As part of the refurbishment of these prestigious central London offices, we supplied and installed the mechanical services which included cooling, heating and ventilation, sanitaryware and DHCW & AGD.Taking into account the location and limited space, the condensers couldn’t be located on the roof and therefore basement located water cooled condensers were utilised. An associated flat type dry cooler was located on the roof and required a crane lift.The services were designed to be sympathetic to the building and its décor and included floor standing fan coil units and associated ductwork & grilles integrated into bookcases and cases.
