Apartment No. 85 is a minimalist apartment located in Beijing, China, designed by The Box Design. This residence transcended conventional design styles, aligning instead with the unique temperament and lifestyle of its owner. The aim was to create a space that was both comfortable and aesthetically pleasing. The apartment featured a striking interplay of black and white, infusing the space with a distinct personality. This minimalist palette enhanced the brightness and openness of the interiors. Subtle accents of cave stone and metal introduced natural textures, adding a serene warmth to the living environment. Architecturally, the apartment was divided into several interconnected volumes, utilizing geometric art techniques to eliminate spatial constraints. This approach allowed for a natural presentation of light, shadow, and form, contributing to the overall sense of tranquility and openness. The design emphasized the inherent structure of the space and the expressive potential of the materials used. By avoiding excessive ornamentation, the project achieved a sophisticated yet understated elegance. The careful selection of materials and thoughtful spatial organization resulted in a harmonious living space that reflected the serene and refined lifestyle of its inhabitants.
