Key Challenges

  • Providing a high serviced building within the existing fabric, whilst ensuring luxury finishes throughout.
  • Forming a design to fall in line with the combination of planning restrictions, listed building consent, the freeholder’s (Grosvenor Estates) licence to alter and party wall matters.

27 Berkeley Square, London

Client: Time Products
Architect: March & White

The refurbishment and restoration of a 6 storey, grade II listed Victorian Building in Mayfair, London. The building will form the London headquarters of Time Products’ Luxury Watch division incorporating offices, display areas and ancillary spaces. The works shall restore elements of significant heritage value and provide a refurbishment in keeping with the building’s stature, with a high quality of finishes. 

Mechanical Systems Solution

Mechanical ventilation has been provided throughout by local heat recovery units, to keep ductwork distribution sizes to a minimum and prevent the requirement of external air handling plant to serve the building. Utilising mechanical ventilation allows the windows to be kept closed which was key in providing suitable acoustic levels within the office spaces. Heating and cooling is provided by a number of variable refrigerant flow systems. Low height external condensers were selected to prevent their visibility from the surrounding areas, particularly Berkeley Square itself. Internal fan coil units are typically housed within bespoke joinery pieces.

Electrical Systems Solution

Where possible the electrical infrastructure was re-used, following a refurbishment in the last 10 years, to save capital expenditure and to ease installation through the minimal services voids and risers. We worked with a specialist lighting consultant to produce a coordinated, high quality lighting design throughout the whole building, including the detailing of the display areas. Due to the high value of the building’s contents GDM worked closely with a security specialist to ensure the insurance requirements of the Client were exceeded.
