Purpose: The purpose of this paper is to report the grounded theory empirical validation on key categories within a design-led methodology to envision urban futures. The paper focuses on the editorial products and the design concepts that constitute the heart of the approach. An original elaboration of trend clusters is presented as an exemplification of the outcome of this trend research approach. Although the approach was not created from the viewpoint of tourism and leisure, bibliographic notes on place-making complement it for this journal. Design/methodology/approach: The paper presents empirical findings extracted by the means of the grounded theory, with the purpose to empirically validate two key categories (product and process) of a urban futures methodology. The methodology is an application of High Design, the process in use at Royal Philips BV for two decades. This methodology is contextualized within the constructivist episteme, as defined by the editors of this journal in a separate publication. Bibliographic references to place-making complete the paper. Findings: The following findings are provided: empirical validation of the city.people.light communication platform (qualitative research); empirical validation of the city.people.light workshop practice (qualitative research); and bibliographic descriptions of the design process governing city.people.light and newly developed urban futures trend clusters, at European level, as an exemplification of the program/approach outcome. Research limitations/implications: The paper is structured according to a multi-layered editorial focus. Empirical findings were generated at primary research level in a 2013-2015 grounded theory projected by the author. Furthermore, the author directed the research processes and products that are the object of empirical validation. Newly defined elaborations and a discussion thereof is offered, taking into account contemporary place-making issues. Practical implications: The original design-based methodology is a structured practice in urban futures from applied sciences and corporate innovation viewpoint. In this paper, its key categories are empirically validated through the grounded theory. Additionally, outcome from the original foresight programs is presented and a bibliographic review is provided from the viewpoint of place-making. Social implications: The co-creative methodology herein empirically validated is socio-cultural centered, with a strong drive to coutnerbalance the positivist and engineering corporate mindset through a humanistic concern for people. The framework in terms of place-making takes into account postmodern evolutions of the field. Originality/value: The paper benefits from a unique mix of: epistemic note on tourism, leisure, and the future; original urban futures scenarios and design concepts from a world class corporate innovation program; and the actual empirical core of the grounded theory validation as performed in a dedicated research project. These three separate streams are mutually related.
