enhance this architectural floor plan top down plan view with improved materials and realistic textures while strictly keeping the image as a floor plan drawing style requirement very important this must remain a top down architectural floor plan not a perspective render do not convert the image into a 3d render or interior perspective maintain the plan view architectural presentation style only improve textures material indication shadows and graphic clarity the result should look like a high end real estate floor plan with realistic materials not a sketch layout and geometry preservation do not modify the layout walls furniture positions or proportions do not mirror rotate flip or reinterpret any element of the plan the orientation of the plan must remain exactly the same as the original image dimensions and text all dimensions numbers and annotations must remain exactly as they appear do not rotate flip recreate or redraw any numbers numbers must remain readable and in the correct orientation do not remove or reinterpret any measurement text stair orientation lock the staircase must remain exactly in the same position and orientation as the original plan do not flip mirror or rotate the stairs step direction must stay identical to the original drawing only enhance the material texture of the stairs the roof of the first floor is visible in the floorplan and should be turned into black metal sheet material lower floor reference important a faint architectural underlay of the lower floor is visible in the image this lower floor drawing is only a background reference and must not be interpreted as part of the current floor plan it must remain very light subtle and semi transparent similar to a guide layer in architectural drawings do not add materials furniture or details to this lower floor underlay the roof of the first floor visible in the plan should be rendered with a black metal sheet material the visual focus and material enhancement must be only on the top floor plan material matte light concrete same tone as the floor strict object preservation do not change the shape of furniture or architectural elements all objects must keep their original geometry and dimensions colors beige warm grey soft seating surface goal improve material realism textures and subtle shadows while preserving the exact architectural plan no layout changes no object reinterpretation no perspective rendering no geometry modifications
