We present a modern prefab house with an elegant and minimalist design. A distinctive feature is the illuminated edge of the roof and the front part of the structure. This edge has a decorative, openwork pattern that lets light through, creating a light frame effect, giving the building a modern and futuristic character, especially against the natural surroundings. The front of the house largely consists of glass surfaces – from floor to ceiling – allowing maximum use of natural light and views outside. The interior is open, spacious, with modern, comfortable furniture. The second level has a mezzanine visible through glass windows, suggesting efficient use of interior space. "Peace of Mind" combines modern design with functionality and attention to aesthetics, emphasizing sustainable architecture and efficient space use.
