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.

The Grade II listed 21 St James’ Square building has been refurbished to offer 89,000ft² of high quality office accommodation, for which Watkins Payne supplied building services engineering, vertical transportation engineering, energy consultancy to achieve an BREEAM ‘Very Good’ and EPC B rating.

Nash House is located on the corner of Maddox Street and St George Street in London and was constructed in 1980s. The site is right in front of the Garde I listed Church of St George and stone throw away from famous Handover Square. Currently ground floor is occupied by a retail tenant where the lower ground, 1st floor to 5th floor is office accommodation.
