The City of London Corporation has granted planning permission for two significant office tower developments in the Square Mile, marking a notable expansion of the area’s high-rise cluster. One of these towers, located at 85 Gracechurch Street, underwent crucial design revisions after the discovery of ancient Roman ruins on the site, shedding new light on the city’s rich historical layers.

Originally proposed as a 32-storey tower by Woods Bagot for the Hershten Group, the scheme at 85 Gracechurch Street was revised following archaeological investigations by the Museum of London Archaeology. These investigations uncovered foundations and walls from a 1st-century Roman basilica, featuring materials such as flint, ragstone, and Roman tile. This significant find, part of the civic centre of ancient Londinium, prompted a reduction in the tower's height to 30 storeys to preserve the site. The updated design now integrates a public exhibition space in the basement to permanently display the ruins, alongside enhanced public amenities including a new hall, retail units, event spaces, and a fifth-floor heritage garden that offers views over nearby Leadenhall Market. City planners have welcomed the project, highlighting its potential to rejuvenate the market and celebrate the City’s 2,000-year history, despite opposition from Historic England on heritage grounds.

In parallel, Fletcher Priest has secured approval for a 46-storey office tower at 63 St Mary Axe, another prominent addition to London’s skyscraper skyline. Planning officers have recommended the scheme despite objections from Historic England, which expressed concerns about the tower’s impact on historic views, particularly those of the Tower of London, and on a medieval burial ground located at the site. The City of London’s Planning Applications Sub-Committee unanimously resolved to grant permission for this development, reflecting the ongoing prioritisation of office space expansion in the Square Mile amid efforts to balance heritage conservation.

Together, these developments illustrate the complex interplay between urban growth and heritage preservation in central London. While the towers will bring substantial new office capacity—35,000 square metres planned at Gracechurch Street alone—they also spotlight the challenges faced in integrating modern construction within a historically rich environment. The City Corporation’s planning decisions reflect a nuanced approach that accommodates economic development while endeavouring to protect and showcase key archaeological finds.
