Seal House
Watkins Payne carried out the Independent Design Review role for Seal House, a commercial office development, located in central London.




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.

Watkins Payne carried out the Independent Design Review role for Seal House, a commercial office development, located in central London.

The building has been transformed to provide a 133 bedroom hotel including car and cycle parking on site.

The mixed use development comprises two office buildings totalling 530,000ft² of high quality office accommodation together with a 162 unit residential scheme consisting of a 26 storey private apartment tower and affordable housing building. The scheme also includes retail units and a community arts facility. 10 Brock Street is the larger of the office buildings and Watkins Payne supplied building services engineering, vertical transportation engineering, BREEAM duties and energy consultancy to achieve BREEAM ‘Excellent’ and an EPC B rating.
