用于生成农村老房子在原结构基础上翻新改造的前后对比效果图。提示词强调保留原建筑结构、轮廓与视角，采用3:4竖版上下对比构图，上侧还原翻新前旧貌、下侧展示翻新后效果，并细化外墙、屋顶、门窗、院落等改造要点。

中文版提示词

请创建一张农村老房子在原结构基础上翻新改造的专业对比效果图。重要原则：必须保留左侧参考图的原有建筑结构、轮廓、房屋布局和构图视角；这是翻新改造而非重建，保持原有承重墙、房屋进深、开间尺寸；完全还原参考图的拍摄角度、距离和构图比例。构图布局：3:4竖版比例，上下对比构图，上侧完全复制上传的老房子参考图原貌（破旧、斑驳、杂乱），下侧在相同结构上展示翻新后效果（整洁、现代、温馨），中间以细线分隔，顶部标注“翻新前｜翻新后”，两侧视角、透视、构图完全一致，建筑轮廓线必须完全一致。翻新要点（在原结构上改造）：保持原有高度、宽度、进深不变，保留墙体位置与承重结构，维持屋顶坡度形态，保持门窗洞口位置（可扩大但不超过30%）；外墙在原墙体上做保温层加新涂料（白色/米色/浅灰），局部保留或修复青砖石材；屋顶更换为深灰或黑色瓦片，保留烟囱位置；门窗在原位置更换现代门窗系统、深色铝合金或木框架加大玻璃；院落在原有范围内重新铺装（灰色石材/仿古砖），保留院墙位置、台阶位置换现代材质，增加绿植与灯光。现代化细节不破坏结构：空调外挂隐藏于格栅后、墙面线性灯带、智能门禁、金属装饰线条、局部木格栅遮阳、窗台花箱。设计标注（下侧用细线标注）：“外墙保温+防水涂料”“原结构保留，表面翻新”“高级仿古瓦更换”“断桥铝窗+中空玻璃”“原门洞扩大，现代门框”“石材地面翻新”“智能照明系统”“保留承重墙，内部优化”。视觉要求：超高清渲染、真实建筑摄影质感、自然光照、下侧室内透出温暖灯光、新旧对比明显但和谐，材质真实（涂料质感、瓦片光泽、玻璃反射），前卫设计感与传统结构融合。设计理念：在尊重原有建筑的基础上，通过表面材料更新、细节优化、功能提升，实现从破旧到现代宜居的蜕变——这是修缮翻新，不是推倒重建。

英文版提示词

Create a professional before-and-after comparison image of a rural old house renovated on its original structure. Key principles: strictly preserve the original building structure, outline, layout, and viewing angle of the reference image; this is renovation, not rebuilding—keep the load-bearing walls, depth, and bay dimensions; fully restore the reference image's shooting angle, distance, and composition ratio. Layout: 3:4 vertical, top-bottom comparison; the top half exactly reproduces the uploaded old-house reference image (dilapidated, mottled, cluttered), the bottom half shows the renovated result on the same structure (clean, modern, warm); separate the halves with a thin line and label "Before Renovation | After Renovation" at the top; both sides must have identical perspective, composition, and building outline. Renovation points (on the original structure): keep the original height, width, and depth; preserve wall positions and load-bearing structure; maintain roof slope; keep door/window openings (may be enlarged by no more than 30%); exterior walls get insulation plus new coating (white/beige/light gray), preserving or repairing some original brick/stone; the roof is replaced with dark gray or black tiles, keeping the chimney position; doors/windows are replaced with modern systems at the original positions, dark aluminum or wood frames with large glass; the courtyard is repaved within the original area (gray stone/antique brick), keeping the courtyard wall position and replacing step positions with modern materials, adding greenery and lighting. Modern details that do not break the structure: external AC units hidden behind grilles, linear wall lighting, smart access control, metal decorative lines, partial wooden grille sunshades, and window boxes. Design annotations (thin-line labels on the bottom half): "Exterior insulation + waterproof coating," "Original structure preserved, surface renovated," "Premium antique tile replacement," "Broken-bridge aluminum windows + insulating glass," "Original door opening enlarged with modern frame," "Stone floor renovation," "Smart lighting system," "Load-bearing walls preserved, interior optimized." Visual requirements: ultra-high-definition rendering with realistic architectural photography quality, natural soft daylight, warm indoor light visible in the bottom half, obvious yet harmonious old-new contrast, realistic materials (coating texture, tile gloss, glass reflection), and a seamless fusion of avant-garde design with the traditional structure. Design concept: on the basis of respecting the original building, achieve a transformation from dilapidated to modern and livable through surface material renewal, detail optimization, and functional upgrade—this is restoration and renovation, not demolition and rebuilding.
