Create a world-class official real estate interior sales proposal board for a self-created premium property brand called "AURELIS HABITAT", designed as a flagship developer presentation sheet for an international residential project. The image must fully preserve the exact composition logic, information hierarchy, modular board structure, and premium sales-sheet rhythm of a professional bedroom proposal page: a large photoreal master bedroom hero rendering occupying the upper-left main zone, a compact technical plan drawing and a front elevation drawing stacked in the upper-right zone, and a full-width lower specification system containing material finishes, furniture and fixtures, storage detail, lighting plan, notes, color palette, key features, and official brand information. The whole board must feel more precise, more complete, more mature, and more like a true developer’s official sales proposal board, while the finished bedroom remains the absolute visual hero. Overall board composition: Use a clean horizontal presentation-board layout on a warm off-white background with highly disciplined margins, modular spacing, and elegant grid alignment. The upper-left zone must contain one large, beautifully rendered master bedroom interior in a straight-on view. The upper-right zone must contain a top-down room layout plan above and a front elevation drawing below, both precisely dimensioned and professionally labeled. The entire lower third must become a structured developer information band divided into refined modules with consistent spacing, subtle rules, and premium architectural typography. The page must feel balanced, intelligent, spacious, and internationally credible, like a real branded developer marketing presentation. Hero bedroom rendering: Design a calm, premium, globally marketable master bedroom with a centered bed composition. The bed must sit exactly on axis against a highly refined feature wall with elegant vertical paneling, concealed LED strip lighting, soft neutral upholstery, and clean symmetrical proportions. Add minimal bedside tables, one refined pendant light, one discreet bedside lamp, a built-in wardrobe or display cabinet to the left, and a large window with elegant blinds to the right. Include one restrained artwork above the bed, a soft premium rug, and only a few carefully curated styling objects. The rendered room must feel like a flagship show-unit bedroom: warm, quiet, polished, and ready for luxury property sales use. Orbit-level refinement: Push the bed wall detailing to a higher level of architectural precision. Make the panel joints, lighting reveals, wardrobe door proportions, bedside alignment, ceiling recess lines, and furniture spacing feel extremely exact and mature. The hidden lighting must be soft and expensive, the wall composition must feel fully resolved, and the bedroom must immediately communicate high-end developer quality rather than generic interior styling. Interior material language: Use a globally premium warm-minimal palette with ivory walls, soft beige and taupe textiles, pale stone or polished light flooring, warm smoked walnut or light oak cabinetry, subtle bronze or black metal accents, soft indirect lighting, and refined glass reflections. All materials must look tactile and masterfully realistic: elegant wood grain, matte wall paint, soft fabric depth, delicate joinery, clean stone veining, and controlled shadow transitions. Technical drawing zone: The upper-right technical area must feel like real professional design documentation. The top plan drawing should show the bedroom layout with bed footprint, circulation clearances, cabinet depth, window position, and precise dimension strings. The elevation drawing beneath must show the exact bed wall composition, artwork, lighting, and cabinetry alignment. Use thin black and warm-gray architectural lines, measured scale marks, dimension ticks, and clean English-only annotations. The drawings must match the rendered room precisely and feel highly standardized, elegant, and believable. Developer proposal system: Transform the lower information band into a complete official developer proposal strip. Divide it into clear modules with refined English headers such as: - MATERIAL & FINISHES - FURNITURE & FIXTURES - STORAGE DETAIL - LIGHTING PLAN - NOTES - COLOR PALETTE - KEY FEATURES The MATERIAL & FINISHES module should contain premium swatches and concise labels for wall panel, wardrobe finish, flooring, glass finish, ceiling finish, skirting, and upholstered headboard panel. The FURNITURE & FIXTURES module should show small, elegant cutout-style icons or mini product visuals for bed, bedside table, pendant, rug, stool, and cabinet. The STORAGE DETAIL module should include a tiny wardrobe elevation or drawer organization diagram. The LIGHTING PLAN module should include a miniature ceiling-lighting and LED-strip diagram. The NOTES module should contain a few short professional English specification lines. The COLOR PALETTE module should show disciplined chips in ivory, beige, taupe, walnut brown, charcoal, and soft grey. The KEY FEATURES module should include small icons with short labels such as ample storage, modern elegance, warm lighting, space efficiency, easy maintenance, and ergonomic planning. Port-level brand completion: Make the entire page feel like the front page of a global developer’s official interior product manual. Add a subtle project code, residence type label, room category name, material index references, and module naming logic. Introduce restrained presentation-board identifiers such as unit type, bedroom package name, finish package version, and drawing reference codes. These details must feel authentic, minimal, and fully integrated into the board, never noisy. Brand presentation: Integrate a minimal official brand block for AURELIS HABITAT in the bottom-right area. Add a refined English headline in the upper-left such as "CALM BY DESIGN". Add a smaller supporting line beneath it such as "Master Bedroom Proposal for Modern Urban Living". In the brand block, include a minimal logo, a descriptor such as "Interior / Architecture / Residential Development", and a discreet footer line with project-style reference information. Typography must feel international, architectural, restrained, and premium. Lighting and realism: Use extremely soft architectural lighting in the rendered bedroom: gentle daylight from the window, subtle concealed LED glow behind the headboard, refined pendant illumination, and delicate recessed ceiling lights. The rendering must feel clean, bright, and highly realistic, with soft contact shadows, faint airborne dust in the light, elegant global illumination, and a polished de-AI finish. Commercial goal: The final artwork must feel like an award-level international developer sales board: highly architectural, emotionally aspirational, technically informative, globally polished, and commercially persuasive. Preserve the exact hero-render plus technical-drawings plus lower-specification-band logic, while elevating it into a more precise, more brand-complete, and more authentic official developer proposal presentation.
