The apartment is located in a new residential building in Sofia, and its concept emphasizes a seamless transition between spaces through the use of materials, colors, and furniture design. The main living area is unified by a dominant color, which continues across the ceiling and walls, visually expanding the space and creating a sense of continuity and lightness. The accent color flows smoothly through the glass partitions and extends into the bedroom. In the cabinet, the window framing merges into a piece of furniture, a design approach that is repeated in the living room, ensuring both visual and material cohesion between zones. The bathrooms combine accent porcelain tiles with a finishing surface of pozzolan-lime, which continues seamlessly onto the walls and furniture surfaces, creating a refined and cohesive aesthetic.
