Tucked away in the Geraneia Mountains of Corinthia, amidst an olive grove of 600 trees, stands a truly unique architectural gem: a triangular house known as The Pythagorean. As its name suggests, the inspiration behind this remarkable structure stems directly from the mathematical brilliance of Pythagoras and his famous theorem—which gave shape to its bold geometric form.
This architectural marvel isn’t just a visual statement. The triangular house blends design innovation with environmental sensitivity, prioritizing both safety and harmony with nature. One of its standout features is the fully retractable glass walls, which blur the boundaries between indoor and outdoor spaces—inviting the surrounding landscape into daily life.
The homeowner, who has embraced a minimalist lifestyle, explains how the home’s simplicity has transformed her way of living:
“I'm getting older, and keeping things simple just makes life easier.”
A Design Rooted in Nature and Geometry
The house was designed by architect Tilemachos Andrianopoulos, after the homeowners—former office workers—chose this serene location to reconnect with nature. The project quickly captured international attention and was even featured in stunning aerial footage on the UpDrones YouTube channel.
But it’s not just the triangular shape that sets this home apart. The design thoughtfully integrates with the landscape. Trees and plants were incorporated into the structure itself, softening the presence of concrete within the natural surroundings. Even the roof is planted with vegetation, helping to naturally cool the house during the hot Greek summers.
Function Meets Philosophy
A particularly distinctive feature is the use of water from an old well in the olive grove. It flows across an exterior wall, creating a calming ambiance with the gentle sound of moving water. Inside, the design remains intentionally minimal. With no interior walls dividing the space, the living room, dining area, and kitchen all flow together seamlessly across the two shorter sides of the triangle—enhancing openness and interaction.
Recognized on the International Stage
The Pythagorean House has received recognition beyond Greece. In 2015, it was nominated for the prestigious European Union Prize for Contemporary Architecture, and in 2016, it won third place in Häuser magazine’s competition for the best home in Europe.
This award-winning triangular residence isn't just an architectural curiosity—it's a modern tribute to ancient ideas, proving that geometry, simplicity, and sustainability can coexist beautifully under one roof.
