EDGE London Bridge, an office building located south of London Bridge Station, has recently completed its main structure construction. The project employs a hybrid structural system of steel, concrete, and timber. Of the approximately 1,300 ton of steel structure used, 23 ton consist of recycled steel. The ‘Play Zone’ on the eastern side of the building innovatively uses steel beams to support cross-laminated timber (CLT) floors, making it the tallest building in the UK to adopt this system.
London, UK – As sustainable architectural principles gain momentum, EDGE London Bridge has drawn industry attention for its distinctive hybrid structural design. Standing 27 storeys high near the transport hub of London Bridge Station, the building integrates steel, concrete, and cross-laminated timber (CLT) in its structural system. According to the project team, around 1,300 tonnes of steel components—primarily plate girders and box-section members—are utilised throughout the project, with roughly 23 tonnes sourced from recycled steel, demonstrating the application of a circular economy in high-rise construction.
A key design highlight is the ‘Play Zone’ on the building’s eastern elevation, which features steel beams supporting CLT floor slabs. This design not only reduces the structural self-weight but also provides future tenants with exceptional spatial flexibility for renovation: floor slabs can be dismantled and removed to facilitate the addition of staircases or the creation of atrium spaces. The project team states that the building is recognised as the tallest in the UK to implement a steel/CLT floor system, offering a new technical reference for the application of hybrid structures in high-rise office developments.
