Peter Zumthor, thinking, standing, hands behind back, simple white shirt, black trousers, shoes polished, bespectacled, gray hair combed back, gentle facial expression, surrounded by architectural models, blueprints, pencils, eraser, ruler, desk lamp, wooden desk, bookshelves filled with architecture books, natural light pouring through large windows, calm atmosphere, minimal decor, concrete floor, industrial style, close-up on face, soft focus on background, warm lighting, shallow depth of field.
