many years. Nevertheless, many factors can make it challenging for seniors to stay in their familiar environment. Besides the potential need for assistance (with the household, groceries etc.), loneliness – for example, due to divorce or loss of a partner – is a severe issue considered to be a hidden pandemic as per the World Health Organisation.
