Alise Ārgale Re-imagining Riga through its Modernist Estates: Repositioning the Suburban Periphery within the City Scale Housing and Urbanism Director: Jorge Fiori, Hugo Hinsley The thesis focuses on mass housing projects built on the periphery of Eastern European cities. Although these neighbourhoods were built from prefabricated systems and have a poor range of urban activities, they hold specific and rare urban qualities. In Riga the neighbourhoods comprise 40 per cent of residential units, making their regeneration significant to the entire city. This thesis proposes how Riga could re-imagine itself by supporting the knowledge economy and taking advantage of Rail Baltica and the ‘Northern Corridor’ to create new nodes and to regenerate existing residential areas.
