The winners of the 4th Global Holcim Awards for Sustainable Construction have been decided, with trophies and US$350,000 prize money going 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.
