Global Holcim Awards competition announces winners for 2015

The winners of the 4th Global Holcim Awards for Sustainable Construction have been decided – the trophies and USD 350,000 prize money go to projects in Colombia, Sri Lanka and the USA. All three prizes recognize architectural interventions that deliver tangible benefits to local communities: Turning a decommissioned water reservoir into a park in Medellín, rebuilding social fabric through a community library in Ambepussa following Sri Lanka’s civil war, and creating public zones and flood-protection for the island of Manhattan.
