Built in 1926, 20 St James Street, SW1A with its original Portland stone façade is a prestige building.  Situated just a block away from The Ritz, and Fortnum and Mason, it occupies a prime location in Central London.

Combining a ground floor art gallery with restaurant and private entrance, the building also houses high specification and penthouse office accommodation.

MJL contracted SCI to provide BMS design, installation, controls and commissioning for this Art Deco building in the heart of Piccadilly.

SCI delivered a comprehensive Retrofit package at 20 St James Street, which included the provision of a complete automatic controls installation. Supply, install, test and commission of complete dry riser and a ‘water mist’ fire suppression system was also included.  Installation, testing and commissioning of the mechanical supply and extract ventilation systems was combined with heating and cooling mechanical systems. Fresh air is provided via a heat recovery ventilation system, while the office heating and cooling is handled by air source heat pumps.

The system uses Trend controllers (such as TONN and IQ4E32 ) which are integrated with Flaktwood packaged Air Handling Units from Nuaire and JJ Fox to provide VRF air conditioning. Fan Coil Units (FCUs) were concealed in the ceilings to maintain the sleek style of the building interior.

SCI completed the works in 2018 after a 10-month project with a cost of £124,000. The “topping out” ceremony was in May 2017, and the building went on to achieve  BREEAM ‘Very Good’ and EPC B rating.
