As simple and navigable as the Latvian landscape, with its long horizon and clear skies, draped gently with myriad unique cloud formations dotting one's path to Riga. We explored the idea of the modern airport as the conceptual and literal horizon threshold where the "sky" meets "land". We put this terminal squarely in a cloud, using a double-skinned ETFE membrane system, The cloud serves serves as temperature and lighting control, navigation system, signage infrastructure, and most visible: a unique travel travel; experience that promises to make Riga Airport more memorable.
