create a high end photorealistic architectural interior visualization based exactly on the provided reference image the image shows an existing apartment interior with a newly inserted dark steel mezzanine gallery structure a warm timber floor and ceiling deck an exposed steel column visible steel beams a staircase on the left side a large window with radiator on the front wall and clean off white plaster walls the goal is to transform the current sketchup style image into a realistic client presentation render while preserving the architectural geometry and technical solution exactly 1 strict preservation lock critical preserve 100 exactly original camera angle original perspective original field of view original composition room proportions floor level wall positions ceiling height impression steel mezzanine position steel beam layout steel beam dimensions steel beam orientation steel column position steel column height and thickness timber underside of the mezzanine visible floorboard direction staircase position on the left side staircase railing position window position and proportions radiator position and proportions right side wall position left side wall position front wall with window all visible structural relationships this is a technical architectural render not a redesign do not change the geometry do not move the steel column do not resize or simplify the steel beams do not change the mezzanine thickness do not change the staircase do not change the window do not change the radiator do not add furniture or decorative elements the final image must remain a photorealistic version of the same exact proposed construction 2 scene description interior view of an apartment space with a newly inserted steel load bearing mezzanine gallery construction the scene contains a dominant dark steel beam running horizontally under the mezzanine a vertical dark steel column on the left side of the window area additional dark steel beams visible under the wooden gallery deck warm timber boarding forming the underside and walking surface of the mezzanine warm wooden plank flooring on the lower level a staircase partially visible on the left side black metal railing following the staircase a large white framed window on the front wall a white radiator below the window simple light off white plaster walls clean empty interior space without furniture the result should feel realistic technically credible and suitable for client presentation before realization 3 material lock steel structure render all steel elements as dark anthracite black structural steel matte to satin powder coated finish physically realistic roughness subtle edge highlights realistic thickness and mass fine surface variation believable contact shadows no mirror reflections no chrome effect no rust no decorative industrial patina the steel must look solid heavy and load bearing important keep the steel visually strong do not make it thin elegant or decorative it is a structural element timber wood render all wooden surfaces as warm natural wood realistic visible grain satin finish subtle variation between boards natural plank direction believable joints between planks not too orange not too yellow not overly glossy wooden areas include lower floor planks underside of the mezzanine upper visible gallery deck edge staircase treads on the left side the wood should feel natural and warm but still clean and architectural walls render walls as light off white plaster subtle fine texture realistic but clean surface no decorative wallpaper no added wall panels no color change no concrete texture no brick texture the walls should stay simple and neutral so the steel structure and wood remain the main visual elements window render the front window as white painted window frame same position and size as reference realistic frame depth clean glazing soft daylight entering from this direction no curtains no blinds no external view dominance the window should remain a secondary element not the main design feature radiator render the radiator below the window as white painted metal radiator same position and proportions as reference realistic vertical ribs subtle shadows clean but not overly detailed do not remove the radiator do not replace it with a modern designer radiator railing render visible railings as black painted metal matte finish slim vertical elements crisp edges same position as reference no glass railing no ornamental railing no redesign 4 lighting use soft natural daylight entering mainly from the window area lighting must be realistic soft neutral to slightly warm not yellow not cold blue balanced physically believable bright enough to read the steel and wood details with natural shadows under the mezzanine add realistic global illumination soft contact shadows around beams and column ambient occlusion where steel meets wood and walls gentle shadow depth below the gallery natural wall brightness avoid dramatic cinematic lighting evening atmosphere artificial led lighting visible lamps spotlights overexposed window overly dark underside of the gallery hdr effect the image should look like a clean daytime architectural visualization 5 photorealism boost upgrade the reference from basic 3d model to a professional photorealistic render use physically based materials realistic global illumination accurate contact shadows realistic steel roughness subtle steel edge highlights natural wood grain visible plank texture realistic plaster texture believable window light soft shadow gradients correct scale perception natural exposure balanced contrast crisp but not artificial details subtle 1 2 photographic grain to avoid cgi plasticity the result must look like a client ready architectural visualization not a stylized concept image 6 absolute negative prompt do not add furniture sofa table chairs lamps pendant lights led strips decorations plants flowers paintings carpet curtains blinds people pets extra doors extra windows wall panels brick wall concrete feature wall luxury accessories industrial decorations visible construction workers tools construction dust do not change camera angle perspective composition steel beam position steel beam size steel column position steel column size mezzanine thickness timber deck direction staircase position railing layout window position radiator position floor direction wall geometry avoid over stylized industrial look rusty metal glossy black metal yellow lighting cold blue lighting exaggerated reflections excessive contrast unrealistic wood texture plastic cgi surfaces redesign of the space 7 final output final image should be ultra realistic clean technically believable client ready high resolution faithful to the reference image suitable for presentation of the proposed steel mezzanine structure target look 8k high end architectural render quality
