According to the census data about 70% of Riga’s residents live in large scale housing neighbourhoods built in the time period from 1960s to 1990s. While these neighbourhoods are often characterized with good public transport connections with the city center and variety of services provided in close proximity to homes, the outdoor environment is usually considered to be of poor quality and lacking recreation opportunities. Contrary to masterplanning, temporary urban projects, as developed by Raumlabor Berlin, Atelier d’architecture autogeree or Stalker, appear to play a crucial role in giving a new impulss for inefficiently used, even neglected outdoor spaces in the time of rapid urban growth and changing economical and ecological situation. Temporary urbanism involves variety of actors, also artists, civil society groups, community organizations and charities into the planning and decision making process, and so helps to find alternative solutions to regeneration and development of the outdoor environment (Madanipour, 2017). However, as show recent practices not every temporary project can lead to long-term changes and so positively affect social, ecological or economic situation (Desimini, 2015). Some impact of temporary interventions still remain unclear. This article demonstrates research on introduction of temporary projects in residential areas of other European countries, showing correlation between different actors and their role in the project. Chosen projects are characterized with different types of interventions, scale, participants’ motivation and participatory models, being all realized in the residential areas. Basing on the chosen case studies specific guidelines for temporary urbanism in terms of regeneration of the large scale housing neighbourhoods are proposed.
