A 3d rendering of a modern, minimalist interior space with a concrete staircase in the center. the staircase is made of concrete and has a sleek, modern design. The walls are painted white and the floor is tiled in a light grey color. on the left side of the image, there is a large black square framed on the wall, adding a touch of contrast to the otherwise monochromatic space. two potted plants sit on the steps of the staircase, one with green leaves and the other with white flowers. the overall atmosphere of the space is bright and airy, with a sense of calmness and tranquility.
