2D Floor Plan to 3D Real Estate Render

Using the provided floor plan reference image, convert the 2D black-and-white architectural plan into a clean photorealistic 3D isometric real-estate floor plan render while preserving the original layout, room sizes, labels, and the side-by-side composition of the 1F and 2F plans. Add realistic wall thickness, light wood flooring, soft neutral wall colors, doors and windows with depth, and fully furnished interiors appropriate to each room. Keep all visible Japanese room labels in place, including 1F, 2F, 洗面所, 浴室, 収納, 階段下収納, ホール, 玄関, トイレ, L.D.K (18.0帖), 洋室 (6.0帖) for 2 rooms, ウォークインクローゼット (3.0帖), and 主寝室 (6.0帖). Stage the 1F with 1 kitchen, 1 dining table set for 4, 1 living area with sofa and coffee table, 1 toilet, 1 bathroom with tub, 1 wash area, and small plants. Stage the 2F with 3 sleeping/work rooms total: 1 bedroom with a single bed, 1 room with a desk and chair, and 1 master bedroom with a double bed, plus 2 storage spaces and 1 walk-in closet with shelving. Use a bright catalog-style presentation on a plain light background, viewed from a slightly elevated angled top-down perspective, suitable for a property sales brochure. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
