New Home Office Headquarters
The redevelopment by Bouyges UK includes
the demolition and removal of the existing building’s
and bomb shelters down to the existing basement slab.
This will be followed by the construction of 55,000m²
of offices for the Home Office and Her Majesty's Prison
Service and 10,000m² of private residences.
The existing buildings at Marsham Street
pose a significant challenge both in their demolition
and in attempts to re-use as much of the building materials
as is possible. The demolition is expected to generate
over 250,000 tonnes of concrete and a range of other
valuable resources including steel, glass, aluminium
and numerous fixtures and fittings. The use of recycled
aggregates will be used in prefabricated components
of the new structure. This practice will be used in
Battle McCarthy's other high-profile projects including
the Elephant and Castle Redevelopment. Throughout the
design process, Battle McCarthy has worked closely with
the Building Research Establishment to develop the potential
of using this as a demonstration project.
A unique environmental solution was
developed for climatic control of internal spaces. This
comprises of multiple zonal heat pumps all sharing energy
across an ‘energy transfer loop’. The system
makes the best possible use of variations in heating/cooling
loads across all buildings. Central chillers are a fraction
of conventional sizes. The transfer loop requires boiler
input during low winter months and otherwise generally
rejects the residual of heat via roof cooling towers
for the rest of the season.
