Code Sheffield is an under-construction skyscraper located at the junction of Wellington Street and Rockingham Street in Sheffield, South Yorkshire. Construction commenced in March 2022 as part of the Heart of the City 2 redevelopment of this area of the city centre. With an originally planned height of 117 metres (384 ft) once completed, Code Sheffield would have overtaken both the St Paul's Tower as the tallest building in Sheffield and Altus House in Leeds as the tallest building in Yorkshire. However, due to rising costs the planned height of the building was reduced from 38 to 26 storeys.
