In the 21st century, Slough has seen major redevelopment of the town centre. Old buildings are being replaced with new offices and shopping complexes. Tesco has replaced an existing superstore with a larger Tesco Extra. The Heart of Slough Project is a plan for the large-scale redevelopment of the town centre as a focus and cultural quarter for the creative media, information and communications industries. It will create a mixed-use complex, multi-functional buildings, visual landmarks and a public space in the Thames Valley. Recommendations for the £400 million project have been approved, and planning approval was given by Slough Borough Council's planning committee on 9 July 2009. Work began in 2010 for completion in 2018.
