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.
Saffron House was refurbished to provide 38,000ft² of high quality office accommodation. Watkins Payne supplied building services engineering which saw the 1st, 2nd and the 3rd floor including the ground floor reception of Saffron House converted into open plan office areas and reception.
The building has been meticulously refurbished to incorporate a range of sustainable features, targeting BREEAM Excellent and EPC A ratings.
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.
