Prompt für den Bildgenerator: "Create a set of four interior floor plan sketches for a future urban apartment designed for 1-2 people. The layout should be similar in overall shape but each variant should be distinctly different in terms of spatial organization, style, and functional zones. The apartments should be functional, cozy, not too large, and reflect innovative, utopian living concepts. Each floor plan should emphasize efficient use of space, flexibility, and a harmonious flow. The four variants should differ significantly in layout style:** Open-space concept with multi-functional zones, minimal walls, emphasizing shared living and adaptable furniture. Private zones with separate sleeping and working areas, integrated with natural elements and biophilic design. Vertical layering with split levels, mezzanines, and dynamic spatial separation for different functions. Community-oriented layout with shared spaces, communal kitchen, garden access, and flexible private units. Style: Technical blueprint sketch with clear lines, black-white color, and a focus on spatial relationships. Aspect ratio 4:3." Mehr sehen
