create a high end photorealistic architectural visualization based exactly on the provided png reference image the goal is to convert the sketchup style reference image into a clean realistic client ready photorealistic render while preserving the architecture structure geometry proportions camera angle material logic and all visible elements 100 exactly as shown in the reference this is not a redesign this is not a furnishing proposal this is not a creative reinterpretation this is only a photorealistic version of the exact same proposed mezzanine construction 1 absolute geometry lock highest priority preserve 100 exactly original camera angle original elevated top down perspective original field of view original composition upper mezzanine gallery proportions wooden floor shape of the upper level rounded curved front corner of the wooden mezzanine floor staircase position on the right side staircase width slope height and step geometry black metal stair railing position and rhythm vertical steel column position size and proportions dark steel beam positions below the mezzanine dark steel beam dimensions and orientation left side glass floor section lower floor visible below lower door position upper door position wall positions wall heights and proportions all structural relationships exactly as shown everything must remain exactly the same as in the png reference image do not redesign anything do not reinterpret anything do not improve anything except photorealistic material rendering do not add anything do not remove anything do not move anything do not resize anything do not replace anything do not simplify the steel structure do not change the construction logic 2 critical ceiling requirement complete the ceiling as a white sloped plasterboard drywall ceiling render all ceiling planes as white painted plasterboard smooth drywall surface clean architectural finish simple and neutral following the existing sloped room geometry visually connected to the walls and upper mezzanine space without visible lamps without spotlights without led strips without skylights without ceiling decorations without exposed decorative beams without wood cladding without concrete texture important the sloped ceiling must be white plasterboard do not leave the ceiling as a blank empty void do not add ceiling fixtures do not change the room geometry 3 scene description upper level interior view of an apartment with a newly inserted steel load bearing mezzanine gallery structure the scene contains warm wooden floor on the upper mezzanine level a rounded curved wooden edge at the front corner of the upper floor black structural steel beams supporting the mezzanine one dark vertical steel column supporting the structure below a visible lower level with warm wooden floor a lower white door visible below the gallery an upper white door visible at the far wall a staircase on the right side black metal railing along the staircase a left side walkable structural glass floor section light off white plaster walls white sloped plasterboard ceilings clean empty architectural space without furniture the result must look realistic clean technically credible and suitable for client presentation 4 material lock upper wooden mezzanine floor render the upper floor as warm natural wooden planks realistic wood grain visible board joints satin finish subtle variation between boards natural medium brown tone not too orange not too yellow not glossy realistic edge thickness precise rounded curved front corner keep the plank direction and floor shape exactly as shown in the png reference the curved wooden corner must remain exactly as shown do not straighten it do not reshape it do not change it into a rectangular edge lower wooden floor render the lower floor visible below as warm natural wooden planks realistic wood grain same general tone as the upper floor satin finish realistic scale and perspective visually secondary to the upper floor do not change its position or visible extent steel structure render all steel elements as dark anthracite to black structural steel matte to satin powder coated finish realistic surface roughness subtle edge highlights physically believable thickness and weight accurate contact shadows solid load bearing appearance no chrome effect no mirror reflections no rust no decorative industrial patina the steel must look heavy structural and technically credible vertical steel column render the vertical support column as dark anthracite black steel same finish as the beams solid rectangular structural profile same exact position and dimensions as the reference realistic contact with floor and beam above no redesign no slimming no decorative treatment left side glass floor section render the left side glass floor section as walkable structural glass panels transparent or slightly translucent architectural glass realistic panel thickness clean sharp edges subtle reflections subtle light transmission believable structural support slight grey blue tint only if physically natural integrated exactly into the existing steel structure important glass is allowed only where it already exists in the floor section do not add glass anywhere else staircase render the staircase on the right side as warm natural wooden steps realistic wood grain same exact width slope and step layout as the reference natural satin finish clean architectural appearance no added riser changes no change in slope no change in width do not redesign the staircase do not add or remove steps railings render all visible railings as black painted metal only matte finish slim vertical balusters same rhythm and layout as in the reference no glass infill no glass panels no transparent railing no frameless glass no ornamental redesign important the railings must remain metal only without glass infill glass belongs only to the left side walkable floor section not to the railing walls render walls as light off white plaster subtle fine texture clean realistic surface no wallpaper no wall panels no feature wall no decorative finish no color change doors render the visible doors as white painted interior doors same exact positions and proportions as the reference simple realistic painted surface subtle panel detail small brass or warm metal handles visually secondary do not move remove enlarge or redesign the doors 5 strict no add rule critical absolutely nothing may be added to the final image do not add furniture sofa table chairs shelves cabinets lamps pendant lights spotlights led strips wall lights ceiling lights artworks decorations plants flowers carpets rugs curtains blinds people pets construction tools construction dust clutter extra beams extra columns extra doors extra windows extra glass elements glass railing infill ceiling fixtures decorative architectural elements if something is not visible in the png reference do not invent it if something is not explicitly requested do not include it the only allowed improvement is photorealistic rendering of the exact same scene 6 lighting lock use soft natural daylight only lighting must be realistic neutral to slightly warm not yellow not cold blue balanced soft and natural physically believable bright enough to read the wood steel glass walls and ceiling clearly add realistic global illumination accurate contact shadows soft shadow depth under the mezzanine natural wall bounce light subtle reflections on the glass floor section natural material response on wood steel plaster and glass avoid dramatic cinematic lighting evening mood night mood artificial lighting effects visible lamps spotlights led strips hdr look overexposed highlights overly dark shadows 7 photorealism boost upgrade the png reference into a professional architectural render using physically based materials realistic global illumination accurate contact shadows realistic steel roughness subtle steel edge highlights natural wood grain realistic wooden floor texture believable structural glass panels realistic plaster wall texture realistic white plasterboard ceiling surface correct scale perception natural exposure balanced contrast crisp but not artificial details subtle 1 2 photographic grain to avoid cgi plasticity the image must look like a clean client ready architectural visualization not a stylized concept image 8 absolute negative prompt do not add anything do not remove anything do not change anything do not change camera angle perspective composition upper floor geometry curved wooden floor edge staircase geometry steel column position steel beam positions steel beam dimensions railing layout wooden floor direction glass floor section wall positions door positions sloped ceiling geometry material assignments described above the output must remain an empty architectural scene if the model is uncertain it must keep the scene empty and faithful rather than inventing anything 9 final output final image should be ultra realistic clean technically believable empty client ready high resolution faithful to the png reference image with proper white sloped plasterboard ceiling with realistic wood black steel metal railing and glass floor section without any added objects or design changes target look 8k high end architectural render quality
