Overview

• Engineers suspended the 14th‑century All Hallows Staining tower on 45‑foot stilts above a 60,000 sq ft excavation after removing more than 125,000 tonnes of earth.
• The 36‑storey, roughly £1 billion project led by Axa IM Alts will deliver about 650,000 sq ft of offices with ground‑floor retail and a public roof experience.
• Crews installed stilts and then built a raft foundation in sections beneath the tower, which is being monitored continuously during basement construction.
• The plan includes reinstating Lambe’s Chapel Crypt and creating a new green public space with public access to both listed structures.
• Historic Royal Palaces and Kuwait’s sovereign wealth fund contested the scheme over protected views and light earlier this year, but works have advanced to the current milestone.
