The second-floor design for the Nguyena residence continues the theme of refined Swiss minimalism, focusing on elevated privacy and comfort. This level features master and guest suites characterized by integrated wood-slat headboards, custom floating vanities, and expansive windows that frame the surrounding scenery. The palette remains cohesive with warm oak flooring and soft neutral tones, accented by statement lighting and geometric wall art. By balancing sleek cabinetry with organic textures, the second floor serves as a serene sanctuary, completing the home’s transformation into a sophisticated, cohesive, and light-filled modern European masterpiece.
