Redesign an interior while preserving the room

Redesign the supplied room in [DESIGN STYLE] for [ROOM PURPOSE AND USERS].

Preserve the exact architecture and camera view: wall positions, ceiling height, floor plan, doors, windows, built-in fixtures, stairs, structural columns and perspective. Keep [ITEMS THAT MUST REMAIN]. Remove or replace only [ITEMS ALLOWED TO CHANGE]. Introduce a coherent palette of [COLOURS AND MATERIALS], practical furniture at realistic scale, clear walking space and lighting suitable for [TIME OR USE].

Respect power points, plumbing, door swings, window access and circulation. Do not enlarge the room, move openings, distort lines, hide structural constraints, add impossible daylight or create furniture that cannot fit. Return a photorealistic concept visual, not a construction claim, and list any design assumption separately.
