La Maison en Petits Cubes

In a world where rising sea levels have submerged the landscape, an elderly man lives alone in a house that grows vertically. To stay above the water, he must continually build new rooms on top of the old ones. When he accidentally drops his favorite pipe into the depths of his home, he uses diving equipment to retrieve it. As he descends through the flooded floors, each room triggers memories of his past and the time he spent with his family.
