Millennium Bridge House – London
Millennium Bridge House ORMS Architecture Design has secured planning permission for a 20,000m2 office on a landmark site on the north bank of the River Thames. The £35 million project will transform the existing Millennium Bridge House, which connects St Pauls Cathedral with the Tate Modern, into a mixed use building with a large rooftop garden and new cladding to the main facades, making a positive contribution to the St Pauls viewing corridor.
The refurbishment will reinvigorate the existing building to attract the best possible calibre of end user and will provide 17,450 m2 of office space and a new large roof terrace with significant views south across the Thames. The project will also introduce restaurant and café facilities alongside Peters Hill and Pauls Walk to offer an active frontage and provide a gateway to the City.
Hadene was contracted to undertake the update of the existing services at a value of over £200,000 for updating the cooling towers (water side), replacement of the heating burners, boosters, and pressurisation system on the main roof. This involved out of hours operation, as all equipment had to be transported within the building to the roof plant room, as cranes were not an option due to local works. The method of the works did not affect the operation of the building, as careful planning and methodical attention to detail was a key element to its success.
New tanks were fitted in the basement, with a temporary tank to maintain the building during the changeover. New coldwater boosters were fitted, hot water generators and associated pumps and valves. During this time, again no major disruption affected the operation of the building.
All pumps and bellows were replaced for the heating system, including strainers and valves, so the building would have a long term benefit from replacement equipment for operation and isolation.
