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. This competition is looking for "structures that celebrate nature", which also involve elements of "both education and recreation, or - if you prefer - business and pleasure." 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.
