Siemens plans to invest £30m ($43.4m) in a new landmark building in east London, which will be the flagship project of a new Green Enterprise District.
The Green Enterprise District's plan will stretch across east London and is designed to position the UK's capital as a global leader of the low-carbon economy.
A consortium, comprising Pringle Brandon and Wilkinson Eyre Architects, will deliver the 7,002m² pavilion.
The three-storey building, which features a 300-seat exhibition and conference centre, will employ sustainable technologies in its design and construction.
The Siemens pavilion will be built on land owned by the London Development Agency and Newham Borough Council. It is hoped that it will help resuscitate the deprived parts of the capital.
The scheme is expected to be complete in 2012.
