30 Second Briefing
Bovis Construction (Europe) has secured a £200m PCSA to refurbish and extend 10 Paternoster Square, home of the London Stock Exchange, including a new glass atrium making the daily market opening and closing ceremonies visible from the public realm. The scheme adds roof extensions, an events pavilion and multiple terraces and balconies with views over St Paul’s Cathedral, while retaining more than 95% of the existing structural frame and façade in line with circular economy principles. The project targets BREEAM Excellent and NABERS 5* ratings, with completion due in Q4 2028.
Technical Brief
- £200m PCSA covers refurbishment, extension and full fit-out of 10 Paternoster Square.
- Pre-construction services with Bovis Construction (Europe) commence next month, defining phasing and buildability in a live financial district.
- Oxford Properties and Hines act as joint developers, coordinating commercial, planning and heritage constraints around St Paul’s.
- Building was originally completed by Bovis in 2003, giving the contractor legacy knowledge of existing structure and services.
- Reconfiguration includes a new glass atrium forming the visible ceremonial core of London Stock Exchange operations.
- Additional roof extensions, events pavilion and multiple terraces require complex rooftop structural strengthening and waterproofing interfaces.
- Retention of more than 95% of the structural frame and façade drives heavy reliance on intrusive surveys and connection detailing.
- Completion is programmed for Q4 2028, implying a multi-year staged construction sequence around ongoing City operations.
Our Take
Bovis Construction (Europe)’s recent push to add a Birmingham base and a dedicated UK health lead suggests the £200m 10 Paternoster Square job will sit alongside, rather than define, a broader multi-sector workload, which can help resource smoothing on a long programme running to 2028.
Retaining 95% of the structural frame and façade at 10 Paternoster Square aligns Bovis with the more complex end of refurbishment work in our infrastructure coverage, similar in risk profile (though not in heritage status) to its Manchester Grade I-listed town hall scheme, where scope and cost control have been challenging.
Targeting both BREEAM Excellent and a 5-star NABERS rating in the City of London places this Oxford Properties/Hines asset in the top tier of sustainability-driven office refurbishments in our database, which is increasingly a prerequisite for blue-chip financial tenants around St Paul’s and the wider Square Mile.
