In this age of rapid urbanisation and the continuous pressure for new developments, cities are facing more and more complex issues. Lack of public money leads central Governments to cut funding and privatise public services and spaces. This affects the ability to deliver civic and community services and leads to a state of “austerity urbanism” (Tonkiss, 2013).The growing trend of privatisation was expressed in 2018 when the railway network sold its railway arches to a private operator (“Network Rail sells railway arches”, 2018). This privatisation of the arches and local authorities cuts led to the appearance of new uses type under the railway arches. Most of them are commercial and retail uses that aim to maximise private interests and financial profit. Those types of uses do not necessarily enhance the needs of local communities; it increases rent prices, pushes out the current business, accelerates gentrification and displacement.This project aims to explore the use of the Commons (community-managed resources) and bottom-up approaches to provide a new community civic infrastructure under the railway arches that create social and economic value for the area and promotes a socially inclusive regeneration process. The project first reviews the current trends regarding adaptation and uses under the railway arches, followed by a theoretical review about a partnership, bottom-up approaches and civic engagement in addition to value creation and value capture. The theoretical aspects will be explored in the literature review and used to analyse case-studies from London and around the world. Those will shape the proposed toolkit, which then will be applied to a chosen site.
