Best living concepts for elderly homeowners: combining a stated choice experiment with architectural design Ioulia V. Ossokina1   · Theo A. Arentze1 · Dick van Gameren2 · Dirk van den Heuvel2 Received: 9 October 2018 / Accepted: 2 November 2019 © The Author(s) 2019

Abstract In this paper we combine the insights from social sciences and architecture to design best living concepts for a specific target group, elderly homeowners. We perform a stated choice experiment to study residential preferences of this group and translate the results into an architectural design of senior-friendly housing. This methodological approach is novel to the literature. We derive the willingness-to-pay for different residential attributes and show how these attributes can be traded off against each other to create best living concepts. We discuss how these living concepts can be translated into customized architectural design while making use of standard architectural elements.

1 Introduction In various countries, the demand for senior dwellings is expected to rise. Yearly housing mobility rates of European elderly lie between 1 and 5%, amounting to an annual flow of more than 1 million people changing house (Tatsiramos 2006; Gobillon and Wolff 2011; Abramsson and Andersson 2012).1 The absolute number is large and will be growing in the future because the proportion of 65+ citizens in the population increases sharply, in Europe from 20% in 2015 to the expected 25% in 2040 (Eurostat 2017).2 Also, various governments currently make arrangements to stimulate the elderly to live independently at home for as long as possible (Mosca et al. 2017). Such policies may increase the motivation of people entering the third age to move to another home which will better suit their needs as they become older and in need of help. Despite the relevance of the subject and the existence of research on housing priorities of the seniors, not much is known yet about how to translate these preferences into practical living concepts and architectural design. This paper develops and applies a novel methodology to design best living concepts for the elderly, based on the research in their residential preferences and architectural design principles. With ‘best living concepts’ we mean here practically and architecturally feasible combinations of dwelling, building and location attributes that are highly valued by the target group. Our methodology combines insights from two disciplines: social sciences and ar
