Interior Services Group (ISG) is set to start work on the £27m project to reclad the 13-storey East Wing building on the St Thomas’ Hospital site in central London, UK.
Recladding of the building is expected to improve the environmental performance, upgrade facilities for patients and staff, and improve the aesthetics of the structure.
ISG along with Hopkins Architects were chosen through a RIBA competition in 2010 to reclad the building, which is located opposite the Houses of Parliament.
The project’s clients include the Guy’s and St Thomas’ NHS Foundation Trust.
Both the firms are working with the UK-based engineering practice Arup, which is managing the structural, MEP, facade, fire and acoustic engineering services for the project.
The recladding project involves the addition of a new glazed external envelope that creates two new triangular atria.
ISG said Hopkins’ design will solve the historic water penetration problems that have blighted the 1960s structure while providing additional patient lift capacity in the new atrium above the building’s northern courtyard.
Sustainable features planned to be added during the project include a range of passive controls, which will maintain ambient temperatures within the building.
The atria roofs will be built from ETFE cushions in a diamond configuration to shade direct sunlight from the south, while permitting indirect light from the north to illuminate the internal space.
ISG said new steelwork, hung from the roof, will support single glazing on the western facade, with aluminium ventilation louvers at the top and bottom of each panel to naturally ventilate the buffer zone between the existing and new envelope.
New solar shading panels will reduce solar gain and provide views across the River Thames to the House of Parliament.
The East Wing building currently features cardiology services, two intensive care units and admission wards.
The facility has a 200 bed capacity, clinical suites and offices, teaching facilities, ancillary plant and storage areas.
