TWO MARATONERS HOUSE
Biro Gašperič / Slovenija
The House for Two Marathoners is designed as a space of openness, light and connection with nature. Large panoramic glazing opens views towards the Stična Monastery and the surrounding landscape while flooding the interior with natural daylight. M Sora timber windows with large formats and refined lines create a sense of spaciousness, warmth and a seamless connection between the interior and the outdoors. The architecture combines contemporary aesthetics, natural materials and technical sophistication for comfortable living in close contact with the environment.
