Spare Room with a Focused Home Office Layout

Use the uploaded room photo as the edit target. Produce one photorealistic interior design concept from the exact same camera position, framing and perspective. Preserve the room footprint, ceiling height, structural walls, window and door locations, door swings and visible fixed services. Do not expand the room, invent openings or conceal inconvenient architecture. Infer scale conservatively from the reference; do not invent measurements. Convert the photographed spare room into a focused home office. Place a reasonably sized desk perpendicular to the visible window where the source geometry allows, with an ergonomic-looking adjustable chair and adequate space behind it. Include a low storage cabinet, a task lamp and restrained pinboard detailing. Conceal cables plausibly along furniture edges without inventing electrical outlets. Use muted blue-gray accents, pale wood and a clear work surface. Keep doors and built-in storage accessible. Match furniture perspective, contact shadows, reflections and daylight direction to the source. Keep furnishings realistically scaled and routes visibly usable. Remove only loose clutter and replaceable furnishings needed for this scheme. Return a single finished room image with no before-and-after panels, people, labels, captions, logos or watermark.
