Steel and glass
With only five or six hours of light in the Finnish winter, this web of steel and glass lets as much of it as possible into the Espoo HQ.
Huge interior, concave walls
This is the curved wall of offices that benefit from the webbed glass ceiling. This shot gives a sense of how huge the building is. The concaved wall of offices overlooks the main thoroughfare in the newer of the two parts to HQ.
Nokia CEO Stephen Elop's office is on one of the top levels of this section of the building.
Nokia HQ was built between 1996 and 1997, with Elop joining the company as chief exec in 2010 - the first non-Finn to hold the job.
