Gateway House, Manchester

Gateway House in Manchester, England, is a modernist office block above a row of shops designed by Richard Seifert & Partners and completed in 1969. It replaced a row of 19th-century railway warehouses on the approach to Manchester Piccadilly station. The building, which differed from much of Seifert's contemporary work in that it departed from the bare concrete brutalist style which had become his trademark, was nicknamed the "lazy S" and was reputedly designed as a doodle.
