If you’ve been aching for a peaceful escape that’s both eco and modern, we couldn’t think of a more stunning place to sit back and relax than Casas na Areia in Comporta, Portugal. Designed by architects Aires Mateus, this gorgeous retreat takes old masonry buildings and turns them into new, contemporary structures set upon the sand. Creating a delicate balance between the natural landscape and modern architecture, Aires Mateus’ design is able to evoke a poetic visual and visceral experience from its inhabitants.
