This is an interior design case of a residential house. Considering that the base is near the river bank, the designer brilliantly reserved large-scale windows and combined them with the high-ceilinged mezzanine design so that the residents inside could also have a clear view of the river bank outside. Moreover, the primary spatial focus is the white American line panel favored by the female homeowner. Besides, the elegant light-colored marble tile harmonizes with the outdoor natural landscape creating a refined, elegant, and natural living environment. At the entryway, the designer cleverly combines the wall and the storage cabinet into one, satisfying the residents' storage needs and achieving the effect of spatial partition. Upstairs, the shared living is designed with American white paint and the line panel, with the unique texture of glossy marble tiles, showing the elegant and grand tone of the space. In addition, dark gray sofas and blue leather chairs are placed to balance the color scheme, making the space look harmonious and comfortable. In the mezzanine space, the designer set up cabinets with a sense of storage and penetration so that the layout can be adjusted according to the needs of the residents, giving a more diverse and flexible use of performance. Moving slowly to the master bedroom, one will notice the design of the linear panel is continued so that the shared and private areas harmonize with each other. On the other hand, warm milk tea and gray tones are used as the main color scheme of the bedroom, delivering a comfortable and pleasant vibe to give the residents a relaxed and excellent sleeping quality. Also, the designer uses concealed door design to make the whole space as simple and spacious as possible. Entering the dressing room, one will realize that the white cabinet, glass doors, and metal handles create an elegant and luxurious texture.
