Structural Steel Design Awards: One Bartholomew

Published 30th August 2022

One Bartholomew, the exceptional 223,000 sq ft Grade A office building in London’s Barts Square, was Commended at the 2020 Structural Steel Design Awards (SSDA).

Winning projects are celebrated as examples of structural and architectural design that withhold the highest standards across the UK and overseas. Ranging from health and education to retail and residential, each building showcases the flexibility and versatility of steel in a number of different and varying applications.

Designed by Sheppard Robson architects, One Bartholomew was completed as part of Helical’s exceptional new 2.3-acre mixed-use development in the heart of London. The wider Barts Square site was formerly occupied by St Bartholomew’s Hospital before being transformed into 236 contemporary apartments and penthouses, 258,000 sq ft of commercial offices, and 20,000 sq ft of complimentary retail, restaurant and café facilities across 13 buildings, of which One Bartholomew is the tallest.

The building has been designed with elegant column-free “glass to glass” corners with the largest of them involving a dramatic 9 m cantilevering corner. This substantial and challenging cantilever corner was achieved through the careful arrangement of structures at the level of the cantilever and all floors above. Control of structural deflection at the cladding interface was carefully considered and was further complicated by the necessary integration of building services in the areas of the cantilever.

The judges’ stated: “The project showcases how steel can deliver a highly flexible long-span commercial building within an urban context. The nine-metre corner cantilever of the upper floors over the entrance enhances the presence of the building in the public realm. The progressive procurement approach meant that the steelwork contractors were appointed early, supporting the design team to maximise efficiency of design and fabrication.”
