1 Undershaft is a supertall skyscraper planned for the City of London financial district. The scheme is being developed by Aroland Holdings[4] and designed by Eric Parry Architects. It is set to replace the St Helen's tower, and if built will share The Shard's status as the tallest skyscrapers in London and the United Kingdom.

The building is the third design for a skyscraper at 1 Undershaft, replacing two previous proposals designed by architects Avery Associates and Eric Parry themselves respectively. The second proposal, nicknamed 'The Trellis' due to its external cross bracing, was given approval in November 2016, but this design was ultimately discarded in favour of a quad-segmented tower revealed in August 2023.

The substantial changes entailed will result in 1 Undershaft needing to once again apply for planning permission from the City of London Corporation.[5] Construction is planned to take around five years subject to planning, with enabling works starting in 2024, construction work starting in late 2025 after the demolition of St Helen's tower, and completion in 2029.[2][5]
