Project Management
One of the tallest buildings to ever be demolished in the City into it's tallest building standing at 74 storeys, 310 meters tall comprising of 3 stacked buildings, the development will become the joint tallest tower in Europe, providing approximately 154,000 square meters of commercial space. Turner International's UK branch, Real PM, is working on behalf of the project's Development Manager, Stanhope, providing project management, contract administration and programming support for the soft strip, asbestos removal and complex hard demolition works to St Helen's Tower.
Hard demolition of the existing 118-metre tower began in early 2026, making this one of the tallest buildings ever to be demolished in the City of London. The demolition is particularly technically challenging due to the building's unusual top-hung structure which means its floors are suspended from steelwork cantilever systems one at mid-height and one at the top of the building. These are supported on the central core, meaning gravity loads travel upwards, before being carried down to the foundation.
Once complete, One London will transform the City's historic financial district with a new 74 storey tower standing 310 meters tall. Comprising three stacked buildings, the development will become the tallest tower in the City of London, providing approximately 154,000 square meters of commercial space.
The scheme will deliver an impressive range of public amenities, including Europe's highest publicly accessible viewing gallery at the top of the tower and a free public garden on the 11th floor, offering views of St Paul's Cathedral and 30 St Mary Axe, better known as The Gherkin. The development will also incorporate a world-leading educational space curated by London Museum. Real PM is also involved in delivering the London Museum development, creating a further connection between the two projects.
