anders berensson architects has designed the modular zartmann house on a remote island without roads in the stockholm archipelago, built by helicoptering building kits to the site. instead of one big volume, the summer residence comprises four smaller ones that sit on two separate rocks, and are connected by a deck and a bridge. together, the four volumes, which contain the main house, a sauna, and a guest house, define a promenade among the rocks, walls, windswept trees, and terraces. all images courtesy of anders berensson architects
