transform the existing white model of a rectangular interior space measuring 16 00 meters in length 9 00 meters in width and 4 00 meters in height into an indoor pool hall of a european grand hotel completely remove the double door on the back wall and the double door on the left wall and reconstruct those surfaces as continuous finished walls identical in thickness alignment and articulation to the adjacent walls leaving no visible trace of former openings retain the three windows on the right wall as the only openings in the space and define their frames in glossy black lacquer with a refined crisp profile insert a large indoor swimming pool positioned off centre toward the right side of the room oriented lengthwise along the full 16 00 meter dimension the pool must be generously proportioned but must leave a continuous clearly legible strip of floor along the entire left side of the room wide enough for comfortable circulation the interior of the pool basin must be fully clad in dark rich brown mosaic tiles strictly within the brown spectrum deep and earthy with no red violet purple or magenta undertones producing a warm natural brown finish the tiles should have a subtle gloss to enhance depth beneath calm pristine lightly reflective water install a polished brass pool ladder at the shallow end of the pool designed in a refined minimalist style that complements the neoclassical architecture and luxurious materials design the architecture in a refined european grand hotel neoclassical style inspired by the uploaded reference image without any gold accents on the walls the walls and ceiling must be painted in the exact same pale stone like ivory shade with no yellow or cream tint creating a perfectly unified neutral background the walls must be articulated with rectangular rigorous classical panel moldings applied in the same rhythm across all walls with the inferior half of the walls and the superior half of the walls having moldings applied separately yet maintaining consistent proportion spacing and alignment throughout subtle shadow lines should create depth without metallic ornamentation producing a restrained elegant and timeless neoclassical expression the ceiling must incorporate three transversal coffers spanning the entire 9 00 meter width of the room from wall to wall evenly distributed along the 16 00 meter length each single tiered and recessed exactly 35 00 centimeters the coffers should have crisp classical framing clean geometry and no spotlights integrated lighting or any artificial fixtures the floor surrounding the pool must consist of polished black marble with ivory marble and brass geometric inlays forming a bold high contrast symmetrical angular motif with strong graphic presence and a high gloss finish that produces refined reflections illuminate the entire space exclusively with soft diffused natural daylight entering from the three right side windows no artificial lighting fixtures of any kind no chandeliers wall sconces ceiling lights vents smoke alarms or any other additional elements
