One New Change

City of London

The One New Change project was a prestige mixed retail and commercial development situated in the heart of London opposite St Paul's Cathedral. The footprint of the development is 10,000m, of which three floors are retail space, leaving the remaining five floors for office use. The building incorporates four intricate slipformed cores and has a central atrium radiating out to New Change, thus facilitating excellent views of the Western facade of St Pauls. The structural element of the building within Byrne Bros.' package, valued at approximately £30 million, and was awarded by Land Securities in autumn 2007.

It is founded on large diameter bore piles containing steel plunge columns

The project had a 3 level basement constructed using top down methodology.

The building is founded on large diameter bore piles containing steel plunge columns.

It is comprised generally of structural steelwork columns monolithically connected to the concrete in situ floor plates up to the 2nd floor. From the 3rd floor to the roof, construction is concrete on metal decking. The building occupies virtually all the 10,000 m2 footprint and thus required extensive coordination with other trades to ensure efficient usage of craneage and storage space which was minimal. A just in time policy for deliveries was essential for successful delivery of the project.
