61 Whitehall is the long term home since 1895 of the Royal United Services Institute (RUSI) that needed a complete refurbishment and upgrade to suit its current day needs and operational requirements. The works to the Grade II* listed building included the addition of a new floor, fully refreshed library and function rooms, plus creation of a south facing dome that will be used for multiple different events using electrochromic glazing.
The MEP services were all replaced with a focus on energy efficiency using air source heat pumps, LED lighting and natural ventilation where possible. The services were designed to suit the bespoke fit out requirements of RUSI all integrated into the architectural features within the listed building.
