Back to work page People Of Park Hill. Urban Splash. For over sixty years the Park Hill estate has overlooked the city of Sheffield. It remains one of the largest surviving examples of post-war brutalist architecture in the UK. It’s become one of the region’s most recognisable landmarks and is an integral part of the city’s cultural identity. Following a period of decline and neglect, Park Hill is currently undergoing regeneration by Urban Splash and their partners. The estate is now entering a new phase in its history. The “People of Park Hill” series of portraits celebrates the rich, diverse community who live and work there.
