Combo Competitions' latest ideas challenge, entitled Hello Nature!, centres on a site located in northern Sweden at the foot of a mountain (Omneberget), sat within an area called the High Coast (Höga Kusten) - which is also a UNESCO World Heritage Site.

The wider question the competition poses is whether or not architecture can encourage involvement with nature. Previous Combo Competitions have included the London Cinema Challenge and Faith! A Place of Worship in London, both of which attracted a number of high quality proposals.
