76 Southbank
Introducing an upgraded Brutalist icon

Designed by Sir Denys Lasdun and completed in 1983, the IBM Building is a bold presence in the buzzing cultural playground of the South Bank. Working with Stirling Prize winning architects Allford Hall Monaghan Morris, we’ve sensitively refurbished and extended this Grade II listed Brutalist treasure to update it for contemporary office occupiers — and enhance its future.

What we did
Learning from the past
Ensuring 76 Southbank is fit for the present day, and for many years to come, Stirling Prize winning architects AHMM were appointed to lead on design. They undertook deep research into the history and architectural intent of the original building — including the extension elements themselves which were considered by Lasdun during the initial concept design stage.
Building for the future
The update, whilst respecting the heritage and historic fabric of the existing building, delivers highly efficient and flexible commercial office space of the highest sustainable standards. Meanwhile, outside, we’ve improved the building’s relationship to the local conservation area and river frontage.
London’s cultural concrete playground
With landmark institutions like the National Theatre and Royal Festival Hall, Southbank is one of London’s most important cultural and employment hubs. The refurbishment and extension of the neighbouring IBM Building further cements the area’s status as an incomparable destination.
