1 Undershaft

A detail planning application was submitted to the City of London January 2016 for the 73-storey development at 1 Undershaft in the City of London. At 289.94m tall, it will rise to a height of 304.94m AOD (Above Ordnance Datum), crowning the new cluster of planned skyscrapers in the square mile.

Whilst this permission could be progressed, given the notable increases in the desire for more wellbeing-led office space, and the City of London Corporation’s new ‘Destination City’ initiative, the development team have taken the opportunity to reconsider their approach. The new proposals deliver a more wellbeing-led commercial space, with high-quality external spaces, public opens spaces, improved sustainability and a cultural and creative offer.

The new proposals will form a new landmark tall building on a site allocated in the City Plan for the tallest building in the cluster, offering world-class public spaces. Public consultations are underway with Kanda. More information can be found on the consultation website:

“The new scheme will still be the tallest in the city cluster and retains the upper floors for educational and public access through a collaboration with the Museum of London. The revised proposals will enable us to deliver a more sustainable building with enhanced urban greening.”
