This angular rural house in Greece by Athens studio Tense Architecture Network has over half of its concrete body buried beneath the ground. 'House in Sikamino' has a 60-metre-long and narrow shape with angular edges that thrust out into the sloping topography, creating a partially submerged upper floor and a completely buried lower level. 'The composition seeks to vigorously merge the residence with its elongated site', explain the architects. Grass covers the roof to create an artificial hill over the top of the house, intended to evoke the shapes of the Euboea mountains in the distance. Residents use the ground for planting herbs. Glass walls bring daylight in along any exposed edges and open out to wooden terraces.
