Healthy lifestyles in our ever increasing urban environments are not only a requisite of public health policies, but also recommended by the United Nation (New Urban Agenda, 2017). This publication is one of the results of the ongoing Healthy Happy Cities in Tropical Environment project, based on problem-solving and gamification approaches, funded by the French-Australian Network, the School of Architecture of La Reunion (France) and Griffith University. The aim of the project is to develop a platform and tools for key stakeholders in design, tourism and health, in order to better integrate urban design in tropical environments to facilitate happy experiences in our cities. For this creative output, the research investigated the characteristics of tropical architecture and urban design, delimiting preconceived ideas and concepts, employing a gaming approach. The research significance is evidenced by the continuous collaborations and activities between the key partners of this project, recently supported by Un-Habitat (Urban Thinker Campus, ENSAMR (France) November 2019 https://www.worldurbancampaign.org/urban-thinkers-campus ) The transferability of the project across the tropical regions is expected to open new ways in transforming the cities in positive liveable places, both physically and mentally.
