A set of three isometric architectural drawings from a top-down perspective, showcasing a minimalistic, minimalist interior design with a plain white background. the image also shows three distinct sections of a single-story building, each with its own distinct design. the first section, on the top left, is a simple, rectangular structure with a flat roof and a rectangular base, while the second section, in the middle, is an open-frame structure with multiple windows and a door, and the third section is a smaller rectangular structure. all three sections are drawn in a straight line drawing style, with no visible details or shading, and are arranged in a way that creates a sense of depth and dimensionality.
