Park Hill Estate by Lynn and Smith

Park Hill estate, Sheffield, 1963. Part of the Park Hill estate, designed by Jack Lynn and Ivor Smith, who were tutored by the Smithsons – the founders of new brutalism. The estate was famous for its experimental ideas, like walkways in the sky, and that approach was reflected in the playground. Photograph: Arch Press Archive/RIBA.
