 Late 20th century and early 21st century Finland has witnessed greater consolidation of the greater capital region, Helsinki-Espoo-Vantaa.Helsinki, unable to expand outwards due to being hemmed in to the coastline by the neighbouring cities (formerly rural counties) of Espoo and Vantaa, has adopted planning policies of increased urban densification, also argued for under a policy of sustainable development and "green building", but also de-industrialisation, that is, moving industrial concerns away from the shorelines in proximity to the city centre, which are then redeveloped for generally up-market housing.A good example is the shoreline-facing housing development on Katajanokka, Helsinki, by Nurmela-Raimoranta-Tasa architects (2006).
