Reflected Identity II

Façade of 30 St Mary Axe, also known as the Gherkin, at dusk. The double façade creates a natural ventilation system and giant double glazing effect; air is sandwiched between two layers of glazing and insulates the office space inside. The triangulated perimeter structure is structural and adds to the buildings rigidity. Architect Foster + Partners (2004). Engineer: Arup. London, UK, 2009
