Set along the Aegean coastline on Kythnos Island, The Outdoor House by Sigurd Larsen Design & Architecture offers a pared-back approach to holiday living. Here, simplicity, climate and landscape shape the experience. Designed as a guest house for the nearby Piperi House, the structure occupies a stone terrace above the sea. It opens with a discreet garden-style entrance that leads to a space defined not by walls but by views. The heart of the house is an expansive pergola that shades and defines the outdoor space. Crafted to filter the Greek sun while welcoming the island’s cooling breeze, it creates a naturally temperate environment for rest, cooking, and socialising. A movable dining table and fixed stone plinths offer flexibility, allowing guests to follow the shade or sit quietly with a view. Outdoor living is the priority. An open kitchen and a freestanding shower complete the essentials, encouraging a full embrace of the Mediterranean climate. For cooler nights or sudden weather shifts, a compact enclosed room provides basic shelter—a bed, a workspace, a toilet. It’s the only heated area, marking the minimal threshold between outside and in. Materially, the house blends into its setting. Stone walls and built-in furniture mirror the rocky Cycladic terrain, dissolving boundaries between architecture and nature. As visitors move through the space, the landscape unfolds, blurring lines between the constructed and the untouched. With The Outdoor House, Sigurd Larsen proposes a way of living that’s both contemporary and ancient: rooted in climate, adapted to place, and elegantly stripped to the essentials.
