The Claridge’s Hotel
The Practice was responsible for designing the complete refurbishment of the mechanical, electrical and public health services to all of the guest rooms, together with the penthouse units in The Claridge’s Hotel.




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 speculative office space is fitted out to a Category A standard and will be British Council of Offices (BCO) Guide to Specification 2019 compliant. The refurbishment has adjusted the temperature control zones to pull them better in line with the BCO recommendations than currently provided.

The development at Thirty High will comprise circa 300,000ft² of primary office led accommodation together with retail and amenity space.

The Adventure Park covers 1.2 acres and is created using sustainably-sourced wood from the Windsor Estate, providing an extensive playground for families to explore together.

Watkins Payne was involved with the Fetter Yard project on 86 Fetter Lane for 5 years and provided the MEP services design and BREEAM assessment.
