CHALLENGE
The project replaced the bomb-damaged, Grade II* listed Baltic Exchange, sparking debate over rebuilding it or pursuing a new architectural direction. The challenge: define a new building that could respond to the loss while fitting within the City of London’s historic context. In short: how to balance heritage, design ambition, and a changing skyline?
SOLUTION
We supported the project by bringing together technical expertise and strategic insights on urban form and heritage. We assessed the condition of the existing fabric and advised on the suitable height and massing of the new building. We also introduced the concept of a concentric building set within a square piazza, offering an alternative to reinstating historic street lines through a podium structure.
With the team, we helped preserve the integrity of the diagrid structure during value engineering. We also prepared the Environmental Statement’s townscape assessment, setting a benchmark for UK tall building assessments.
RESULTS
Historic England accepted that high-quality contemporary design could justify the loss of damaged heritage assets in this instance. The project became one of London’s most recognisable buildings, showing how thoughtful design can both respect and redefine a historic city.
