The interior design project of a single-family home is based on the use of natural materials such as bleached oak wood, Bianco Carrara marble, and herringbone Hungarian parquet to create open and bright living spaces within the existing building. Bleached oak wood has been used in the project to create a warm and cozy atmosphere throughout the house. This material has been applied both on the floor and on the walls, adding lightness and natural beauty to the space. Bianco Carrara marble has been used in the project to emphasize the elegance and classic style of the decor. Applied in the kitchen, bathrooms, and other spaces, it creates a unique atmosphere and distinctive character for the interiors. The living spaces are bright and spacious, with green accents that create an interesting atmosphere and introduce a natural character to the space. Subtle neon lights add originality and modernity to the decor while maintaining a timeless character, combining elegance and authenticity.
