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

Watkins Payne was commissioned to design a Cat A fit-out refurbishment across the existing 11,800sq.ft building. The ground floor was completely redeveloped with a new office entrance lobby and 1,300sq.ft new retail space.

A wealth of experience in exposed services projects has enabled Watkins Payne to provide the highest level specification for the refurbishment of over 50,000ft² of office space at 101 New Cavendish Street in London.

The building at 10 New Burlington Street has been redeveloped to offer 172,000ft² of high quality office and retail accommodation, for which Watkins Payne supplied building services engineering, vertical transportation engineering and energy consultancy to achieve an EPC B rating. We also supplied BREEAM services and achieved a BREEAM Excellent rating for the development.

The building Africa House along Kingsway near Holborn Station has been refurbished to offer 119,297ft² of high quality office accommodation, for which Watkins Payne supplied building services engineering, vertical transportation engineering, BREEAM duties and energy consultancy to achieve an EPC C rating.
