จากภาพร่างสู่สถาปัตยกรรม

Upload the building sketch as the sole reference for this one edit. Turn that drawing into a single photoreal exterior of the near-future building type specified in the request, and keep the sketch's massing: how many main volumes there are, their relative heights, the roofline, and the large openings. Do not add a second tower, an extra wing, or a different footprint. Use the requested materials, or glass, pale metal, and cast stone by default under clear daylight, on a quiet plaza with no people close to the camera. Stay near the sketch's viewpoint. No logos, signage, flags, or watermarks. This step only swaps the drawing for the building. A later material change is a separate generation: upload this result as the current image, leave the original sketch available for comparison, and ask for one change only. User request: Turn my uploaded courtyard sketch into a glassy civic library with the same three volumes, the tall central roof, and the wide ground-floor opening.
