Home Plan - How it would look
Prompt:
Split composition image, left and right halves clearly divided.
Left Half:
Highly detailed architectural floor plan illustration in a modern minimalist style, matching the attached reference. Top-down view residential layout with labeled spaces including living room, dining area, open kitchen, bedrooms, foyer, verandah, bay windows, and circulation paths. Neutral beige and warm gray color palette, clean linework, soft shadows, subtle textures, interior-design presentation style. Editorial architectural visualization, flat-lay blueprint aesthetic with furniture placement visible.
Right Half:
Ultra-realistic interior photograph of the living room shown in the left-side floor plan. The living room is fully furnished and spatially accurate to the plan: curved sofa arrangement, central coffee table, soft area rug, warm wooden flooring, neutral walls, natural light entering through large windows. Modern, cozy, contemporary interior design with earthy tones, soft lighting, realistic materials, and lived-in details.
The right half should feel like a real photograph taken inside the house, while the left half remains a clean architectural drawing. Both halves align visually, clearly showing concept vs reality.
