极简建筑手绘插画

Create a minimal hand-drawn architectural artwork of [STRUCTURE] on warm ivory paper. Show the structure as a simple, elegant ink sketch with clean imperfect lines, subtle pencil shading, tiny handwritten annotations, and a few delicate architectural details. Keep the composition airy with plenty of blank space, muted earthy tones, soft paper texture, and an authentic handmade travel-journal feel. No photorealism, no heavy details, no clutter — simple, artistic, and refined.
