24 King William Street, London – Projects

At 24 King William Street, we worked with Ben Adams Architects to transform a dated and under-utilised 1980s steel-framed office building into a modern mixed-use space that responds to the urban and historical context.

The refurbishment included a new three-storey mansard as well as a brand-new façade and interior, opening up the ground level retail space. The new upper storeys include two additional office floors and an open plant deck, which adds substantial square footage to the site.

By targeting surveys and focusing strengthening works on key components, rather than entire structural systems, Elliott Wood demonstrated that the additional floors could be accommodated onto the existing structure without needing to undertake costly strengthening works to the existing frames or foundation, and to maintain occupied rental units on the lower floors.

Our targeted and non-invasive approach resulted in a scheme that minimised embodied carbon by removing the need for foundation works and limiting the additional steelwork strengthening required, which in some areas consisted of simple bolt upgrades.

The project has reinvented 24 King William Street for 21st century tenants and their needs, while respecting the heritage of its immediate context and protected views along the historic London Bridge area.
