A Strategic Move to the City Core

Jane Street is currently in advanced negotiations to occupy more than half of the 870,000 square foot redevelopment at 10 Bishops Square. The property, situated adjacent to Liverpool Street station and Spitalfields Market, is owned by a high profile partnership between the Hong Kong Monetary Authority (HKMA) and JPMorgan Global Alternatives. The firm plans to initially lease 450,000 square feet with an option for future expansion, effectively doubling its current 230,000 square foot footprint at Devonshire Square.

Capitalizing on Prime Redevelopment Timing

The move is timed to align with the expiration of Jane Street’s current lease in 2032, with the new 10 Bishops Square scheme slated for completion in 2030. The site was previously home to the law firm Allen & Overy, which is preparing to vacate for British Land and GIC’s 2 Broadgate next year. By securing this space now, Jane Street has outmaneuvered other potential tenants who were eyeing prime City assets like 75 London Wall and the Dovetail Building, ensuring they anchor one of the most significant architectural updates in the Liverpool Street submarket.

Strategic Rationale and Market Impact

For JPMorgan and the HKMA, the deal cements their status as leading developers in the current London office cycle. Following JPMorgan’s successful 400,000 square foot pre-lease of 65 Gresham Street to Squarepoint Asset Management last year, this transaction further validates the demand for "super-prime" office space. The redevelopment’s focus on modern amenities—including 70,000 square feet of outdoor terraces—is specifically designed to attract high growth financial and tech firms that use premium real estate as a tool for talent recruitment and retention.
